Current Situation

Cases in the most affected countries

  • A total of 33 confirmed cases of Ebola virus disease (EVD) was reported in the week to 26 April. Two areas, Forecariah in Guinea and Kambia in Sierra Leone, accounted for 25 (76%) of all confirmed cases reported. Improved community engagement in these areas is required to ensure that all remaining chains of transmission can be tracked and ultimately brought to an end.
  • Guinea reported 22 confirmed cases in the week to 26 April, compared with 19 cases the previous week. Sierra Leone reported 11 confirmed cases, compared with 12 cases the previous week. Liberia reported no confirmed cases for the fifth consecutive week. Of 55 districts in Guinea, Liberia, and Sierra Leone that have reported at least one confirmed case of EVD since the start of the outbreak, 39 have not reported a case for over 6 weeks.
  • A total of 5 Guinean prefectures reported at least one confirmed case in the week to 26 April. No cases were reported from the capital, Conakry. The vast majority of cases (17 of 22: 77%;) were reported from the western prefecture of Forecariah, which borders the Sierra Leonean district of Kambia.
