By focusing on the end of the epidemic, writes infectious disease specialist Nahid Bhadelia, we miss the larger point.

Guinea was declared free of Ebola on Tuesday after more than 2,500 people died from the virus in the West African nation, leaving Liberia as the only country still awaiting a countdown for the end of the epidemic. People in the capital, Conakry, greeted the declaration by authorities and the U.N. World Health Organization with mixed emotions given the deaths and the damage the virus did to the economy and the country's health and education sectors.

The epidemic has waned, but the virus still threatens the lives of women and children in West Africa. By Matt Hongoltz-Hetling.

It was around 3 in the afternoon when Sherdrick Koffa spotted, in neatly written script, the name on the body bag that he was preparing to set ablaze. It was the name of a classmate. The two grew up together, had played together as children. Now, only a few days into his job burning the Ebola dead, work that had already estranged Mr. Koffa from his family, he was expected to burn the body of his friend.

"If there's anything that this outbreak has taught me, it's that I'm often wrong," says Dr. Daniel Bausch. He's talking about Ebola. He's one of the world's leading experts on the virus — an infectious disease specialist at Tulane University and a senior consultant to the World Health Organization. And as he makes clear, he's still got a lot to learn.

Months after a male Ebola survivor tested negative for the disease, he transmitted the deadly virus to a female partner through unprotected sex, a genetic analysis revealed. The Liberian woman, who became ill with the disease and died in March, is the first person known to contract the Ebola virus from sex, researchers reported this week in the New England Journal of Medicine.

Ebola persists in the semen of male survivors much longer than previously thought, a study shows. The report in the New England Journal of Medicine found two-thirds of men had Ebola in their semen up to six months after infection, and a quarter after nine. A separate study, in the same journal, reports Ebola being spread through sex with a survivor six months after their symptoms had started.

A Scottish nurse infected with Ebola in Sierra Leone last year is now back “in a serious condition” nine months after doctors said she had made a full recovery. Although the exact nature of the condition has not been reported, Pauline Cafferkey’s doctors have detected the Ebola virus and moved her to a specialist isolation unit in London.

No one knows what caused the Plague of Athens—but to discover the source of an outbreak millennia after the fact, scientists need victims’ remains and a bit of luck.

Was the Ebola vaccine 100% effective, or 100% lucky? The good money is on a percentage somewhere in between, but in truth, we will never know. For three reasons, we cannot know if the vaccine really worked, or how well. Those reasons are the lack of placebo comparison, the way the investigators diagnosed vaccine failure and the possibility of statistical flukes.

LONDON (Reuters) - Thousands of West Africans who were infected with the Ebola virus but survived it are suffering chronic conditions such as serious joint pain and eye inflammation that can lead to blindness.

A vaccine against the deadly Ebola virus has led to 100% protection and could transform the way Ebola is tackled, preliminary results suggest. There were no proven drugs or vaccines against the virus at the start of the largest outbreak of Ebola in history, which began in Guinea in December 2013. The World Health Organization (WHO) said the findings, being published in the Lancet, could be a "game-changer".

The vaccine was 100 percent effective when it was tested on more than 4,000 people who were in close contact with Ebola patients in the African nation of Guinea, according to a study published today in the Lancet medical journal. The trial of the vaccine, called Ebola ca Suffit -- “Ebola, that’s enough” in French -- began on March 23.

Health officials leading the fight against Ebola in Sierra Leone say fear, fatigue and denial are allowing the virus to spread.

Ebola survivors’ immune systems now make antibodies to the virus. Those antibodies are, essentially, the ideal medicine. By Erica Check Hayden.
