Question to the Department of Health and Social Care:

To ask Her Majesty's Government what estimate they have made of the number of patients with COVID-19 who have been asymptomatic; and of those, how many were subsequently treated.

On 20 March, the Government published scientific evidence supporting the United Kingdom Government response on COVID-19, including modelling on the dynamics of transmission of the virus.

The proportion of cases who are asymptomatic is difficult to estimate. Information about the scientific evidence used to support the UK Government response can be found online via GOV.UK.

Those with COVID-19 who are asymptomatic are unlikely to be treated, as they would not have health issues.
