Researchers in Spain have now listed a new COVID-19 symptom which is rashes on the inside of the mouth that are clinically known as enanthem. The new study was published in JAMA Dermatology on July 15 led by Dr. Juan Jimenez-Cauhe, of University Hospital Ramony Cajal in Madrid. As many as 21 patients in the month of April were diagnosed and had skin rashes. Amongst those six patients (29%) had enanthem on the inside of their mouths. The study further read that the rash could appear anywhere from two days before the onset of other COVID symptoms to 24 days after, with 12 days as an average time.
Dr. Michele Green, a dermatologist who practices at Lenox Hill Hospital in New York City said, "An enanthem is a rash typically small spots that are either reddish or white on the mucous membranes. It is very common in patients with viral infections like chickenpox and hand, foot, and mouth disease. It is characteristic of many viral rashes to affect mucous membranes."
Further, the enanthem didn't have all the earmarks of being attached to any meds the patients were taking, further fortifying the thought that it was sickness with the new coronavirus making the red spots show up. WHO had earlier, said the most common symptoms of COVID-19 are fever, tiredness, and dry cough. Some patients may have aches and pains, nasal congestion, runny nose, sore throat or diarrhea. These symptoms are usually mild and begin gradually. Some people become infected but don’t develop any symptoms and don't feel unwell.
