Only 22 percent of people testing positive for coronavirus reported having symptoms on the day of their test, according to the Office for National Statistics.
This hammers home the importance of “asymptomatic transmission” - spread of the virus by people who aren’t aware they’re carrying it.Health and social care staff appeared to be more likely to test positive, reports BBC. This comes as deaths from all causes in the UK fell to below the average for the second week in a row. Between the end of March and June, there were 59,000 more deaths than the five-year average.
While the ONS survey includes relatively small numbers of positive swab tests (120 infections in all) making it hard to make any strong conclusions about who is most likely to be infected, there are some patterns coming through in the data: Those in people-facing health or social care roles, and working outside their homes in general, were more likely to have a positive test. People from ethnic minority backgrounds were more likely to have a positive antibody test, suggesting a past infection. White people were the least likely proportionally to test positive for antibodies.
