The Zoe app has found a new symptom for the Omicron variant, a skin rash has now been labelled as "key" if you think you might have the variant.
People have been reporting two different kinds of skin rashes:
The first, and more likely to appear, is a hive-like rash, which has raised bumps and can be very itchy. It is thought this starts on your palms or the soles of your feet.
The second rash is a prickly heat-type rash, which appears all over your body, but more commonly on your elbows, knees and the back of your hands and feet.
The ZOE Symptom Covid Study said the top five symptoms of the variant are a runny nose, headache, fatigue (mild or severe), sneezing and a sore throat.
Symptoms of the initial form of the Covid-19 virus are also present such as a cough, fever and a loss of smell or taste.
