Information on the latest subnational trends dates from December 10 for the three most affected countries (date of publication of the latest detailed WHO report). The three most affected countries (Guinea, Liberia, and Sierra Leone) report new cases distributed very unevenly across districts. At the national level, transmission is most intense in Sierra Leone, the country reporting the highest number of cases since the start of the epidemic (N=8,069). In Liberia, the number of new cases is decreasing, with all cases reported in 5 of the country’s 15 districts. In Guinea, the number of new cases has been generally stable for several weeks, though this stability masks a highly varied situation across districts.
