Outbreak briefing

As of June 12, 2026, two active outbreaks are being monitored globally. The lead outbreak is the Ebola disease caused by Bundibugyo virus, which is currently affecting two countries, the Democratic Republic of the Congo and Uganda. This outbreak has reported 534 confirmed cases, 1 probable case, and 93 deaths. The second lead outbreak is a Hantavirus outbreak linked to cruise ship travel, affecting eight countries and reporting 11 confirmed cases, 2 probable cases, and 3 deaths.

The ongoing Ebola outbreak in the Democratic Republic of the Congo and Uganda, as well as the Hantavirus outbreak with international travel connections, warrant close surveillance attention. Authorities and journalists should continue to monitor these outbreaks, particularly in the Democratic Republic of the Congo, Uganda, and countries with reported Hantavirus cases.
