Via BBC News: One in 400 people in England has coronavirus, tests suggest. Excerpt:
One in 400 people in England is infected with coronavirus, a survey of 11,000 people in households suggests.
They were asked to carry out swab tests over the two weeks up to 10 May.
This indicates about 148,000 people in England could be currently infected - 0.27% of the population.
And this could help ministers calculate the reproduction (R) number, or transmission rate, of the virus and whether tracking the contacts of infected people is feasible.
The study is set to expand over time to test 25,000 people in private households across all four UK nations.
The 5,000 households tested in this survey did not include hospital patients or people living in care homes, where rates of Covid-19 are likely to be much higher, Office for National Statistics figures show.
Just 33 of the 11,000 people - in 30 households - tested positive in this snapshot survey.
Health or care workers in those households were several times more likely to be infected than workers in other sectors.
