Current Situation

Cases in the most affected countries

  • There were 12 confirmed cases of Ebola virus disease (EVD) reported in the week to 24 May: 9 from Guinea and 3 from Sierra Leone. A total of 5 districts (3 in Guinea, 2 in Sierra Leone) reported at least one confirmed case, compared with 6 districts the previous week. The west-Guinean prefecture of Forecariah reported the most cases of any one district, and continues to present the greatest challenge in terms of response, with multiple chains of transmission over a wide geographical area (4 sub-prefectures), and the continued occurrence of cases from unknown sources of infection.
  • Cases from Guinea were reported from the western prefectures of Dubreka (3 cases) and Forecariah (5 cases), with a single case reported from the north-western prefecture of Boke, which borders Guinea-Bissau. In line with the previous week, cases in Boke and Dubreka were concentrated in the sub-prefectures of Kamsar and Tanene, respectively. The 5 cases reported from Forecariah were reported from 4 different sub-prefectures. A 4-day targeted case-finding and sensitisation campaign concluded in Forecariah on 19 May. During the course of the campaign multidisciplinary teams trained in case detection and social mobilisation visited 8023 homes, and contacted 38 557 people.
