Ukraine

Status: affected by circulating vaccine-derived poliovirus type 2 (cVDPV2)

Polio this week in Ukraine

  • No case of circulating vaccine-derived poliovirus type 2 (cVDPV2) was reported this week. There were two cases reported in 2021.
  • Disease surveillance continues to be strengthened, to the degree possible given the evolving situation, including by building capacity, conduct trainings, implement environmental surveillance and support routine immunization.

WHO risk assessment

Because of relatively limited international travel to and from this area, and sanitation infrastructure nationally and in neighbouring countries, the risk of international spread of this virus is currently assessed as low.

WHO advice

It is important that all countries, in particular those with frequent travel and contacts with polio-affected countries and areas, strengthen surveillance for AFP cases in order to rapidly detect any new virus importation and to facilitate a rapid response. Countries, territories and areas should also maintain uniformly high routine immunization coverage at the district level to minimize the consequences of any new virus introduction.

International Health Regulations

Ukraine 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).

Travel advice

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.
