Health authorities said although the risk to the general public is low but added that poliovirus can spread.
The officials urged children to get vaccinated with the NHS asked to report any suspected case to the UKHSA. It is seen as a threat to children and young adults.
Poliovirus causes illness and paralysis to those who have not been vaccinated as the WHO informed that polio immunisation in London stood at 87 per cent.
The UK Health Security Agency (UKHSA) said “multiple sewage samples were collected from the London Beckton Sewage Treatment Works between February and June 2022.” The area reportedly covers north and east London.
The UKHSA said it is investigating the extent of transmission of the virus in northeast London.
