Molecular epidemiology of silent introduction and sustained transmission of wild poliovirus type 1, Israel, 2013.

Poliovirus vaccine coverage in Israel is over 90%. The last nine birth cohorts have been vaccinated exclusively with inactivated polio vaccine (IPV). However, between February and July 2013 type 1 wild poliovirus (WPV1) was detected persistently in 10 and intermittently in 8 of 47 environmental surveillance sites in southern and central Israel and in 30 stool samples collected during July from ...

Field study of fecal excretion as a decision support tool in response to silent reintroduction of wild-type poliovirus 1 into Israel.

BACKGROUND Israel has used an inactivated polio vaccine (IPV)-only schedule since 2005 (95% coverage). Silent reintroduction of wild type poliovirus 1 (WPV1) into Israel in early 2013 was detected in Southern Israel via routine environmental surveillance without clinical cases. OBJECTIVES To estimate the rate of WPV1 excretion by age and residence and inform decision-making regarding suppleme...
