Entanema – a rash on the mucous membrane – was found in 29% of the patients who participated in the study. This symptom occurred in people about two days before the appearance of other signs of the coronavirus.
So far, scientists can’t say how characteristic the rash is among patients. In many ways, this is complicated by safety requirements, which create difficulties when examining the oral cavity. A total of 21 patients aged 40 to 69 years took part in the study.
