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 this week in Kenya

  • No wild poliovirus type 1 (WPV1) cases have been reported in the past week. No cases have been reported in 2015. The total number of WPV1 cases that were reported in the Horn of Africa in 2014 was 6: 1 in Ethiopia (date of onset of paralysis on 5 January) and 5 in Somalia. The most recent case, which had onset of paralysis on 11 August 2014, was from Hobyo district of Mudug province, central Somalia.
  • No cases of type 2 circulating vaccine derived poliovirus (cVDPV2) have been reported in the past week. No cases have been reported in 2015. In 2014, 2 cases were reported in South Sudan. The most recent case of cVDPV2 had onset of paralysis in South Sudan on 12 September.
  • The outbreaks in Ethiopia and Kenya were closed last month, with an assessment team determining that transmission has stopped. Strong surveillance is central to close any outbreak, enabling confidence that the virus is truly absent. Read more.
  • Subnational Immunization Days (SNIDs) are planned in Somalia for August, with dates to be confirmed. In September, National Immunization Days are planned in Djibouti, Eritrea, Somalia and Yemen, and SNIDs in Ethiopia, Kenya and Uganda.
