A chickenpox-type rash known as an erythemato-vesicular rash is another skin symptom to be aware of.
The rash involves areas of small, itchy red bumps that can occur anywhere on the body, but particularly the elbows and knees as well as the back of the hands and feet.
The rash can persist for days or weeks.
Covid fingers and toes known as chilblains are reddish and purplish bumps on the fingers or toes, which may be sore but not usually itchy.
This type of rash is most specific to COVID-19, is more common in younger people with the disease, and tends to present later on.
