Sierra Leone’s Minister of Health declared an mpox outbreak in January. By May the country had responded to more than 2,100 cases and 11 people had died from the painful disease, which can cause fever, rash and swollen lymph nodes, and is particularly dangerous for individuals who are immunocompromised. A Task Force team has been working closely with the government to help shore up the response.
SONAR (Strengthening Outbreak Notification And Response) – an initiative of The Global Fund that is implemented by The Task Force for Global Health, in partnership with Africa CDC and the World Health Organization – is working with the Sierra Leone Ministry of Health to strengthen surveillance for early detection and reporting, real-time data analysis, and dissemination of epidemiological communication products (epidemiological reports and mpox situation reports) to inform decision-making by public health authorities. Sierra Leone is one of 13 countries where SONAR is active.
