Somalia is responding to concurrent outbreaks of circulating vaccine-derived poliovirus type 2 and type 3. The type 2 virus (cVDPV2) was first detected in environmental sampling in October 2017 in Banadir region, prompting large-scale outbreak response activities, including enhanced surveillance for other undetected polioviruses. In February 2018, an outbreak of cVDPV type 3 was confirmed following its isolation from environmental samples also in Banadir region. Outbreak response activities for both strains of poliovirus are ongoing.
