Study: Most People Infected With Coronavirus During U.K. Lockdown Had No Symptoms When Tested

A team of researchers in the U.K. are calling for more widespread coronavirus testing after finding that more than four in five Britons who tested positive during the country’s lockdown did not exhibit the symptoms most commonly associated with a Covid-19 infection, like a fever, lasting cough or a loss of taste or smell. “The fact that so many people who tested positive were asymptomatic on the day of a positive test result calls for a change to future testing strategies,” said Irene Petersen, a professor at UCL in a statement. “More widespread testing will help to capture ‘silent’ transmission and potentially prevent future outbreaks.”
