The Ministry of Health of Ukraine has reported a case of polio in a young child in the Rivne area of western Ukraine. The child was unvaccinated against polio.
The World Health Organization (WHO) are working closely with the health authorities in Ukraine to determine if there has been any local transmission and to assess the risk of local circulation.
Polio is extremely rare in Europe, although a small number of cases have occurred in Ukraine since 2010.
Poliomyelitis is spread mainly through person to person contact via the faecal-oral route.
