May 17 (Reuters) - The World Health Organization (WHO) on Sunday declared the Ebola outbreak affecting eastern Democratic Republic of Congo (DRC) and Uganda a public health emergency of international concern.

The outbreak is caused by the Bundibugyo virus. Unlike Ebola‑Zaire strains, Bundibugyo currently has no approved virus‑specific therapeutics or vaccines, making the situation especially concerning for health authorities.

As of Saturday, health officials reported 80 suspected deaths, 8 laboratory‑confirmed cases, and 246 suspected cases in Ituri province in eastern DRC, spanning at least three health zones: Bunia, Rwampara and Mongbwalu. The DRC health ministry had earlier reported the 80 suspected deaths.

The WHO warned the outbreak could be substantially larger than current counts indicate given a high positivity rate in initial samples and a rising number of suspected cases. The agency said some instances of international spread have already been documented.

Confirmed cases have been reported outside Ituri: two apparently unrelated laboratory‑confirmed cases — including one death — were recorded in Kampala, Uganda, in people who had travelled from the DRC; a laboratory‑confirmed case was also detected in Kinshasa from a person returning from Ituri.
WHO recommendations: Immediately isolate confirmed cases; monitor contacts daily; restrict national movement and prohibit international travel for contacts until 21 days after exposure unless a medical evacuation is required. Countries sharing land borders with the DRC should activate emergency and disaster‑management systems and step up cross‑border and main‑road screening.
The WHO cautioned against blanket border closures or trade restrictions, saying such measures can drive movement into informal, unmonitored crossings and worsen transmission risks. Instead, the agency urged targeted surveillance, rapid testing, safe patient isolation, and coordinated cross‑border public health operations.
