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 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.
  • Following confirmation of two cases of circulating vaccine derived poliovirus type 2 (cVDPV2) in a refugee camp area of Unity state, South Sudan, two weeks ago, preparations for outbreak response immunization activities are being finalized in the country. National Immunization Days (NIDs) were implemented on 4–7 November, with further campaigns planned for December and January. The objective is to rapidly stop the cVDPV2 in the infected area, while further boosting immunity to type 1 polio and to minimize the risk of renewed outbreaks following virus re-introduction from infected countries and areas.
  • In November, supplementary immunization activities (SIAs) are being held in Djibouti, Ethiopia, Kenya, Somalia, and Sudan, and Child Health Days (CHDs) including polio vaccines in Yemen.
