Status: imported poliovirus

Kenya is one of the countries in the “wild poliovirus importation belt” – a band of countries stretching from west Africa to central Africa and the Horn of Africa, which are recurrently re-infected with imported poliovirus. The immediate priority is to stop all active outbreaks using mop-up campaigns with oral polio vaccine in the infected areas, combined with a series of large-scale, synchronized supplementary immunization activities across most of the “importation belt” countries to protect against further importations.

Polio campaign monitoring in Kenya


Polio this week in Kenya

  • No new WPV cases were reported in the past week. The most recent case in the region had an onset of paralysis on 5 January, from Somali region in Ethiopia. It is the first and only case in the Horn of Africa in 2014.
  • The total number of WPV1 cases in the Horn of Africa is 218 since the beginning of the outbreak in April 2013 (194 from Somalia, 14 from Kenya and ten from Ethiopia).
  • Outbreak response across the Horn of Africa is continuing. Recommendations from the recently held Horn of Africa Technical Advisory Group (TAG) are now actively being incorporated into outbreak response planning. The TAG had underscored that the initial response to the outbreak was appropriate, however expressed grave concern that gaps in SIA quality and surveillance remained in key infected areas of the region.
  • In particular, the TAG expressed concern at critical quality gaps in implementation in key areas of Ethiopia. The group recommended that infected countries should focus efforts on high-risk and infected areas, by conducting high-quality SIAs no more than four weeks apart.
