Urticarial rashes can present quite early in the infection but can also last a long time later when the affected person is no longer contagious. The rash appears as sudden raised hives or wheals on the skin which come and go quite quickly over hours and are usually intensely itchy. It can involve any part of the body. If it affects the face, it can cause swelling of the lips and eyelids. The eruption can also start with intense itching of the palms or soles. It is usually treated with antihistamines. If the patient has lip swelling it is important to check that there is no difficulty in breathing or wheezing as this would need urgent medical attention.
