Status: affected by circulating vaccine-derived poliovirus type 2 (cVDPV2)
Polio this week in Mauritania
- No circulating vaccine-derived poliovirus type 2 (cVDPV2) positive environmental sample was reported this week. There were seven positive samples linked to the Jigawa outbreak in 2021.
International Health Regulations
Mauritania is classified by the International Health Regulations (IHR) as a state infected with cVDPV2, with or without evidence of local transmission. It is therefore subject to Temporary Recommendations issued by the International Health Regulations Emergency Committee on Polio Eradication (issued as of 1 November 2022).
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.
