On 6–7 August, the World Health Organization (WHO) convened a meeting in Freetown, Sierra Leone, to discuss how to establish a biobank for up to 100,000 samples of blood, semen, urine and breast milk from confirmed and suspected Ebola patients, as well as swabs taken from the bodies of people who died from the virus. Held by health agencies in both West Africa and the West, the samples could be valuable in understanding how the current Ebola crisis evolved, preparing for future outbreaks and developing public-health research capacity in a region that depends on outside experts.

A highly contagious strain of avian flu is spreading across West Africa, decimating poultry farms and stoking fears the virus will jump from birds to humans, the U.N.'s food agency warned on Monday.

Markets and farms in Nigeria, Burkina Faso, Niger, Ivory Coast and Ghana have been hit with the deadly H5N1 virus over the past six months, the U.N.'s Food and Agriculture Organization (FAO) said.

If the virus continues to spread, it could affect more than 330 million people across West Africa, hurting food security and human health in a region still recovering from the Ebola crisis.

"Urgent action is needed to strengthen veterinary investigation and reporting systems... to tackle the disease at the root, before there is a spillover to humans," Juan Lubroth, head of the FAO's animal health division, said in a statement.

Abstract

International air travel has already spread Ebola virus disease (EVD) to major cities as part of the unprecedented epidemic that started in Guinea in December 2013. An infected airline passenger arrived in Nigeria on July 20, 2014 and caused an outbreak in Lagos and then Port Harcourt. After a total of 20 reported cases, including 8 deaths, Nigeria was declared EVD free on October 20, 2014. We quantified the impact of early control measures in preventing further spread of EVD in Nigeria and calculated the risk that a single undetected case will cause a new outbreak. We fitted an EVD transmission model to data from the outbreak in Nigeria and estimated the reproduction number of the index case at 9.0 (95% confidence interval [CI]: 5.2-15.6). We also found that the net reproduction number fell below unity 15 days (95% CI: 11-21 days) after the arrival of the index case. Hence, our study illustrates the time window for successful containment of EVD outbreaks caused by infected air travelers.

Set of graphs on the Ebola Outbreak

The outbreak continues to claim lives, but Liberia could be confirmed Ebola free on May 9th. The situation in Guinea and Sierra Leone is also improving with fewer provinces reporting cases than in previous weeks. The World Health Organisation reports that each country now has enough treatment beds to be able to isolate and treat patients with Ebola, and to bury everyone known to have died of the disease.

The chart above shows numbers from both the WHO's regular situation reports and from patient databases, which tend to be more accurate but are less complete for recent weeks.
