Among the confirmed cases, 68% are males, and 45% are adults between 30 and 39 years of age. Health workers from two health facilities in Kigali account for almost 80% of all confirmed cases. Most cases are reported from the three districts of Kigali city.
The highest number of confirmed cases (61) were reported in the first three epidemiological weeks (week 39-41) of the outbreak. This was followed by a sharp decline, with three or less cases reported between epidemiological week 42 (14 to 20 October), and 44 (28 October to 3 November).
