Scientific and medical officers will also be on hand to answer queries.
One question will be chosen each day to be asked at the daily briefing, usually attended by senior political journalists.
Downing Street said: “The government will answer one question from a member of the public at the daily coronavirus (COVID-19) press conference.”

People had to be over 18 years old.
Only one question would be chosen each day and if selected, the person will be contacted by 3 p.m. (1400 GMT)
Mr Johnson said: “I want to serve notice now that these decisions will be taken with the maximum possible transparency and I want to share all our working and our thinking, my thinking, with you the British people.”
