Viral Hemorrhagic Fevers

Viral hemorrhagic fevers (VHFs) are a group of diseases that are caused by several distinct families of viruses. Ebola and Marburg diseases are both VHFs. 

On January 29, 2025, the Ministry of Health of Uganda officially declared an Ebola outbreak caused by the Sudan virus in the nation’s capital, Kampala. This is the eighth Ebola outbreak in Uganda since 2000. Currently, no suspected, probable, or confirmed Ebola cases related to this outbreak have been reported in the United States, or outside of Uganda. CDC has issued a Travel Health Notice Level 2: Practice Enhanced Precautions for people traveling to Uganda.

On January 14, 2025, the World Health Organization issued a notice of a Marburg outbreak in the Kagera region in northwest Tanzania, which includes nine cases and eight deaths. Marburg is a rare but severe hemorrhagic fever, similar to Ebola virus disease, that can cause serious illness and death. Currently, there are no cases of Marburg reported in other African countries or the United States, and the risk of infection with this virus in the U.S. is low. CDC has issued a Level 1 Travel Health Notice for persons traveling to Tanzania.
