Polio eradication this week:
- In Ukraine, a circulating vaccine-derived poliovirus type 1 (cVDPV1) outbreak has been confirmed. Two cases have been confirmed, with dates of onset of paralysis of 30 June and 7 July. The genetic similarity between the cases indicates active transmission of cVDPV1. Both are from the Zakarpatskaya oblast, in south-western Ukraine, bordering Romania, Hungary, Slovakia and Poland. Ukraine had been at particular risk of emergence of a cVDPV, due to inadequate vaccination coverage. In 2014, only 50% of children were fully immunized against polio and other vaccine-preventable diseases. Discussions are currently ongoing with national health authorities to plan and implement an urgent outbreak response. More.
