Kenya

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 new wild poliovirus type 1 (WPV1) cases have been reported in the past week in countries of the Horn of Africa. The most recent case, which had onset of paralysis on 11 August, was from Hobyo district of Mudug province, central Somalia. The total number of cases that have been reported in the Horn of Africa in 2014 is six: 1 WPV1 in Ethiopia (date of onset of paralysis on 5 January) and 5 WPV1s in Somalia.
  • No cases of type 2 circulating vaccine derived poliovirus (cVDPV2) were reported in the past week. The most recent case of cVDPV2 had onset of paralysis in South Sudan on 12 September.
  • Following confirmation at the beginning of November of two cases of cVDPV2 in a refugee camp area of Unity state, South Sudan, outbreak response plans are in place to hold rounds of supplementary immunization activities (SIAs). Subnational Immunization Days are taking place on 16 – 19 December and 20 – 23 January. The objective is to rapidly stop the transmission of cVDPV2 in the infected area, while further boosting immunity to type 1 wild poliovirus and to minimize the risk of renewed outbreaks following wild poliovirus re-introduction from any infected countries and areas.
  • National Immunization Days (NIDs) are taking place in Djibouti, Ethiopia and Somalia and Subnational Immunization Days (SNIDs) in Kenya and Sudan in December. SNIDs are scheduled in January in South Sudan, and NIDs in Somalia and Uganda.
