The latest possible symptom of COVID-19 can be a painful one

Fever, tiredness, and dry cough are the most common symptoms of COVID-19, but new research suggests that skin rash might be another symptom of the virus.

Researchers from Italy and Thailand released studies from both dermatologists and doctors working with COVID-19 patients. In Italy, dermatologists found that in a group of 88 confirmed cases, 20% of the patients developed symptoms on their skin. The most common rashes were erythematous rash, while others developed hives and one even had chickenpox-like bumps. The area in which the rash was most common was in the trunk, also known as the abdomen region.

Doctors in Thailand found that COVID-19 patients with a rash were initially misdiagnosed with dengue fever, which a rash is known as a common symptom, according to the Mayo Clinic.

These cases have forced additional research efforts in the US. The American Academy of Dermatology started a COVID-19 registry for physicians and health care professionals to document medical care workers who are taking care of COVID-19 patients. The survey seeks health care professionals who have taken care of COVID-19 patients “who develop dermatologic manifestations” or dermatology patients with an existing condition who then developed COVID-19.

Some cases in the US have involved patients getting lesions on their feet, which has been dubbed as “COVID toes.” Dr. Esther Freeman, a dermatologist at Massaschuttes General Hospital in Boston, told TODAY that COVID toes can appear as purple lesions on feet or hands. It usually starts with red or purple discoloration, with the skin possibly becoming raised or develop ulcerations, according to the report.

COVID toes can also cause the skin to feel hot, burning or itchy, according to TODAY.

Mild to moderate cases of COVID-19 often include fever and respiratory complications like the difficulty of breathing. The American Academy of Ophthalmology warned that pink eye could be another symptom of the coronavirus, which developed in 1-3% of patients who tested positive for the virus.
