Early Reports of Skin Symptoms
Early reports from Italian dermatologists working with COVID-19 patients found that 20% of patients developed skin symptoms in a group of 88 confirmed coronavirus cases.
Almost half of the patients developed a rash on the onset of the disease and little more than hale developed after hospitalization.
The most common manifestations noticed were erythematous rash or patchy red skin. While few developed urticaria, or hives and one developed chickenpox-like blisters.
An early report from Thailand suggested a patient was misdiagnosed with dengue fever, the patient was presented with petechiae or broken blood vessels which is common in dengue.
Other reports suggest COVID-19 patients developing lovedo reticularis, or mottling, which could indicate occlusion of blood vessels near the skin.
