London sewage samples contain poliovirus, officials say
Fox News
Poliovirus has been detected in London sewage, according to the U.K. Health Security Agency (UKHSA). The samples were collected in northern and eastern London.
It said that it is normal for one to three "vaccine-like" polioviruses to be detected in U.K. sewage samples each year, but that those have always been "one-off findings."
The previous detections occurred when an individual vaccinated overseas with the live oral polio vaccine (OPV) returned or traveled to the U.K. and briefly "shed" traces of the vaccine-like polioviruses in their feces.
