Status: affected by circulating vaccine-derived poliovirus 2 (cVDPV2)

Three genetically-linked cVDPV2s were isolated from two acute flaccid paralysis (AFP) cases, with onset of paralysis on 26 and 27 May 2023, and one asymptomic community contact, from Fafi district, Garissa province.  Genetic sequencing confirms the isolated cVDPV2 are linked to cVDPV2 currently circulating in Banadir, Somalia.  The cases and community contact are all from Hagadera refugee camp, associated with frequent population movement with neighbouring Somalia.

Travel advice

WHO’s International Travel and Health recommends that all travellers to polio-affected areas be fully vaccinated against polio.
