Status: Affected by circulating vaccine-derived poliovirus type 2 (cVDPV2)
Polio this week in Cameroon
- No case of circulating vaccine-derived poliovirus type 2 (cVDPV2) was reported this week. There were three cases reported in 2021.
International Health Regulations
Cameroon is classified by the International Health Regulations (IHR) as a state infected with cVDPV2, with potential risk of international spread. It is therefore subject to temporary recommendations as of February 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.
