Liberia

Status: imported poliovirus

Liberia 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 poliovirus originating from northern Nigeria. The immediate priority is to stop all active outbreaks using mop-up campaigns with monovalent 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

  

Polio this week in West Africa

  • No WPV1 cases have been reported in West Africa in 2014. The most recent WPV1 case in the region occurred in Tahoua province, Niger, with onset of paralysis on 15 November 2012. In addition, a single case of cVDPV2 was reported in Niger on 11 July 2013.
  • Polio staff across West Africa are supporting efforts to control the Ebola outbreak affecting the region. The Ebola outbreak will impact the planned multi-country polio campaigns in September in the Ebola affected countries with campaigns in Liberia, Sierra Leone, and Guinea being postponed until the Ebola outbreak is brought under control. Preparations for large scale multi-country campaigns in countries across the rest of West Africa in mid-September are proceeding as planned.
