A follow-up: there is conflicting evidence over the extent to which the disease is transmitted in supermarkets. Public Health England report that supermarkets are the most frequent common exposure setting for Covid-19 in England, with 18% of transmissions occurring after visits there. On the other hand, and make of that what you will, Isabel Oliver, director of the National Infection Service at PHE, has said: “Suggestions that supermarkets are causing COVID-19 to spread are inaccurate. Common exposure data does not prove where people are contracting COVID-19. It simply shows where people who have tested positive have been in the days leading up to their test and it is used to help identify possible outbreaks.”https://www.independent.co.uk/news/uk/home-news/covid-supermarkets-uk-exposure-nhs-b1748906.html
