Ebola Survivor’s Antibodies Stop All Strains of the Virus, Study Finds

The Ebola virus launches an all-out barrage against the body, often killing victims within a week or two. It plays a nasty trick on the immune system, infiltrating cellular components normally used to sort and digest food and waste, known as endosomes and lysosomes. There, it’s able to hide from most antibodies that the body produces. Within this space it undergoes a change in shape that allows it to unload its genetic material and take over the cell. Researchers have now identified two antibodies from the blood of a survivor in West Africa that foils Ebola’s hide-and-shift act. These antibodies...

Ebola Outbreak Fueled by Incredibly Tiny Minority

(NEWSER) – Scientists are investigating minorities, but it's not how it sounds. So-called "super-spreaders" are a small group of people who, for whatever reason, turn out to be the major driver behind the spread of diseases, and scientists report in the Proceedings of the National Academy of Sciences that super-spreaders are more responsible for the Ebola epidemic in West Africa than previously thought. So far they know a few things; Ebola super-spreaders tend to be younger than 15 or in the 40-to-55 age range, for instance. In applying a mathematical model to cases in and near Freetown, Sierra Leone, researchers...

Fifth person dies in Guinea Ebola flare-up

A fifth person has died of Ebola in southeast Guinea since March 17, a health official told Reuters on Tuesday, raising concerns that a recent flare-up of the deadly virus could spread. The latest case was detected in Macenta prefecture, about 200 kilometers from the village of Korokpara where the four other recent Ebola-related deaths occurred, said Fode Sylla Tass, spokesman for National Coordination of the Fight against Ebola in Guinea. The man, who has not been identified, had recently visited Korokpara and had been in direct contact with the first patients, Tass said. He was buried in the village...

An innovative suitcase lab used to fight Ebola could help us untangle the Zika epidemic

The World Health Organization has declared Zika a global health emergency, because it believes the risks are high enough for a global response. And yet, we understand little about the virus and its effects on people. Zika’s links to neurological conditions, such as microcephaly—abnormal brain development in newborns—remain unproven. A team of Brazilian and African scientists (link in Portuguese) believe rapid and thorough testing for Zika will be key to solving that mystery. Given Brazil’s vast size and limited infrastructure, though, they’re having to deploy an inventive diagnostic tool to achieve that: A suitcase-sized laboratory. Since the beginning of the...
