Amid an outbreak of Marburg virus in Rwanda, travelers coming into the United States who have been in Rwanda in the previous 21 days will be screened starting next week, the US Department of Health and Human Services announced Monday.

U.S. health officials are preparing to screen passengers flying in from Rwanda for symptoms of Marburg virus, a severe infection similar to Ebola.

The U.S. Centers for Disease Control and Prevention will issue its second-highest level of travel notice for Rwanda, recommending people to avoid nonessential travel due to the Marburg disease outbreak in the east African country,
