In response to an unprecedented outbreak of Marburg virus in Rwanda, the Centers for Disease Control and Prevention now plan to screen arriving international travelers for their risk of bringing the deadly Ebola-like disease into the country.

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.

There are no treatments or vaccines approved for Marburg, a virus in the same family as Ebola with a fatality rate between 24% to 88%.
