    Ebola vaccine performs well in U.K. human trial

    An Ebola vaccine candidate developed by GlaxoSmithKline and the National Institutes of Health effectively jump-starts the immune system with few side effects, researchers report January 28 in the New England Journal of Medicine.

    The vaccine is based on a chimpanzee cold virus, called adenovirus 3 (ChAd3), that’s been engineered to produce a viral protein specific to the Zaire Ebolavirus...

    Year in review: Science faces Ebola epidemic


    West Africa’s 2014 Ebola epidemic demonstrated what can happen when a contagious virus emerges amid a population served by a broken medical system, and where cultural practices, public fears and porous borders fuel the spread of disease.

    The outbreak also...

    Ebola vaccine shows no major side effects in small study

    Guest post by Nathan Seppa

    An experimental vaccine against Ebola virus has tested well in people, researchers report.

    The vaccine uses a chimpanzee common cold virus that cannot replicate to deliver an Ebola protein that doesn’t cause infection. Combined, the virus and protein trigger an immune reaction.

    When 20 healthy adults received vaccine shots, their immune systems...

    Genes influence Ebola’s impact

    Surviving or succumbing to Ebola may depend on a person’s genes.

    After infection with the deadly virus, an individual’s genetic makeup could determine how hard Ebola hits — and whether it triggers the disease’s brutal bleeding, a study in laboratory mice suggests.

    The group of mice used in the study is the first to mimic the spectrum of symptoms seen in humans and may offer...

    Ebola virus edits its own genetic material

    As it invades a host cell, the Ebola virus edits its genetic material, adding extra RNA building blocks. These changes may produce new proteins that scientists have not yet described, which in turn may affect how the virus grows in animals and humans. Studying the proteins in greater detail may lead to better treatments for Ebola in the future, scientists suggest November 4 in mBio...

    Ebola continues rapid spread in West Africa

    Ebola has now infected about 9,000 people and killed nearly 4,500, including 263 health care workers, the World Health Organization reported Wednesday. These numbers are probably an underestimate, WHO officials said.

    Disease transmission is still rampant in Liberia, Guinea and Sierra Leone, although in some parts of those countries the number of new cases is falling. Those improvements...

    Dallas health worker is first to catch Ebola in U.S.

    Guest post by Lila Guterman

    A female health care worker in Dallas has tested positive for Ebola, officials announced Sunday. The health care worker is the first to have caught the virus in the United States. She had cared for the first patient diagnosed with Ebola in the country. He had contracted the virus in Liberia and then traveled to Texas in September. He died October 8.

    First Ebola patient diagnosed in U.S. dies

    Guest post by Tina Hesman Saey

    The first person diagnosed with Ebola in the United States has died.

    Thomas Eric Duncan, who contracted the virus in Liberia and fell ill four days after traveling to Dallas, was reportedly being treated with an experimental drug called brincidofovir at Texas Health Presbyterian Hospital in Dallas. He died October 8 at 7:51 a.m. Central time, a ...

    Ebola case identified in Dallas

    Guest post by Nathan Seppa

    The first case of Ebola virus to be diagnosed in the United States was announced September 30 in Texas. In a press briefing, CDC director Tom Frieden said that a man flying on a commercial jet left Liberia in good health on September 19 and arrived in the United States the next day. On September 24, he began showing symptoms of illness, sought care two days...

    More than 1 million Ebola cases may hit West Africa by January

    The Ebola epidemic in West Africa could cause more than 1 million casualties unless improved isolation and treatment of patients are put in place, new projections of the outbreak suggest. Without drastic improvements, weekly cases of Ebola should increase from hundreds to thousands, World Health Organization officials and others report in the New England Journal of Medicine September 23. In...
