Circulating vaccine-derived poliovirus type 2 – Syrian Arab Republic

A circulating vaccine-derived poliovirus type 2 (cVDPV2) outbreak has been confirmed in the Deir Al Zour Governorate of the Syrian Arab Republic. There is evidence of genetic linkage among three isolates of type-2 vaccine-derived polioviruses (VDPV2) isolated in the stool specimens of two acute flaccid paralysis (AFP) cases with dates of onset of paralysis on 5 March and 6 May 2017, and the contact specimen of an AFP case collected on 17 April 2017. Al Mayadeen was also the epi-centre of the wild poliovirus type 1 (WPV1) outbreak in Syrian Arab Republic in 2013. Aggressive multi-country polio outbreak response effectively controlled the WPV1 outbreak and no WPV1 case has been reported in Syrian Arab Republic since 21 January 2014.
