Malaria drugs

Filed under: disease/health,military,rampage,usa — admin @ 6:59 am

Lariam (mefloquine) is one of the most widely used malaria drugs in America. Yet it has been linked to grisly crimes, like Army Staff Sgt. Robert Bales’ 2012 murder of 16 Afghan civilians, the murders of four wives of Fort Bragg soldiers in 2002 and other extreme violence.

While the FDA beefed up warnings for Lariam last summer, especially about the drug’s neurotoxic effects, and users are now given a medication guide and wallet card, Lariam and its generic versions are still the third most prescribed malaria medication. Last year there were 119,000 prescriptions between January and June. Though Lariam is banned among Air Force pilots, until 2011, Lariam was on the increase in the Navy and Marine Corps.

The negative neurotoxic side effects of Lariam can last for “weeks, months, and even years,” after someone stops using it, warns the VA. Medical and military authorities say the drug “should not be given to anyone with symptoms of a brain injury, depression or anxiety disorder,” reported Army Times–which is, of course, the demographic that encompasses “many troops who have deployed to Iraq or Afghanistan.” In addition to Lariam’s wide us in the military, the civilian population taking malaria drugs includes Peace Corps and aid workers, business travelers, news media, students, NGO workers, industrial contractors, missionaries and families visiting relatives, often bringing children.

What makes Lariam so deadly? It has the same features that made the street drug PCP/angel dust such an urban legend in the 1970s and 1980s. It can produce extreme panic, paranoia and rage in the user along with out-of-body “disassociative” and dream-like sensations so that a person performing a criminal act often believes someone else is doing it. An example of such disassociative effects was seen in Staff Sgt. Robert Bales’ rampage; according to prosecutors at his trial, Bales slipped away from his remote Afghanistan post, Camp Belambay, in a T-shirt, cape and night-vision goggles and no body armor to attack his first victims. He then returned to the base and “woke a fellow soldier, reported what he’d done, and said he was headed out to kill more.”

In addition to Bales’ 2012 attacks and the 2002 Fort Bragg attacks, Lariam was linked in news reports to extreme side effects in an army staff sergeant in Iraq in 2005 and to the suicide of an Army Reservist in 2008.

Former Army psychiatrist Elspeth Cameron Ritchie, former U.S. Army Major and Preventive Medicine Officer Remington Nevin and Jerald Block with the Portland Veterans Affairs Medical Center agree in a recent paper that Lariam may be behind “seemingly spectacular and impulsive suicides.” It can produce “derealization and depersonalization, compulsions toward dangerous objects, and morbid curiosity about death,” they write, describing frequent hallucinations “involving religious or morbid themes” and “a sense of the presence of a nearby nondescript figure.” The researchers refer to two reports of people jumping out of windows on Lariam under the false belief that their rooms were on fire.

Lariam is one of five malaria drugs listed by the CDC for people who will be exposed to malaria. Other drugs include Malarone, a combination of the drugs atovaquone and Proguanil, Aralen (chloroquine,) primaquine and the antibiotic doxycycline marketed as Vibramycin. None of the drugs are ideal–Malarone can have renal effects and Aralen can have liver, blood and skin effects. Some do not work right away or are ineffective against resistant malaria strains. But the main reason for Lariam’s historic popularity is that it is taken weekly, unlike all the other drugs (except chloroquine) which are taken daily. Some travelers also report that Lariam is cheaper than other malaria drugs and say they only experience symptoms like memory loss and vivid nightmares. Still, since awareness of Lariam’s dangers, many users are now required to read and sign an informed consent form.

Early Example of Public Funding of Pharma Profits

Lariam was an early example of “technology-transfer” between publicly funded and academic research and Big Pharma, driven by the Bayh-Dole Act of 1980. The Bayh-Dole Act dangled the riches of “industry” before medical institutions just as the former were floundering and the latter was booming, observes Marcia Angell, former editor-in-chief of the New England Journal of Medicine. Turning universities into think tanks for Big Pharma has been so profitable, Northwestern University made $700 million when it sold Lyrica, discovered by one of its chemists, to Pfizer enabling it to build a new research building.

Lariam was developed by the Walter Reed Army Institute of Research (WRAIR) in the 1960s and ’70s after a drug-resistant strain of malaria did not respond to medications and sickened troops during the Vietnam War. Though Lariam was developed with our tax dollars, all phase I and phase II clinical trial data were given to Hoffman LaRoche and Smith Kline free of charge in what was the first private public partnership between the U.S. Department of Defense and Big Pharma . You’re welcome! It was approved by the FDA in 1989.

Roche, which retained the patent, did well with the government largesse. In 2009, it spent $46.8 billion to buy Genentech (for comparison the entire yearly budget of the National Institutes of Health is $60 billion a year) and its cancer drug, Avastin, makes up to $100,000 per patient per year, despite reports of its limited effectiveness for some cancers for which it is used. Nor was the testing of Lariam kosher. It was first tested on prisoners and soldiers who are not necessarily able or willing to refuse participation in clinical trials and it was also widely given to Guantanamo detainees. Phase III trials, supposed to be conducted on larger patient groups of up to 3,000 people, were not conducted at all, wrote the Journal of the Royal Society of Medicine in 2007 and “there was no serious attempt prior to licensing to explore the potential drug-drug interactions.” In fact, all users “have been involved in a natural experiment to determine the true safety margin,” says the journal, because “Consumers have been unwitting recruits to this longitudinal study, rather than informed partners.” No wonder Lariam causes adverse effects in as many as 67 percent of users.

As seen with other drugs that have neuropsychiatric effects, like the antidepressant Cymbalta and seizure drug Neurontin, the military, government and Big Pharma blamed the effects on the patients not the drugs. When the wives of four Fort Bragg soldiers were murdered during the summer of 2002–one was stabbed 50 times and set on fire–military investigators blamed “existing marital problems and the stress of separation while soldiers are away on duty,” instead of Lariam. Right. Three of the four soldiers also took their own lives.

The military, government and Big Pharma similarly blame the current suicide epidemic among military personnel on factors others than the ubiquitous psychiatric drugs in use–even though 30 percent of the victims never deployed and 60 percent never saw combat. A recent five-year study by Pharma-funded academic, government and military researchers about military suicides does not even consider the drugs given to an estimated fourth of soldiers–almost all of which carry warnings about suicide.

It is also worth noting that the alarming side-effects linked to Lariam which patients, doctors and public health officials reported for at least a decade, were not acknowledged until profits ran out and Lariam became a generic, as has happened with other risky drugs. When sentiment turned against Lariam in 2008, its manufacturer, Hoffmann-La Roche ceased marketing it in the US and now the words “Lariam” and “malaria” draw no search results on its US website. Who, us?

One group that has tried to raise awareness of the dangers of Lariam is Mefloquine (Lariam) Action, created in 1996 when founder, Susan Rose, noticed Peace Corps workers given Lariam were falling ill. Rose soon enlarged the scope of Mefloquine (Lariam) Action to include travelers and military personnel.

“This black box [the strongest FDA warning on drug packaging] officially establishes that mefloquine can cause permanent, brain damage and more. It validates what we have been saying since the beginning,” Jeanne Lese, director of Mefloquine (Lariam) Action told me. The problem is far from solved by the black box, says Lese. “The drug continues to be given out at travel clinics all over the U.S. and elsewhere every single day. What’s more, it is often prescribed with no hint to the patient about the black box, and no screening for contraindications such as history of previous depression or other neuropsych problems.” Lariam’s Checkered Past

The case of the four Fort Bragg soldiers charged with killing their wives during the summer of 2002 is not the only time Lariam has been in the news. There was also the case of Staff Sergeant Andrew Pogany who volunteered to serve in Iraq in 2003 and experienced such panic and PTSD symptoms in the war theater, he was sent back to Fort Carson and charged with “cowardly conduct as a result of fear.” Pogany and his attorney were able to prove that his reaction probably stemmed from Lariam and he received an honorable discharge. But Pogany, understandably, became a vehement advocate for the rights of soldiers with PTSD, especially those who have been given psychoactive drugs that make them worse.

The wife of a 17-year marine veteran I interviewed in 2011 reported a similar story. After being deployed twice to Iraq and once to Afghanistan, her husband developed extreme PTSD. “He went from being loving on the phone, to saying he never wanted to see me and our daughter again,” the wife said. “He said not to even bother coming to the airport to meet him, because he would walk right past us.” When the couple did reunite, the husband was frail and thin, and “the whites of his eyes were brown,” says the wife. The formerly competent drill instructor became increasingly and inexplicably unpredictable, suicidal and violent and was incarcerated in the brig at Camp Lejeune for assault in 2011. I asked the wife to ask him during her visits if he had been given Lariam and she said he said yes.

In the nonfiction book, Murder in Baker Company: How Four American Soldiers Killed One of Their Own, Lariam is also raised as a possible factor in the brutal death of Army Specialist Richard Davis. When asked about Lariam in the crime in an interview, the author Cilla McCain said, “Although it was never mentioned in court, I think if this same case were to happen today, it would definitely be considered as a defense. These soldiers were overdosing on Lariam in massive amounts because there wasn’t proper oversight. In reality, proper oversight is impossible in a war zone but steps could have been taken to make sure that overdosing didn’t occur. Even without over-dosage the Lariam issue is a volatile one at best and I’m positive we will be hearing more about the damage it has caused for years to come. Some scientists are linking Lariam directly to the historical rise of suicides in the United States.”

As a dark cloud grows over Lariam, there is both good and bad news. The good news is in 2013, the Surgeon General’s Office of the Army Special Operations Command told commanders and medical workers that soldiers thought to be suffering from PTSD or other psychological problems or even faking mental impairment may actually be Lariam victims. The bad news is a new malaria drug developed at Reed during the same time period as Lariam called tafenoquine is now fast-tracking toward FDA approval. Jeanne Lese and Remington Nevin worry that the new drug has not been adequately tested for the same types of neurotoxic effects seen with Lariam and that it will become Lariam 2.0.

Flash Floods Worst Ever

Head of the National Disaster Management Council says today’s heavy rains and flash floods are the worst he’s ever witnessed for Honiara.

Loti Yates made the statement on national radio today when announcing the NDMO’s evacuation program for people worst hit by today’s heavy torrential rains and its consequential flash floods.

Reports reaching SIBC state communities in White River, Rove, Mataniko, Koa Hill and other areas located near rivers and streams are among the worst hit areas.

Other unconfirmed reports state that the flooding Mataniko River swept away homes, livestock and a number of people – with some of the people being found in seas outside of Point Cruz.

Heavy flooding also swept away the old Mataniko Bridge in Chinatown, and most businesses and offices were forced to close early today.

One shop owner in Chinatown reportedly opened his shop and invited people to take goods for free after the behind of the building was swept away by the flooding Mataniko River.

Director of National Disaster Management Office, Loti Yates told SIBC News this current bad weather is the worst he’s seen since he took up his job as head of the NDMO.

“This event is the worst I’ve ever seen since taking up the job, that there are so much heavy rain around this area that creates this massive flash foods. Not only that, it won’t help when our drainage systems in the city are not working properly, contributing to the floods. Driving around to assess the situation myself today I was sad to notice the fact that there were children and women carrying little kids in the rain trying to evacuate themselves from the flooded areas and in some places it seems people’s belongings have been washed away by the Mataniko floods.”

Meanwhile, the National Disaster Management Office has urged road users to drive back to their homes and garage their vehicles.

NDMO Head Loti Yates told national radio today the road needs to be cleared for police and emergency response workers.

“It would be good if people just head straight to their homes rather than creating extra hurdles for emergency response workers. The police will need space to run their vehicles if we are to engage them to evacuate people from the high risk areas, we will all need space and it won’t help when everyone else wants to witness the events, creating extra traffic on our roads. I think for safety purposes please drive back to your homes, pack your vehicles and remain in the safety of your homes. That will be the biggest message I want to tell people because now the emergency response workers, like police and others working to help those affected will need space on the roads to carry out their duty.”

H7N9

Filed under: china,disease/health — admin @ 1:13 pm

Avian Influenza A (H7N9) Virus

Human infections with a new avian influenza A (H7N9) virus were first reported in China in March 2013. Most of these infections are believed to result from exposure to infected poultry or contaminated environments, as H7N9 viruses have also been found in poultry in China. While some mild illnesses in human H7N9 cases have been seen, most patients have had severe respiratory illness, with about one-third resulting in death. No evidence of sustained person-to-person spread of H7N9 has been found, though some evidence points to limited person-to-person spread in rare circumstances. No cases of H7N9 outside of China have been reported. The new H7N9 virus has not been detected in people or birds in the United States.

It’s likely that sporadic cases of H7N9 associated with poultry exposure will continue to occur in China. Cases associated with poultry exposure also may be detected in neighboring countries. It’s also possible that H7N9 may be detected in the United States at some point, possibly in a traveler returning from an affected area. Most concerning about this situation is the pandemic potential of this virus. Influenza viruses constantly change and it’s possible that this virus could gain the ability to spread easily and sustainably among people, triggering a global outbreak of disease (pandemic).

On Feb. 3, 2014, the National Health and Family Planning Commission (NHFPC) of China notified the World Health Organization (WHO) of four additional laboratory-confirmed cases of human infection with avian influenza A(H7N9) virus, including one death.

Details of the cases are as follows:

A 27-year-old man from Zhangzhou City, Fujian Province, who became ill on January 21 and admitted to the hospital on January 31. He is currently in critical condition. The patient has a history of exposure to a live poultry market.

A 59-year-old man from Loudi City, Hunan Province, who became ill on January 23 and was admitted to the hospital on January 31. He died on February 3. The patient had a history of exposure to live poultry market.

A 2-year-old female from Zhongshan City, Guangdong Province, who became ill on January 31 and was admitted to the hospital on the same day. She has a mild illness. The patient has a history of exposure to live poultry and a live poultry market.

A 76-year-old woman from Huizhou City, Guangdong Province, who became ill on January 27 and was admitted to the hospital on February 1. She is currently in serious condition. The patient has a history of exposure to live poultry.

So far, there is no evidence of sustained human-to-human transmission.

The Chinese government continues to take the following surveillance and control measures: strengthen surveillance and situation analysis; reinforce case management and treatment; conduct risk communication with the public and release information; strengthen international collaboration and communication; and conduct scientific studies.

While the recent report of avian influenza A(H7N9) virus being detected in live poultry imported from the mainland to Hong Kong SAR, shows the potential for the virus to spread through live poultry, at this time there is no indication that international spread of avian influenza A(H7N9) has occurred through humans or animals.

Further sporadic human cases of A(H7N9) infection are expected in affected and possibly neighbouring areas, especially given expected increases in the trade and transport of poultry associated with the Lunar New Year.

WHO advises that travelers to countries with known outbreaks of avian influenza should avoid poultry farms, or contact with animals in live bird markets, or entering areas where poultry may be slaughtered, or contact with any surfaces that appear to be contaminated with faeces from poultry or other animals. Travellers should also wash their hands often with soap and water. Travellers should follow good food safety and good food hygiene practices.

WHO does not advise special screening at points of entry with regard to this event, nor does it currently recommend any travel or trade restrictions.

As always, a diagnosis of infection with an avian influenza virus should be considered in individuals who develop severe acute respiratory symptoms while travelling or soon after returning from an area where avian influenza is a concern.

WHO encourages countries to continue strengthening influenza surveillance, including surveillance for severe acute respiratory infections (SARI) and to carefully review any unusual patterns, in order to ensure reporting of human infections under the IHR (2005), and continue national health preparedness actions.

Climate Change & Disease

Caribbean countries, struggling to emerge from a slump in exports and falling tourist arrivals brought on by the worldwide economic crisis that began five years ago, have one more thing to worry about in 2014.

Dominica’s chief medical officer, Dr. David John, said climate change and its effects are taking a toll on the health of people in his homeland and elsewhere in the region. “A lot of diseases will essentially create havoc among people who are already poor.”

“You have seen what is happening [with] the effects of climate change in terms of our infrastructure, but there are also significant effects with regards to climate change on health,” John said, adding that “these effects relate to the spread of disease including dengue fever and certain respiratory illnesses.” John said the Dominica government would be seeking assistance from international agencies, including the World Meteorological Organisation (WMO), to mitigate “the effects of climate change on health as it relates to dengue, leptospirosis and viral disease.”

In late 2012, the Ministry of Health in Barbados alerted members of the public about a spike in leptospirosis cases. Senior Medical Officer of Health-North Dr. Karen Springer said then that five people had contracted the severe bacterial infection, bringing the number of cases for the year to 18.

Springer explained that the disease, which includes flu-like symptoms such as fever, headache, chills, nausea and vomiting, eye inflammation and muscle aches, could be contracted through contact with water, damp soil or vegetation contaminated with the urine of infected animals. Bacteria can also enter the body through broken skin and if the person swallows contaminated food or water.

In recent years, dengue has also been on the rise throughout the Caribbean with outbreaks in Dominica, Barbados, Trinidad and Tobago, Puerto Rico and the French islands of Martinique and Guadeloupe, among other places.

Professor of environmental health at the Trinidad campus of the University of the West Indies Dr. Dave Chadee said there is ample “evidence that climate-sensitive diseases are being tweaked and are having a more significant impact on the region”.

He said he co-authored a book with Anthony Chen and Sam Rawlins in 2006 which showed “very clearly” the association between the changes in the seasonal patterns of the weather and the onset and distribution of dengue fever.

“There is enough evidence, not only from the Caribbean region but worldwide, that these extreme events are going to have and going to play a significant role in the introduction and distribution of these sorts of diseases in the region,” Chadee, who previously served as an entomologist at the Insect Vector Control Division of the Ministry of Health in Trinidad and Tobago, said.

“If you look at the various factors that are associated with climate change, the first is heat waves. There has also been a reduction in air quality. You also see an increase in fires and the effects on people’s ability to breathe as well as the association between the Sahara dust and asthma which was demonstrated in Barbados and Trinidad recently.

“The Sahara dust which comes in from Africa brings in not only the sand but also other pathogenic agents within the sand, together with some insecticides which have been identified by people working at the University of the West Indies,” Chadee said.

Dr. Lystra Fletcher-Paul, the Food and Agriculture Organisation (FAO) representative for Guyana, said she has no doubt that climate change has contributed significantly to some of the issues related to diseases in the region.

“If you look at some of the impacts of climate change, for example drought, with drought you are going to increase the amount of irrigation that you are going to be applying to the crops. And irrigation water is a source of pesticides or even chemicals, depending on where that source of water is and that could lead to problems in health,” she said.

“Similarly with the extreme events, if you are talking about floods, there can be contamination of the fresh-water supply.”

The FAO representative is adamant that there is too much “talk” in the Caribbean and too little “implementation”.

“We have had the conversation, so what we need to do now is put the systems in place to mitigate and adapt to climate change,” she said. Using land-use planning as an example, Fletcher-Paul said, “A lot of what we see happening in St. Vincent and St. Lucia may not necessarily have taken place if we had proper land-use planning.”

A slow-moving, low-level trough on Dec. 24 dumped hundreds of millimetres of rain on St. Vincent and the Grenadines, St. Lucia and Dominica, killing at least 13 people. The islands are still trying to recover.

“So we need to take some hard decisions in terms of where we would allow development to take place or not,” Fletcher-Paul said.

Chadee said the poor would always be at a disadvantage in climate change scenarios and they will suffer the most from sea level rise when you have salt water intrusion into fertile agricultural land, rendering them unsuitable for food production. “A lot of diseases will essentially create havoc to people who are already poor. The adaptability of the poor versus the rich within the Caribbean region will be tested because if the poor are no longer able to produce some of their food, this would then lead to health problems.”

He explained that if the poor are no longer able to have a particular diet this would make them susceptible to a number of diseases.

“With the Caribbean region having developing states, and especially Small Island Developing States, we do have a unique situation where the resources have to be put in place, especially for adaptation,” Chadee said.

“It’s almost like the wall of the reservoir has been breached and you know that the water is coming. You don’t know how high the water level is going to be but you know it’s coming, so what do you do? And that essentially is the scenario in which we have found ourselves in the Caribbean,” Chadee added.

Bubonic Plague

Filed under: congo,disease/health,global islands,india,indonesia,madagascar — admin @ 6:27 am

It may be 2013, but the African island of Madagascar is facing a public health threat straight out of the Middle Ages: At least 20 people in the country’s northwest died last week from the bubonic plague, and 2012 saw some 256 plague cases and 60 deaths–more than in any other country in the world.

One major problem seems to be the rat-infested prisons like the notorious facility in Antanimora, which holds 3,000 inmates. The International Committee of the Red Cross in October warned that the facility’s overcrowding and poor sanitary conditions present a serious plague threat–not just to prisoners, but to those outside its walls, too, since inmates’ relatives can catch the disease when they visit the facility, and detainees are often released without having been treated.

To stem infections, authorities have been disinfecting the prison and trying to trap rats. Officials face an uphill struggle. Prisoners are jammed together in cramped quarters teeming with insects and rodents.

The dreaded bacterial infection, which is carried by the fleas that live on rodents, was responsible for an astounding 25 million deaths in Europe during the 14th century, with periodic outbreaks through the beginning of the 20th century, and continued scattered incidents in countries including the Democratic Republic of Congo, Kyrgyzstan, India, Indonesia and Algeria. It produces painful swelling of the lymph nodes and kills up to two thirds of those afflicted–though with antibiotics the mortality rate drops below 15%.

In addition to plentiful rats and too many inmates in an unhygienic prison, Madagascar’s public health system is a shambles. “The aim is to make sure there is no let-up in the fight against the plague in prisons,” said Christoph Vogt, head of the ICRC delegation in Madagascar. He’s got his work cut out for him.

MERS-CoV

Filed under: disease/health,india,malaysia,saudia arabia,tunisia — admin @ 4:05 am

A 66-year-old Tunisian man has died from the new coronavirus following a visit to Saudi Arabia and two of his adult children were infected with it.

His sons were treated and have since recovered but the rest of the family remains under medical observation. The cases are the first for Tunisia and indicate that the virus is slowly trickling out of Saudi Arabia, where more than 30 coronavirus cases have been reported. There have been at least 20 deaths worldwide out of 40 cases.

The Tunisian fatality, a diabetic, had been complaining of breathing problems since his return from the trip and died in a hospital in the coastal Tunisian city of Monastir. Many previous coronavirus patients have had underlying medical problems, which WHO said might have made them more susceptible to getting infected. There is no specific treatment for the disease, but the agency has issued guidelines for how doctors might treat patients, like providing oxygen therapy and avoiding strong steroids.

The new virus has been compared to SARS, an unusual pneumonia that surfaced in China then erupted into a deadly international outbreak in early 2003. Ultimately, more than 8,000 SARS cases were reported in about 30 countries and over 770 people died from it.

The new coronavirus is most closely related to a bat virus and is part of a family of viruses that cause the common cold and SARS. Experts suspect it may be jumping directly from animals like camels or goats into people, but there isn’t enough proof to narrow down a species yet. The virus can cause acute respiratory disease, kidney failure and heart problems.

The Saudi Arabian cities of Mecca and Medina will receive millions of pilgrims from around the world during the Muslim holy month of Ramadan, which falls in July and August this year.

The Middle East Respiratory Syndrome Corona virus (MERS-CoV), which was first reported in Saudi Arabia and is now slowly spreading to other countries like the U.K., Jordan, France, and Tunisia.

Strange enough, despite the fact that Kerala has a lot of women working in the health sector in the Middle East and that there is good traffic between the Middle East and Kerala, active surveillance for the illness has not yet been launched.

The infection is still being reported in small clusters, even outside Middle East countries and hence no screening at airports has been advised by WHO. Yet, given Kerala’s widespread links to the Middle East and the fact that so many Malayalis live in very crowded environs in these countries, it is very much possible that the virus could come into Kerala.

Human-to-human transmission of the virus has been confirmed with many cases being reported among family members and through hospital-acquired (nosocomial) infections. The virus has so far resulted in 40 confirmed cases of severe respiratory disease, including 20 deaths.

The MERS-CoV belongs to the same family as the SARS virus, which had erupted as a major global outbreak in 2003. The novel CoV, however, though more lethal than SARS virus, does not spread from humans as easily as SARS.

Till now, all the confirmed cases of MERS-CoV has had some link to the Middle East – persons who travelled to the destination, their close family members, or health workers who came into contact with confirmed cases in hospitals.

Man dies of flu-like illness

Filed under: cnmi,disease/health — admin @ 11:44 am

THE Commonwealth Health Center saved the lives of two pregnant women and their babies from adult respiratory distress syndrome, or ARDS, but a man died of the flu-like illness.

Commonwealth Health Care Corp. chief executive officer Esther Muna, in a press conference yesterday, said they wanted to make it clear that there was no influenza outbreak in the CNMI.

ARDS, according to CHC federal consultant Dr. Poki Namkung, is a devastating condition that is related to many causes including severe pneumonia.

In the three cases admitted at CHC, Namkung said they didn’t make a definitive finding although many tests were conducted. The influenza tests are negative so far but the hospital is doing further tests, she added.

Namkung admitted that they have not found a bacterial source yet but added that ARDS can be caused by chemical, bacterial or viral causes. She said ARDS destroys the ability of the lungs to function and the mortality rate in such cases is very high.

She said it was a blessing that the women are now improving despite that fact that both of them were pregnant when they were admitted.

Muna said one of the women was admitted on May 13, while the other was admitted on May 16.

The third case, a middle-aged man, was admitted on May 14 and died on May 17.

Muna said “the cause of death is unknown at this time” but the patient had a flu-like illness and was admitted at CHC for severe respiratory illnesses.

Muna said there was no link between the three cases.

“We would like the public to know that we are very, very concerned about the situation and we are working extremely hard and have done an exceptional job in attending to the patients,” she said.

Muna said there is no evidence of H7N9 infection in the three cases, but the U.S. Centers for Disease Control is asking for further testing. CHC, she added, is in constant communication with the federal agency.

Nurse supervisor Wilma Gamundoy said when the two pregnant were admitted they had to “evacuate” the babies in the wombs so they could treat the mothers. The babies were delivered through Caesarian-section. The infants had to be put on ventilators at first but were finally taken off yesterday. The mothers, too, are now improving, Gamundoy said.

Muna is urging the public to take extra precautions.

The symptoms of ARDS include fever, coughing and difficulty in breathing.

Chikungunya – Malaria

Filed under: disease/health,png — admin @ 11:30 am

Avoiding mosquito bites is the key to avoid Chikungunya fever because the virus is carried by infected Aedes mosquitoes.
This is according to a fact sheet distributed by the Papua New Guinea Institute of Medical Research (PNGIMR). The factsheet says that if a person is infected and bitten by a mosquito, that mosquito may later spread the virus biting another person. These mosquitoes can be identified by the white stripes on their black bodies and legs and aggressive during the day.
Symptoms of appear on average 3 to 7 days after being bitten by an infected mosquito and most patients feel better after a few days or weeks. Some people may develop longer term joint pain. Some of the symptoms include; sudden onset of fever, severe joint pain in arms and legs, headache, muscle pain, nausea and rash. To avoid been infected, people should avoid mosquito bites. According to the factsheet, a person with chikungunya fever should limit their exposure to mosquito bittes to avoid infecting other people.
The mosquitoes carrying the virus live in a wide range of habitats. One main area is standing or stagnant water, where mosquito eggs develop into adults.
There is no specific medication or vaccine available for chikungunya but it should be treated with panadol and not aspirin.

ALMOST 90 per cent of the country’s population is at risk of malaria.
Each and every district in our country continues to record malaria cases. In fact, PNG has the highest malaria burden in the Western Pacific Region. Approximately 1.7 million clinical cases of the disease are recorded in the health facilities each year, and up to 600 deaths.
Reported incidences of clinical malaria was 1.6 million in 2008.
Last year reported infections were 1,1 million. During the same period, the reported number of deaths was also reduced by one third from over 600 to 431 in 2012.
While celebrating Malaria Day last week in Port Moresby, Health and HIV/AIDS Minister Michael Malabag said PNG has made some significant progress in reducing the malaria burden and ultimately achieving elimination.
“All our health indicators do not look very good compared to the rest of the pacific, and I believe that we can improve many of our health indicators simply by concentrating our efforts on very high health impact diseases of which malaria happens to top the list,” Mr Malabag said. Rotary Against Malaria, Oil Search, and Population Services International (PSI) were acknowledged as major partners in the fight against malaria.
He noted the health department has pooled substantial resources from external sources to fund our efforts to control malaria.
From 2005-2009 the Global Fund had provided over $US20 million under the round three grant. In the current round eight grant, the global fund has again made available anther $US 120 million. AusAID has provided $A3 million for the past three years and WHO has continued to provide technical support.
Furthermore, the minister said he is encouraged by the partnerships between the private sector and the department in malaria control efforts. The minister left a challenge with other members of parliament and provincial governments to recognise the impact of malaria on the lives of people and take action.

Neoliberal plague: AIDS and global capitalism

Dengue fever – a global growing threat

Filed under: disease/health — admin @ 4:12 pm

Dengue and severe dengue

* Dengue is a mosquito-borne viral infection.
* The infection causes flu-like illness, and occasionally develops into a potentially lethal complication called severe dengue.
* The global incidence of dengue has grown dramatically in recent decades.
* About half of the world’s population is now at risk.
* Dengue is found in tropical and sub-tropical climates worldwide, mostly in urban and semi-urban areas.
* Severe dengue is a leading cause of serious illness and death among children in some Asian and Latin American countries.
* There is no specific treatment for dengue/ severe dengue, but early detection and access to proper medical care lowers fatality rates below 1%.
* Dengue prevention and control solely depends on effective vector control measures.

Dengue is a mosquito-borne infection found in tropical and sub-tropical regions around the world. In recent years, transmission has increased predominantly in urban and semi-urban areas and has become a major international public health concern.

Severe dengue (previously known as Dengue Haemorrhagic Fever) was first recognized in the 1950s during dengue epidemics in the Philippines and Thailand. Today, severe dengue affects most Asian and Latin American countries and has become a leading cause of hospitalization and death among children in these regions.

There are four distinct, but closely related, serotypes of the virus that cause dengue (DEN-1, DEN-2, DEN-3 and DEN-4). Recovery from infection by one provides lifelong immunity against that particular serotype. However, cross-immunity to the other serotypes after recovery is only partial and temporary. Subsequent infections by other serotypes increase the risk of developing severe dengue.

Global burden of dengue

The incidence of dengue has grown dramatically around the world in recent decades. Over 2.5 billion people – over 40% of the world’s population – are now at risk from dengue. WHO currently estimates there may be 50–100 million dengue infections worldwide every year.

Before 1970, only nine countries had experienced severe dengue epidemics. The disease is now endemic in more than 100 countries in Africa, the Americas, the Eastern Mediterranean, South-east Asia and the Western Pacific. The American, South-east Asia and the Western Pacific regions are the most seriously affected.

Cases across the Americas, South-east Asia and Western Pacific have exceeded 1.2 million cases in 2008 and over 2.3 million in 2010 (based on official data submitted by Member States). Recently the number of reported cases has continued to increase. In 2010, 1.6 million cases of dengue were reported in the Americas alone, of which 49 000 cases were severe dengue.

Not only is the number of cases increasing as the disease spreads to new areas, but explosive outbreaks are occurring. The threat of a possible outbreak of dengue fever now exists in Europe and local transmission of dengue was reported for the first time in France and Croatia in 2010 and imported cases were detected in three other European countries. A recent (2012) outbreak of dengue on Madeira islands of Portugal has resulted in over 1800 cases and imported cases were detected in five other countries in Europe apart from mainland Portugal.

An estimated 500 000 people with severe dengue require hospitalization each year, a large proportion of whom are children. About 2.5% of those affected die.

Transmission
Aedes aegypti; adult female mosquito taking a blood meal on human skin.
WHO/TDR/Stammers

The Aedes aegypti mosquito is the primary vector of dengue. The virus is transmitted to humans through the bites of infected female mosquitoes. After virus incubation for 4–10 days, an infected mosquito is capable of transmitting the virus for the rest of its life.

Infected humans are the main carriers and multipliers of the virus, serving as a source of the virus for uninfected mosquitoes. Patients who are already infected with the dengue virus can transmit the infection (for 4–5 days; maximum 12) via Aedes mosquitoes after their first symptoms appear.

The Aedes aegypti mosquito lives in urban habitats and breeds mostly in man-made containers. Unlike other mosquitoes Ae. aegypti is a daytime feeder; its peak biting periods are early in the morning and in the evening before dusk. Female Ae. aegypti bites multiple people during each feeding period.

Aedes albopictus, a secondary dengue vector in Asia, has spread to North America and Europe largely due to the international trade in used tyres (a breeding habitat) and other goods (e.g. lucky bamboo). Ae. albopictus is highly adaptive and therefore can survive in cooler temperate regions of Europe. Its spread is due to its tolerance to temperatures below freezing, hibernation, and ability to shelter in microhabitats.
Characteristics

Dengue fever is a severe, flu-like illness that affects infants, young children and adults, but seldom causes death.

Dengue should be suspected when a high fever (40°C/ 104°F) is accompanied by two of the following symptoms: severe headache, pain behind the eyes, muscle and joint pains, nausea, vomiting, swollen glands or rash. Symptoms usually last for 2–7 days, after an incubation period of 4–10 days after the bite from an infected mosquito.

Severe dengue is a potentially deadly complication due to plasma leaking, fluid accumulation, respiratory distress, severe bleeding, or organ impairment. Warning signs occur 3–7 days after the first symptoms in conjunction with a decrease in temperature (below 38°C/ 100°F) and include: severe abdominal pain, persistent vomiting, rapid breathing, bleeding gums, fatigue, restlessness, blood in vomit. The next 24–48 hours of the critical stage can be lethal; proper medical care is needed to avoid complications and risk of death.

Treatment

There is no specific treatment for dengue fever.

For severe dengue, medical care by physicians and nurses experienced with the effects and progression of the disease can save lives – decreasing mortality rates from more than 20% to less than 1%. Maintenance of the patient’s body fluid volume is critical to severe dengue care.

Immunization

There is no vaccine to protect against dengue.

Dengue fever is the world’s fastest growing mosquito-borne disease. Over 50 million people suffer from dengue fever each year, and 40% of the world’s population may be at risk. It is quickly becoming even more widespread, and is growing in severity.

Dengue symptoms range from mild and flu-like to high fever, rash, severe headache, pain behind the eyes, muscle and joint pain. The joint pain can be so severe that dengue has been given the name ‘breakbone fever’. Nausea, vomiting, and loss of appetite are also common. In the more severe form, sometimes called dengue haemorrhagic fever (DHF), blood vessels start to leak and cause bleeding from the nose, mouth, and gums. Without prompt treatment, the blood vessels can collapse, causing shock (dengue shock syndrome) and ultimately fatality.

Around 25,000 people die from Dengue Fever each year. Severe cases require hospitalization and constant monitoring. Dengue is also an extremely expensive disease, estimated to cost the global economy over US$5 billion per year.

Dengue fever occurs in most tropical areas of the world. It is common in Asia, the Pacific, Australia, Latin America and the Caribbean and is continuing to spread having now reached North America. A recent Natural Defence Resource Council report shows that 28 US states are now at risk.
Current control methods aren’t working

There is neither specific medication nor vaccine for dengue. The only way currently to control the disease is to control the mosquito which spreads it: the dengue mosquito, Aedes aegypti.

Existing methods of controlling the dengue mosquito, which include spraying or fogging using chemical pesticides, have failed to stop the spread of the disease. That’s partly because the mosquitoes have developed resistance, but also because the Aedes aegypti mosquito lives in and around human habitation – even breeding happily in vases, water jars and other vessels in people’s houses – so it can be very difficult to reach.

The Oxitec approach

Using advanced genetics and molecular biology Oxitec has developed a new and innovative solution to controlling the dengue mosquito, Aedes aegypti.

The Oxitec solution harnesses the natural instincts of male mosquitoes to find females in the wild. Oxitec has used genetic modification to create ‘sterile’ male insects which seek out and mate with females. After an Oxitec mosquito has successfully mated with a wild female, any offspring that result will not survive to adulthood, so the mosquito population declines.

The Oxitec Control Programme is the system through which Oxitec mosquitoes are released and monitored in a dengue-hit area over a predetermined and sustained period of time. By applying the Oxitec Control Programme to an area, the mosquito population in that area can be dramatically reduced or eliminated.

The Oxitec approach is targeted at a single species, unlike conventional insecticides or pesticides which kill insects indiscriminately. This means that, as well as being more effective, it is much better for the environment than conventional tools.

The benefits

The personal cost of dengue fever for the individual is high. But dengue also places a strangle-hold on entire communities. The economic cost of dengue is phenomenal and is estimated to cost the global economy US$5 billion annually. In addition to the high cost of current control methods, and the even higher cost of caring for dengue patients, dengue outbreaks can devastate tourism in countries which often rely on the income which overseas visitors can bring.

The Oxitec solution provides a proven means of protecting people from dengue fever. It will enable individuals and whole communities to go back to work and get on with their lives free from this dangerous and debilitating disease. It will alleviate a major economic burden for governments around the world, and free up resources within communities to allow increased spending on other healthcare problems.

The Tiger mosquito or forest day mosquito, Aedes albopictus (Stegomyia albopicta), from the mosquito (Culicidae) family, is characterized by its black and white striped legs, and small black and white striped body. It is native to the tropical and subtropical areas of Southeast Asia; however, in the past couple of decades this species has invaded many countries throughout the world through the transport of goods and increasing international travel. This mosquito has become a significant pest in many communities because it closely associates with humans (rather than living in wetlands), and typically flies and feeds in the daytime in addition to at dusk and dawn. The insect is called a tiger mosquito because its striped appearance is similar to a tiger. Aedes albopictus is an epidemiologically important vector for the transmission of many viral pathogens, including the West Nile virus, Yellow fever virus, St. Louis encephalitis, dengue fever, and Chikungunya fever, as well as several filarial nematodes such as Dirofilaria immitis.

Oxitec Wants To Release Genetically Modified Mosquitoes Into Florida Keys

Mosquitoes aren’t just a pesky nuisance causing Floridians to claw at swollen welts on their limbs; they can also transmit deadly disease. Back in 2009, the Florida Keys suffered an outbreak of Dengue Fever, a fatal condition with flu-like symptoms, the first there since 1934.

Now a British biotech company Oxitec thinks they have the solution to avoiding future outbreaks: genetically modified mosquitoes. Their mutant skeeters not only glow red when placed under a microscope, they also carry a gene that causes new offspring to self-destruct.

In theory, Oxitec wants to release their GM male mosquitoes into the Keys so that they will mate with existing females and hatch larvae that won’t live long enough to bite people.

Many Key Westers are alarmed that a British biotech company wants to use their backyard for a genetic experiment. Resident Mila de Mier went as far as setting up an online change.org petition in April, which now has over 100,000 signatures of support.

“Nearly all experiments with genetically-modified crops have eventually resulted in unintended consequences…Why would we not expect GM (genetically modified) insects, especially those that bite humans, to have similar unintended negative consequences? Will the more virulent Asian tiger mosquito that also carries dengue fill the void left by reductions in A. aegypti? Will the dengue virus mutate (think antibiotic resistant MRSA) and become even more dangerous?”

In order to avoid a repeat of the 2009 outbreak, which lasted for 15 months and made 93 people sick, the Florida Keys Mosquito Control District spends upwards of a million dollars to blanket the chain of islands with pesticides.

As a Broward New Times cover story pointed out, Floridians may take current mosquito control measures for granted. In the days before the state’s extensive mosquito control programs, skeeter swarms in some areas were so dense “it was impossible to breathe without inhaling mouthfuls of mosquitoes.”

This isn’t the first time genetic engineering could be used to combat Dengue Fever. In 2010, Oxitec released 3 million mutant male mosquitoes into the Cayman Islands and report that within a year, the local population was cut by 80 percent.

If the Food and Drug Administration approves their “animal bug patent,” Oxitec will likewise release upwards of 10,000 GM mosquitoes at an undisclosed 36-square-acre block near the Key West Cemetery.

Oxitec admits their system isn’t foolproof. About one female is accidentally released for every 1,500 male mosquitoes, according to New Times, and it’s the females that bite and suck blood.

In April, the Florida Keys Environmental Coalition wrote to Gov. Rick Scott, asking him to stop Oxitec, pointing to the unknown consequences of being bit by one these rogue GM female mosquitos: “… biting female mosquitoes could inject an engineered protein into humans along with other proteins from the mosquitos’ salivary gland. Oxitec has yet to conduct or publish any study showing that this protein is not expressed in the salivary gland and therefore cannot be passed on to humans.”

As there haven’t been any reported cases of Dengue Fever in the Keys since 2009, residents are calling for more research to be done before introducing a brand new species into the local environment.

“We need more data. If something goes wrong the consequences could be catastrophic not only for humans but also the whole ecosystem, and I don’t want my family being used as laboratory rats for this.”
