Risk assessment: Wild-type poliovirus 1 transmission in Israel – what is the risk to Europe?
The EU/EEA countries and the rest of the WHO European Region, have been officially polio-free since 2002. However, wild-type polio virus 1 (WPV1) has been isolated in sewage and in the faeces of asymptomatic carriers in Israel since February 2013. In this risk assessment ECDC looks at the potential impact of this public health event on the risk of poliovirus being imported and re-established into circulation in EU/EEA.
Expert consultation on scientific evidence linked to polio virus in Israel and Syria
In response to the recent events of wild-type poliovirus (WPV) circulation in Israel and a cluster of poliomyelitis cases in Syria, ECDC published two risk assessments for the EU/EEA on 26 September and 24 October 2013, respectively.
Risk of introduction and transmission of wild-type poliovirus in EU/EEA countries following events in Israel and Syria – updated risk assessment (9 December 2013)
The confirmed circulation of wild-type poliovirus (WPV) in Israel and the outbreak of poliomyelitis in Syria mean that there is a high risk the disease will be reintroduced into the EU/EEA.
Epidemiological update: Polio virus in sewage and human faecal samples in Israel, August 2013
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.
Epidemiological update: Polio in Israel, 14 October 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.
