Data from the Zoe Covid Symptom study suggests that many users of the app are reporting these milder symptoms, rather than the classic Covid symptoms that include a cough, fever, and loss of smell or taste.
This is believed to be linked to the Delta variant, which now accounts for 90% of Covid cases in the UK and was first identified in India.
Professor Tim Spector, who is leading the study, said that while for younger people the Delta variant can feel “like a bad cold,” that doesn’t mean they’re less contagious, the BBC reported.
He said: “As of early May, we’ve been looking at the main symptoms among app users – and they’re not the same as they used to be. “
He added that a fever was still a fairly common symptom of Covid-19 reported on the app, but loss of smell was becoming less and less common.
“This variant seems to work slightly differently,” he explained.
“People might think they just had some sort of seasonal cold and still go to parties and can pass it on to six other people.
“We think that is really fueling the problem.
“The message here is that if you’re young you’re going to have milder symptoms anyway.
“It might sound like a bad cold or a funny ‘deactivated’ feeling, but stay home and take a test. “
These included chills, loss of appetite, headaches, and muscle pain.
According to the NHS, the symptoms of Covid to watch out for are: “a new continuous cough, high temperature, loss or change in smell or taste”.
They add: “Most people with symptoms have at least 1” and go on to mention that one in three people with Covid-19 does not have any symptoms.
Anyone who thinks they might have Covid-19 is urged to get tested.
