Thank you for your request.

The Office for National Statistics COVID-19 Infection Survey is a household survey that estimates the number of people testing positive for infection and for antibodies in the UK. Our statistics refer to the number of current COVID-19 infections within the population living in private residential households. We exclude those in hospitals, care homes and/or other communal establishments. In communal establishments, rates of COVID-19 infection are likely to be different.
