With millions of pigs killed due to a major outbreak of African swine fever virus in Asia, researchers have intensified efforts to find a vaccine quickly.

Understanding how domestic pigs can be infected with the deadly virus could be key to protecting them from it.

African swine fever virus has left the continent on three occasions, causing outbreaks in Europe, the Americas, and most recently, East Asia.

A devastating outbreak of the virus across East Asia has made the long-neglected pathogen a top research priority, but many challenges lie ahead.

A study of 16,000 people suggests that human herpesvirus 6A is a risk factor for developing multiple sclerosis, reinvigorating a neglected hypothesis that the virus could be involved in triggering the disease.

The virus, which has sickened at least 59 people, does not appear to transmit easily between humans.

Scientists are using social media to track diseases and understand how people respond to them.

A group of epidemiologists and computer scientists built a system to mine various online sources for keywords suggesting disease outbreaks.

Health officials are rushing a genetically engineered product into the field to counter uncontained outbreaks of vaccine-derived polio.
