Status: no longer poliovirus-infected, but at high risk of outbreaks

Somalia 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 priority is to maintain high levels of immunity and strong disease surveillance, to minimise the risk and consequences associated with a potential re-infection or re-emergence of poliovirus.

WHO’s International Travel and Health recommends that all travellers to polio-affected areas be fully vaccinated against polio. Residents (and visitors for more than 4 weeks) from infected areas should receive an additional dose of OPV or inactivated polio vaccine (IPV) within 4 weeks to 12 months of travel.

Key at-risk: no longer poliovirus-infected, but at high risk of outbreaks
Outbreak: has stopped indigenous WPV circulation but affected by outbreak of imported WPV or circulating vaccine-derived poliovirus
Endemic: has never stopped indigenous wild poliovirus (WPV) circulation


IHR Classification

Somalia is classified by the International Health Regulations (IHR) as a state no longer infected by wild poliovirus or circulating vaccine-derived poliovirus , but which remain vulnerable to international spread, and states that are vulnerable to the emergence and circulation of vaccine-derived poliovirus. Hence it is subject to temporary recommendations as of August 2016.
