A severe Ebola outbreak in the Democratic Republic of Congo has claimed more than 100 deaths and infected over 390 people, officials said after the World Health Organization classified the crisis as an international emergency. The outbreak, caused by the Bundibugyo strain for which no vaccine or treatment exists, is concentrated in the eastern Ituri province.

Health authorities in the U.S. reported that six American citizens have been exposed to the virus while in Congo. One of the Americans reportedly shows symptoms, while three others were identified as high‑risk contacts. The Centers for Disease Control and Prevention confirmed that a small group of Americans is being safely withdrawn, though the agency has not disclosed the exact number. U.S. officials are arranging transport for the group to a secure quarantine facility, possibly in a military base in Germany, and are coordinating with airlines for contact tracing and increased testing.

The CDC has declared the risk to the United States low but has implemented several precautionary measures. These include monitoring travelers from affected regions, imposing entry restrictions on non‑U.S. passport holders who have recently been in Congo, Uganda or South Sudan, and enhancing hospital readiness. In addition, the U.S. government has issued a Level 4 travel advisory, the highest alert, urging citizens to avoid travel to the affected country.

The outbreak has spilled over into neighboring Uganda, where two cases have been confirmed, including one death. Regional health ministries are working with the WHO to conduct cross‑border screenings and strengthen surveillance. Rwanda has tightened border checks with Congo, while Nigeria closely monitors the situation.

With no approved countermeasures, public health experts emphasize strict adherence to infection‑control protocols, especially during funeral rites, which historically amplified earlier Ebola spread.
