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.
