​In May 2013, Israel announced the detection of wild poliovirus type 1 (WPV1) in the south of the country (1). As reported until mid-August, during the routine monitoring of sewage samples the virus had been found in 67 sewage samples from 24 sampling sites since February 2013.

​As of 3 October, wild-type poliovirus 1 (WPV1) was still being isolated in wastewater treatment plants across the country with some areas indicating an inconsistent or discontinued detection. However, no new sites in Israel with WPV1 in sewage were detected since the start of the bivalent oral polio vaccine (bOPV) immunisation campaign, according to personal communication from the Ministry of Health in Israel.

​Ten of the 22 acute flaccid paralysis (AFP) cases in the Syrian Arab Republic suspected of being caused by wild poliovirus have been confirmed as wild poliovirus type 1 (WPV1) by the World Health Organization (WHO).
