Situation Update

  • Circulating vaccine-derived poliovirus type 2 (cVDPV2) and type 3 (cVDPV3) have been confirmed in Somalia. Two cases of cVDPV2 and three cases of cVDPV3 have been confirmed, one of which is confirmed as having co-infection of cVDPV2. The total number of cases is four.
  • cVDPV3 has been isolated from samples collected from contacts in Bulo-Burte (Hiran region) and Warsheikh (Middle Shebelle) and from healthy children sampling in Jamamme West (Lower Juba).
  • Environmental surveillance continues to detect cVDPV2 and cVDPV3 in samples collected from four sites in Banadir (Mogadishu) region. cVDPV2 was first detected in Somalia in December 2017 in environmental samples. In March 2018, VDPV2 was detected in the environment in neighbouring Nairobi.
  • An mOPV2 vaccination round reaching almost 700,000 children under five in six partially-accessible and accessible regions of Somalia has been completed. This is the first of two additional rounds utilising mOPV2 in response to the continued detection of cVDPV2, synchronized with border areas of Kenya and Ethiopia. Post campaign independent monitoring has reported that all of six regions of Somalia targeted in this campaign had 90% or more vaccination rates in accessible areas.
  • A targeted immunization campaign using bivalent oral polio vaccine (bOPV) is ongoing this week in Banadir, Lower Shabelle and Middle Shabelle regions.
  • WHO and UNICEF are working closely with the Government of Somalia to support the outbreak response in country and to coordinate on border areas involved in sub-regional outbreak response activities.
