Between 23-27 September,  two cases were laboratory confirmed for Neisseria meningitidis serogroup W135  in Cankuzo province, in a commune bordering Tanzania.  To date, only serogroup A had been identified in 53 samples from all affected provinces. Systematic sampling of suspected cases is ongoing  in order to detect whether there has been a shift  in the dominant serogroup from A to W135. In the meantime, the vaccination campaign with the current polysaccharide bivalent vaccine ( for serogroups A and C) will continue in the affected provinces.
