The U.K. Health Security Agency (UKHSA) recently announced it continues investigating the source of the poliovirus identified in wastewater systems across London, England.
The UKHSA stated on October 19, 2022, it is most likely that an individual entered the U.K. in February 2022 from a country where the oral polio vaccine (OPV) had been used for immunization campaigns.
Recently vaccinated individuals can shed the OPV virus in their stool for a few weeks following vaccination enabling the virus to be detected through sewage surveillance.
