Polio virus sample found at Brazil airport

A WHO statement released on Monday said the virus was found in samples taken from sewage at Viracopos International Airport in Sao Paulo state in March.

It said the local population's high immunity to the disease "appears to have prevented transmission".

Brazil has been polio-free since 1989 and has high vaccination coverage...

WHO Statement

Detection of poliovirus in sewage, Brazil

Disease outbreak news

23 June 2014

On 18 June 2014, the National IHR Focal Point for Brazil reported the isolation of wild poliovirus type 1 (WPV1) from sewage samples collected in March 2014 at Viracopos International Airport, in Campinas municipality in the State of S?o Paulo, Brazil.

Virus has been detected in the sewage only; sewage samples collected from the same site subsequent to the detection of WPV1 have been either negative or only positive for Sabin strains or non-polio enteroviruses; to date no case of paralytic polio has been reported.

The isolate was detected through routine environmental surveillance testing of sewage water; there is no evidence of transmission of WPV1.
