Question to the Department of Health and Social Care:

To ask the Secretary of State for Health and Social Care, what proportion figure for asymptomatic transmission the Government is using in its modelling of covid-19 contagion.

On 20 March, the Government published scientific evidence supporting the United Kingdom Government’s response on COVID-19, including modelling on the dynamics of transmission of the virus. Each day, the models are refined and improved as more data becomes available.

Information about the scientific evidence used to support the UK Government’s response can be found at the following link:
