Video: Scientists Describe Changes In The Oral Mucosa With COVID-19
Scientists describe changes in the oral mucosa with COVID-19
A rash on the mucous membrane is characteristic of viral infections.
Spanish scientists have described a rash on the oral mucosa (enanthema) in patients with COVID-19. Their work is published in JAMA Dermatology.
Dermatologists at Hospital Universitario Ramon y Cajal note that the skin symptoms that are found in COVID-19 have been described many times. But the oral cavity of patients with coronavirus infection or with suspicion of it is often not examined by doctors for safety reasons.
The authors followed 21 patients with skin rashes associated with COVID-19. Each of these patients underwent a thorough examination of the oral mucosa. Enanthema, a rash on the mucous membrane, was found in six.
Enanthema in all patients was located on the palate, it was represented by spots and small hemorrhages (macular-petechial). She appeared on average 12 days, there was no indication that it was caused by another cause (not a virus).
The authors believe that their work, despite its small size, is of interest: their data will help prove the viral origin of some types of skin rashes.
The fact is that earlier doctors described a rash with COVID-19, but it was difficult for them to prove that it was the coronavirus that caused it. The found enanthemes have a form and location characteristic of viral infections. Therefore, the accompanying rash is probably caused by the same pathogen. Scientists noticed that some types of skin rash did not occur with enanthema - urticarial (blisters) and maculopapular (spots with nodules).
