An outbreak of a rare type of Ebola in the DRC has killed 130 and infected hundreds more. What to know about the Bundibugyo virus, symptoms and how it spreads.

The director-general of WHO has also expressed deep concern “about the scale and speed of the epidemic” as reported deaths rise.

A hantavirus outbreak on a cruise ship raises concerns, but experts say the human-to-human Andes virus is inefficiently spread.

The unidentified person, who was working in the Democratic Republic of Congo, will be flown to Germany for treatment.

The hantavirus-stricken cruise ship MV Hondius arrived at its last stop Monday. Now, the waiting begins.

The United States restricted entry of people who have been to three African countries, after the World Health Organization declared a global health emergency. The outbreak has killed more than 100.

The ship at the epicenter of the hantavirus outbreak has been evacuated, and 16 Americans have now been transported to a specialized quarantine unit in Nebraska. Two are at a similar unit in Atlanta.

Most hantaviruses are not known to spread between people. Andes virus is the exception. After the initial spillover from infected rodents, it is the only hantavirus with well-documented person-to-person transmission.

That’s especially reassuring considering the seven U.S. passengers who got off the boat and flew home before the outbreak was flagged showed no symptoms during their travels, according to Dr. Jay Battacharya, acting director of the Centers for Disease Control and Prevention.
