Guinea

Status: has stopped indigenous wild poliovirus (WPV) circulation but affected by outbreak of imported WPV or circulating vaccine-derived 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.

Polio this week in Guinea and West Africa

  • No circulating vaccine-derived poliovirus type two (cVDPV2) cases have been reported from Guinea in 2016. The most recent case was reported from Kankan district with onset of paralysis on 14 December 2015. The total number of cVDPV2 cases for 2015 is seven.
  • While signs are positive in Guinea, and it has been more than a year since the last case had onset of paralysis, gaps remain sub-nationally both in population immunity and surveillance sensitivity. Undetected circulation cannot be ruled out. Efforts are continuing to rapidly fill these gaps and ensure the outbreak has been stopped.
