No symptoms for 86pc of Covid cases, says UK study
People who were asymptomatic accounted for 86pc of the people who tested positive for Covid-19 in a UK sample population during lockdown, a study showed on Thursday, meaning the current policy of testing people with symptoms might miss many cases.
In England, people are encouraged to get tested for Covid-19 only if they have symptoms of a persistent cough, fever, or loss of taste or smell, with suspected contacts of positive cases told to self-isolate in the first instance.
