  • In Madagascar, a circulating vaccine-derived poliovirus type 1 (cVDPV1) has been confirmed. The virus was isolated from one case of acute flaccid paralysis (AFP) with onset of paralysis on 29 September, and from three healthy contacts. An estimated more than 25% of children remain under-immunized against polio in the country. Madagascar was previously affected by a cVDPV2 outbreak in 2001/2002 (resulting in five cases) and in 2005 (resulting in three cases). Emergency outbreak response is being finalized, with campaigns to be held in December and January.
