  • A case of vaccine-derived poliovirus type 2 (VDPV2) has been reported with onset of paralysis on 20 July 2015 in Bamako city, Mali. The virus was isolated from a 19-month old boy of Guinean nationality. The closest genetic match to this case is from a case from Kankan, Guinea, with onset of paralysis on 30 August 2014. The genetic changes suggest that the cVDPV2 has been circulating for more than 12 months. Discussions are currently ongoing with national health authorities to plan and implement an urgent outbreak response.
