The head of Africa’s top public health agency says that an outbreak of the Ebola-like Marburg fever in Rwanda is under control and that travel bans to the East African country are unnecessary.

The African CDC and Rwandan government objected to the Level 3 travel advisory issued by the U.S., saying Rwanda was being punished for its transparency.

Rwanda’s health minister says authorities are tracing every potential contact of the index case in the country’s outbreak of Marburg virus disease to reduce the risk of wider spread

A deadly, Ebola-like virus called Marburg is currently causing an outbreak in Rwanda. The country declared an outbreak of Marburg virus disease on Sept. 27 and has reported 58 confirmed cases and 13 deaths as of Oct. 8. Many of those who have been infected are health-care workers.

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.

The CDC has issued a Level 3 travel advisory for Rwanda due to an outbreak of the Marburg virus. The agency will also screen travelers from Rwanda.

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,

U.S. health officials announced Monday that all passengers flying from Rwanda to the United States will soon be screened for the Ebola-like Marburg virus.

The Marburg virus can cause a severe hemorrhagic fever that is similar to Ebola. And like Ebola, it can be deadly. This outbreak has included people in seven districts in Rwanda and by Tuesday, the number had risen to 36 people in isolation and treatment, many of them reportedly health care workers. Twelve people have died.

US official advice against non-essential travel to Rwanda in light of the outbreak of the deadly Marburg virus is “not fair”, Africa’s top health official Jean Kaseya has said. The head of the Africa Centres for Disease Control and Prevention (Africa CDC) added that it was “not the treatment Rwanda and Africa deserve”.
