Israel: cases of polio vaccine virus (cVDPV3)

01 aprile 2022

At the beginning of March, an almost 4-year-old girl from Jerusalem was diagnosed with acute flaccid paralysis. Circulating vaccine poliovirus type 3 (cVDPV3) was detected in the stool. In the course, another 5 persons were diagnosed with cVDPV3 and one suspected case is still awaiting test results. All 7 persons had not been vaccinated against polio.

Further testing revealed genetic links to VDPV3 strains detected in environmental samples collected from sites in Jerusalem and Bethlehem between September 2021 and January 2022. Health authorities are currently conducting epidemiological and virological investigations on site to further determine the source and origin of the isolated virus and the associated potential risk of further spread.
