Another Sudan Famine

faminesoudin

On 20 February 2017, the United Nations declared a famine in parts of former Unity State of South Sudan and warned that it could spread rapidly without further action. The World Food Programme reported that 40% of the South Sudanese population (4.9 million people) needed food urgently, and at least 100,000, according to the UN, were in imminent danger of death by starvation. UN officials said President Salva Kiir Mayardit was blocking food deliveries to some areas, though Kiir said on 21 February that the government would allow “unimpeded access” to aid organizations.

In addition, parts of South Sudan have not had rain in two years. According to United Nations Food and Agriculture Organization Representative Serge Tissot, “Our worst fears have been realised. Many families have exhausted every means they have to survive. The people are predominantly farmers and war has disrupted agriculture. They’ve lost their livestock, even their farming tools. For months there has been a total reliance on whatever plants they can find and fish they can catch.

The reports also warned that about 5.5 million people, half of South Sudan’s population, are expected to suffer food shortages and insecurity by July 2017. According to Jeremy Hopkins, the South Sudan representative for the UN children’s agency, more than 200,000 children are at risk of death from malnutrition in the country.

H7N9

I-RISE

Bird flu is back. Chinese authorities are closing live poultry markets as H7N9 courses through the country, infecting 192 and killing 79 in January alone.

So far, this strain of avian flu appears to have been transmitted only through contact with live poultry, but there’s always a fear it will mutate and start passing between humans. That’s what really scares experts: the possibility of a sudden change that triggers faster spread between humans and leads to a pandemic.

A disease doesn’t count as a pandemic until it spreads worldwide – Ebola killed more than 11,000 people across West Africa before it was brought under control, and that was just an epidemic. The most modern pandemics include the Spanish influenza, circa 1918 (as many as 50 million killed), and HIV/AIDS (35 million dead).

As Chinese officials attempt to stem the latest bird flu outbreak, global public health officials are racing to get ahead of what they call the next “big one”: a disease that will kill tens of millions. It’s all about preparedness, and a large part of that is spotting outbreaks early, so action can be taken to contain any situation before it spirals out of control.

It’s anyone’s guess when and where the next major epidemic – or pandemic – might emerge. It could be a mutated version of avian flu, or perhaps something completely unseen before, like the mysterious illness with Ebola-like symptoms that struck out of the blue in South Sudan last year.

Crimean-Congo haemorrhagic fever

When a patient in Madrid died last September of a disease called Crimean-Congo haemorrhagic fever, there was no shortage of headlines about the “new” deadly virus. But the disease has actually been around for years – it got the first part of its name when first reported in Crimea in 1944, and the second thanks to a 1969 spotting in Congo.

The last two words of the disease, abbreviated as CCHF, speak to the symptoms: fever, muscle aches, nausea, diarrhoea, bruising and bleeding (the list goes on), and eventually death in the second week of illness – about 30 percent of patients (sometimes more) succumb to the virus.

CCHF is found pretty much everywhere south of the 50th parallel north: Africa, the Balkans, the Middle East, and Asia. Humans tend to contract the virus through contact with the blood of an infected animal (itself having been bitten by infected ticks) – vets, people working in slaughterhouses, and farmers are typically most at risk.

Once in humans, the virus can be spread through contact with blood, secretions, bodily fluids, and the like. It has been contracted in hospitals thanks to poor sterilisation of equipment and reuse of needles.

The virus bothers researchers and doctors for a number of reasons, one of them cultural: it’s endemic in some Muslim countries where large-scale animal slaughter is part of celebrating (and feasting) for the holiday of Eid al-Adha.

Doctors in Pakistan, for example, have warned of a potential health catastrophe unless slaughtering practices change, as the feasting holiday will be in the summer for the next 10-15 years, coinciding with tick season and CCHF prevalence.

There are similar concerns in Afghanistan, where public health officials have been warning the public about using gloves and other protective clothing when handling animals.

There is no vaccine for Crimean-Congo, and there is no cure, although antiviral drugs have shown some promise. Nipah virus Tackling drought with emergency aid is not the answer

This one’s got a Hollywood hook: The 2011 film Stephen Soderbergh film Contagion is reportedly based on it. Spoiler alert. In the movie, Nipah causes a global pandemic. In reality, we’re far from that.

But the way Nipah got going in real life is paralleled in the film: Thanks to drought, deforestation and wildfire, large fruit bats that carry the virus found their natural habitats in Malaysia destroyed. So they moved to fruit trees that happened to be in fairly close proximity to pig farms.

The pigs ate fruit contaminated by bat urine and saliva, the virus spread quickly among livestock, and again farm workers were the first hit. This first outbreak in Malaysia in the late 1990s saw the country cull more than one million pigs: a major hit to the economy.

In its first appearance, Nipah killed 105 of 256 known infected people.

But humans can also get Nipah by drinking raw palm date sap, a delicacy in Bangladesh. It is believed to be the cause of regular seasonal outbreaks in that country. When the sap is harvested, it has already been infected by bats in the trees.

Nipah scares researchers because it kills quickly – nausea, fever, and vomiting, patients progress to a coma within 24-48 hours, and then die. It has also spread swiftly from rural areas to cities.

Once in humans, the virus is found in saliva, so it can kill caregivers and family members who share utensils and glasses, or hug and kiss their sick family members. Middle East Respiratory Syndrome (MERS)

Bandied about as the next pandemic possibility for a while, MERS was first reported in Saudi Arabia in 2012, although looking back researchers believe there were cases the same year in Jordan.

It’s deadly – a reported 36 percent of patients die – and looks to have come to humans via bats, again. There’s a pattern here: Bats carry a long list of killer viruses and likely triggered the Ebola outbreak as well as SARS and others.

MERS causes fever, cough, shortness of breath, and in more than one third of patients, death. A 2015 outbreak in South Korea killed 36, and caused serious panic. Thousands of schools were closed, and many businesses were hit hard as people were wary even of going outside, and many others were quarantined.

While MERS is deadlier than its cousin SARS, it is also less contagious. It is spread through close contact with an infected person, and most transmissions have been in healthcare settings. There’s no real evidence that it’s gone airborne – that’s always a major fear – but the possibility hasn’t been completely ruled out.

For now, there’s no reason to panic about MERS, but it’s always a worry during the annual Hajj pilgrimage to Muslim holy sites in Saudi Arabia, which sees some two million people converge in the country with the most cases.

Like the other diseases mentioned here, there’s no vaccine and there’s no treatment – it’s all about hygiene.

There are plenty of other scary killers out there, and researchers are both tracking the movement of viruses between species and attempting to figure out a key plot point: why exactly a virus goes airborne. One last top tip: keep a particular eye on influenza. It’s not exotic and everyone knows its name, but some form of the flu could easily become the next “big one”. Oh yes, and be careful of bats.

Largest DP Camps in the World

kakuma

The legacies of today’s conflicts can be seen in the enormous populations of the world’s largest displaced persons’ camps. For most these camps are far from a temporary home. With scarce local resources, the majority of the camps depend on external aid for survival.

10. Tamil Nadu State, India
An estimated 66,700 Sri Lankans currently reside in this refugee camp. Another 34,000 live outside of the camp.

9. Nyarugusu, Tanzania
This camp is home to an estimated 68,197 refugees. Nearly two-thirds are children between the ages 10-24. Almost all of them were born in the camp or became a refugee at a very young age. The majority of the refugees are Burundians and Congolese.

8. Nakivale, Uganda
As one of Africa’s oldest and largest refugee camps, Nakivale currently houses 68,996 people. Many of the residents fled the violent conflict in the Democratic Republic of the Congo. It is unlikely the refugees will be able to return home in the near future.

7. Yida, South Sudan
This refugee camp is home to 70,736 registered individuals. After a sharp increase in registrations in February, the number of new registrations is slowly decreasing.

6. Mbera, Mauritania
UNHCR is predicting there to be 75,261 residents in this camp by December 2014. The majority of the refugees are from Mali, but many come from the Democratic Republic of the Congo and Cote d’Ivoire, as well. It is expected the influx of Malian refugees will slowly stabilize. The situation in Mali still remains delicate and will not allow for large-scale returns.

5. Al Zaatari, Jordan
UNHCR reports there are 101,402 refugees currently in the camp and that number has been decreasing since February 2014. The majority of the refugees are Syrians fleeing the violence in their country. The camp has faced several violent protests since it opened two years ago, mainly due to poor living conditions.

4. Jabalia, Gaza Strip
The largest of the Gaza Strip’s eight refugee camps, Jabalia is home to 110,000 registered refugees who fled from southern Palestine. The camp faces extreme unemployment, as well as a contaminated water supply and electricity cuts.

3. Kakuma, Kenya
This refugee camp has been home to South Sudan refugees since 1992. The ongoing violence in South Sudan has prompted 20,000 people to flee to Kenya as of February 2014. Today, 124,814 refugees from 15 nationalities live in Kakuma. The camp is significantly over capacity and suffers from lack of resources.

2. Dollo Ado, Ethiopia
This camp holds 201,123 registered Somali refugees. The population of this refugee camp has been steadily increasing since March 2013 due to drought and famine in Somalia.

1. Dadaab, Kenya
UNHCR estimates that in December 2014 there will be 496,130 refugees in the camp from Ethiopia, Somalia, South Sudan and various other places. They also estimate there to be 83, 660 people seeking asylum from the Democratic Republic of the Congo, Ethiopia and South Sudan
