Sarah Crofts, senior statistician for the ONS Covid-19 Infection Survey said: ‘Our analysis today highlights the range of symptoms people can experience with Covid-19.’
She said: ‘The classic symptoms of fatigue, headache and cough are still the most commonly reported by those infected with the virus, while only around 1 in 5 experience loss of taste or smell only.
‘Around half of those we tested did not report any symptoms even whilst having high levels of the virus present in their body. This underlines that people in the community may unknowingly have the virus and potentially transmit it to others.
‘It is vital we continue to measure infection levels in the population and collect information on symptoms so we can identify any changes that may otherwise go undetected.’
The strength of the test was measured by a cycle threshold (Ct) value and the lower the Ct value, the higher the viral load and stronger the positive test, the ONS said.
Symptoms from people who tested positive for Covid with a strong positive test were reported between December 1 last year and March 22.
All figures are for people in private households and excludes cases in hospitals, care homes and other institutional settings.
