We found changes in the tongue that until then had not been linked to Covid: the tongue is enlarged, it appears swollen, the teeth marks can be seen and it can also be depapillated, with small indentations in the back where the taste buds are flattened. It looks like a tongue with red markings,” explains Nuño González, whose team announced the findings of the research in a press release on Tuesday.
The dermatologist and her colleagues studied 666 Covid patients who were admitted to the Ifema field hospital between April 10 and 25 in 2020. The average age of the patient was around 56 and nearly half were of Latin American origin. All had minor or moderate cases of pneumonia. The study from the doctors found that more than 25% of the patients also presented changes in the oral mucosa (the mucous membrane lining the inside of the mouth) such as transient lingual papillitis (11%), which is a kind of blemish on the tongue, mouth ulcers (7%), tongue inflammation with teeth indentations (7%), burning sensation (5%) and tongue inflammation with patchy depapillation or loss of lingual papillae (4%), according to the results, which were published last September in the British Journal of Dermatology.
