Kiev: Two polio cases have been confirmed in western Ukraine, the first to be recorded in Europe since 2010, the World Health Organization (WHO) said today.
A 10-month-old baby and a four-year-old child were diagnosed with the polio virus in Ukraine's southwestern Zakarpattya region, which borders four European Union member states, after paralysis associated with the disease was detected, the Ukrainian health ministry had said on Tuesday.
"It's the first polio case in Europe since 2010," WHO spokesman Oliver Rosenbauer told AFP.
The last case of polio had previously been recorded in Ukraine in 1996, he added.
The two cases are tied to a different type of virus than the one responsible for the 2010 outbreak, said the WHO.
"The Ukrainian outbreak counting two cases in two children from the Zakarpattya region to date is due to circulating vaccine-derived poliovirus (cVDPV) type 1," said WHO spokeswoman Cristiana Salvi.
"This means that because of low vaccination coverage, this strain was allowed to circulate in a community as it continued to find susceptible individuals," she said.
Ukrainian deputy health minister Igor Pereginets separately told AFP on Wednesday that a similar polio virus which causes poliomyelitis was detected last year.
Inadequate vaccination puts Ukrainian children at risk of contracting the virus, with only half fully immunised against polio and other vaccine-preventable ailments last year, the Global Polio Eradication Initiative said.
The Ukrainian health ministry conceded that the ex-Soviet country had struggled to get children vaccinated against the crippling virus since 2008.
