ECDC has published Rapid risk assessment on polio outbreak in Ukraine. Click or tap through for the RRA and many links.
Two cases of paralytic poliomyelitis caused by circulating vaccine-derived poliovirus type 1 (cVDPV1) were confirmed in Ukraine on 28 August 2015. The genetic similarity between the isolates indicates active transmission of cVDPV1. Both cases are from the Zakarpatskaya oblast [region], in south-western Ukraine, bordering Romania, Hungary, Slovakia and Poland.
There is a risk that cVDPV will be imported and transmitted in the EU via a recently infected person shedding the virus and this is assessed in a new ECDC rapid risk assessment. The highest risk of importation and onward transmission is likely to exist in the border areas with Ukraine, particularly in areas where under-vaccinated populations are concentrated on both sides of the border and where there is a high volume of border crossings in both directions.
However, the risk that importation of cVDPV from Ukraine to the EU/EEA would result in a case of paralytic poliomyelitis is low, given the high polio vaccination uptake in EU/EEA Member States.
Member States are also encouraged to review the options proposed by ECDC in the 2013 rapid risk assessment Wild polio virus 1 transmission in Israel – what is the risk to the EU/EEA? Public health authorities, travel medicine clinics and other healthcare providers should advise EU residents who plan to visit Ukraine of the need to be up-to-date with their polio vaccinations.
