Fewer than one in five people request a Covid-19 test if they have symptoms, while adherence to self-isolation is low, according to a large study examining the Test and Trace system.Experts, including from the Public Health England behavioural science team at Porton Down in Wiltshire, found that only half of people could identify the main coronavirus symptoms, which include a cough, high temperature and loss of taste or smell.
