The World Health Organization announced that the number of suspected Ebola cases has dropped to 116 after hundreds of potential cases were ruled out through testing and investigation.

The Africa Centres for Disease Control and Prevention declared an outbreak of the Bundibugyo strain of Ebola in the Democratic Republic of Congo on May 15. This marks the country's 17th Ebola outbreak since the virus was first identified in the region.

Health officials have been working to identify and test suspected cases as part of containment efforts. The reduction in suspected cases suggests that initial concerns about the scope of the outbreak may have been higher than the actual number of infections.

The Bundibugyo strain is one of several species of Ebola virus that can cause severe hemorrhagic fever in humans. Previous Ebola outbreaks in the Democratic Republic of Congo have varied significantly in size and duration, with some contained relatively quickly while others have spread more extensively.

International health organizations continue to monitor the situation and provide support for containment measures in the affected region.
