The last confirmed non-sylvatic case had symptom onset on 12 July.

A new confirmed, sylvatic case was reported from Lingomo Health Zone in Tshuapa province.

16 probable cases are under investigation (4 in Kinshasa, 8 in Kwango, and 1 case each in Bas Uele, Kwilu, Lualaba and Sud Ubangi provinces).

The reactive vaccination campaigns in Feshi Health Zone in Kwango province is ongoing and will begin shortly in Mushenge Health Zone in Kasai province.


The continuing detection and investigation of probable (including the 42 probable cases in Angola) and sylvatic cases demonstrate that active surveillance is ongoing. Nevertheless, it is important to note persistent difficulties in surveillance and laboratory confirmation capacities, which may delay case detection. A strong and sustained surveillance effort remains crucial.

The status of the probable cases in Angola will be reviewed by the Ministry of Health’s Final Classification Committee once the investigations are completed on their exposure history and yellow fever vaccination status.
