Ebola Virus Disease (EVD)

  • The latest outbreak was declared in the Democratic Republic of Congo on 1 August 2018 in North Kivu and Ituri provinces. As of 26 August 2018, a total of 111 confirmed and probable EVD cases, including 75 deaths (case fatality ratio 67.6%), have been reported. Of the 111 cases, 83 are confirmed and 28 are probable. Of the 75 deaths, 47 occurred in confirmed cases. A total of 15 healthcare workers have been affected, of which 14 are confirmed and one has died.

  • Current Risk Assessment: This new outbreak is affecting north eastern provinces of the DRC, which border Uganda and Rwanda. Potential risk factors for transmission of EVD at national and regional levels include the transport links between the affected areas, the rest of the country, and neighbouring countries; the internal displacement of populations; and displacement of Congolese refugees to neighbouring countries and a long-term humanitarian crisis.

Additionally, the security situation in North Kivu may hinder the implementation of response activities. Based on this context, the public health risk is considered high at the national and regional levels and low globally. WHO recommends against the application of any travel or trade restrictions in relation to this outbreak. Source: WHO
