TORONTO --
The list of possible COVID-19 symptoms continues to grow.
"COVID tongue," or symptoms characterized by irritations and lesions in the mouth and tongue, have been causing concern for researchers, as well as "COVID toes," which are characterized by rashes and inflammation in the toes and feet.
Last September, a study conducted in Spain involving 666 COVID-19 patients found that 78 participants developed lesions on their tongues. Most patients reported a reduction in taste sensation, but 5.3 per cent reported a burning sensation.
The study also found that 121 patients developed irritations on their palms and soles of their feet.
Dr. Douglas Fraser is a professor at Western Universityâs Schulich School of Medicine & Dentistry and a pediatric critical care physician at London Health Sciences Centre in London, Ont. He said that the tongue has a high concentration of ACE receptors, which are the receptors that the SARS-CoV-2 virus binds to.
