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 on Wednesday.
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.
In a statement released Tuesday, the WHO said it believed "the risk of international spread from Ukraine to be low" but noted the infected region shared borders with Romania, Hungary, Slovakia and Poland.
The WHO Regional Office for Europe said it had been notified of the cases late last month, adding it would help Ukrainian authorities tackle the virus.
"WHO and UNICEF are providing the ministry of health with both technical and on-site support in planning and implementing large-scale supplementary immunisation activities with oral polio vaccine (OPV) to rapidly stop (the) circulation of the virus," the WHO said.
The Ukrainian health ministry conceded that the country had struggled getting children vaccinated against the crippling virus since 2008.
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.
Affecting mostly children under the age of five, polio can lead to irreversible paralysis.
According to the WHO, the number of polio cases has decreased by over 99 percent since 1988. Only 416 cases were recorded in 2013, down from the 350,000 people infected with the virus in 1988.
Three countries -- Afghanistan, Nigeria and Pakistan -- were considered polio-endemic by the WHO last year.
