According to polio eradication experts, there may be localized spread of polio virus in London that would most likely be present in the individuals not up to date with polio immunizations.

Vanessa Saliba, consultant epidemiologist at UK Health Security Agency, has said that the risk gets low when majority of population is fully vaccinated. She also added that the areas with polio virus transmission have the lowest infection rates and because of this, the spreading virus in these communities has put the not-fully vaccinated at greater risks.
