Poliovirus Detected in Israel
In Israel, wild poliovirus type 1 (WPV1) was isolated from sewage samples collected on 9 April 2013 in Rahat, southern Israel. The virus has been detected in sewage only; no case of paralytic polio has been reported. Genetic sequencing and epidemiological investigations are ongoing to determine its origin. Preliminary analyses indicate the strain is not related to the virus currently affecting the Horn of Africa.
The virus isolate was detected through routine environmental surveillance in Israel that involves regular testing of sewage water. Israel has been free of indigenous WPV transmission since 1988. In the past, wild poliovirus has been detected in environmental samples collected in this region between 1991 and 2002 without occurrence of cases of paralytic polio in the area.
