The finding of the Ebola-like disease, which killed a man in Guinea, has prompted public health measures.

Genetic analyses suggest that the virus came from a patient who survived the 2013–2016 West African outbreak.

A study of people in Sierra Leone suggests that the virus can lie in hiding from the immune system before re-emerging later and sparking a new response—although researchers didn’t examine whether this could make people infectious again.

A wildlife camera trap survey of critically endangered West African lions finds they have no preference for parks over trophy-hunting areas, possibly because of poor habitat quality in the no-hunting zones.

The Bombali Ebola virus was identified in bats in Sierra Leone, and there’s no evidence that it has infected people or causes human disease.

A public-health nonprofit and an international drugmaker team up to stockpile hundreds of thousands of doses of a promising vaccine and to speed along the approval process.

Field tests fail to show improved prognosis for Ebola-infected patients treated with survivors’ blood plasma.

As the number of Ebola cases declines, Chimerix is unable to recruit enough patients for its trial in Liberia testing the antiviral drug brincidofovir.

The epidemic in West Africa may have been sparked by bats in Guinea, researchers propose, but concrete evidence of the route of zoonotic infection is lacking.

Researchers will test antiviral drugs and transfusions of blood from Ebola survivors in the West African countries hardest hit by the epidemic.
