Poliovirus Variant Detected In London Sewage Samples According To WHO

In 2020, the WHO reported nearly one thousand confirmed cases of VDPV2 worldwide. Now, the resurfacing of this variant has experts alarmed.

“There may be a localized spread of poliovirus, most likely within individuals that are not up to date with polio immunizations,” Kathlene O’Reilly, a polio eradication expert, said on Wednesday about the London discovery.

“The most effective way to prevent further spread is to check vaccination histories, especially of young children, and ensure that polio vaccination was included,” she added.

Moving forward, the UK Health Security Agency also plans to assess the origin and risk of circulation of the variant, increase poliovirus surveillance, explore routine immunization catch-up, and keep the public updated.
