Poliovirus detected in London sewage samples, UK health officials are on alert

London, June 22: British health officials filed a national appeal on Wednesday to parents to ensure that their children’s vaccines were up-to-date after poliovirus was detected in London’s sewage samples. The UK Health and Safety Agency (UKHSA) said investigations are underway after several closely related viruses were found in sewage samples taken between February and May.

The virus is evolving and is now classified as “vaccine-derived” poliovirus type 2 (VDPV2). This can, in rare cases, cause serious illnesses such as paralysis in people who are not completely vaccinated. This finding is of concern as the last case of wild polio contracted in the United Kingdom was confirmed in 1984 and the United Kingdom was declared polio-free in 2003.

“Vaccine-derived poliovirus is rare and the risk to the general public is very low,” said Dr. Vanessa Saliva, a UKHSA consultant epidemiologist. “Vaccine-derived poliovirus can spread, especially in communities where vaccine intake is low. In rare cases, it can cause paralysis in people who are not completely vaccinated, so you and yours. If your child doesn’t have the latest polio vaccination information, it’s important to contact the GP, “she said. Polio quasi-national immunization day will take place in 11 states, UT, starting today.

According to UKHSA, the detection of VDPV2 may have spread somewhat between closely related individuals in northern and eastern London, indicating that they are currently excreting type 2 poliovirus strains from their faeces. Suggests.

The virus has only been detected in sewage samples and no cases of associated paralysis have been reported, but the study aims to determine if an infection has occurred in the community. UKHSA stated that as part of regular surveillance, it is normal to detect 1-3 “vaccine-like” polioviruses in UK sewage samples each year, but these are always once. It was a limited discovery and was never detected.

These previous detections occur when an individual vaccinated with a live oral polio vaccine (OPV) abroad returns or travels to the United Kingdom and simply “flushes” traces of a poliovirus, such as the vaccine, in the feces. Did.

“The majority of Londoners are completely protected from polio and need no further action, but the NHS has not obtained the latest information on polio vaccination for parents of children under the age of five in London. Jane Craig, chief nurse of the NHS in London, said.

The United Kingdom is considered by the World Health Organization to be free of polio and has a low risk of polio infection due to the high vaccination coverage of the entire population. However, vaccination rates for pediatric vaccines have declined nationwide over the past few years, especially in parts of London, so UKHSA is urging people to make sure their vaccines are up to date.

Wastewater surveillance has been expanded to assess the extent of transmission and identify areas for targeted behavior. According to UKHSA, medical professionals have been warned of these findings so that they can quickly investigate and report those who have symptoms of possible polio, such as paralysis.

The primary polio vaccine course is given to babies in 2, 3 and 4 months. Three doses are required to complete the primary course. In the UK, it is given as part of a 6-in-one vaccine.
