Marburg Outbreak Reported In Uganda, Complicating Ebola Response

"The outbreak is said to be localized"

"Uganda formally reported to the World Health Organization on Tuesday that it had detected a Marburg disease outbreak in the western part of the country, a spokesperson for the Geneva-based global health agency told STAT. The development could further complicate the effort to contain what is already the third-largest Ebola outbreak on record in Central Africa. Both diseases are viral hemorrhagic fevers.

The Ugandan government has not yet publicly disclosed a Marburg outbreak. But the U.S. embassy in the Ugandan capital, Kampala, issued a health alert on Monday, saying it had been made aware of a possible case of Marburg in the country. The alert was a level 4 advisory alerting Americans they should not travel to Uganda.

The notification from Uganda to the WHO was of a single case. But a well-placed source — who answered questions from STAT on the proviso that their name and place of work would not be identified — said that Uganda had actually detected two cases of Marburg as of Monday. The individual said it appeared that at this point, the outbreak is localized."
