COVID-19 shows an array of symptoms that include cough, fever and difficulty in breathing. As the disease evolved, many patients reported the loss of smell and taste as other accompanying symptoms.
A new study recently revealed that the virus may also trigger the appearance of a rash inside the mouth which was found in a few patients in Spain.
Study Method
To arrive at the findings in this new study, the researchers examined 21 consecutive patients that had presented with both a skin rash and COVID-19 at the Ramon y Cajal University Hospital in Madrid between March 30 and April 8.
The aim of this study was to determine whether the patients developed the enamthem ie lesions on mucous membranes, inside the oral cavity.
The oral cavities of the patients who had the enamthems were systematically examined and categorised into four groups – petechial, macular, macular with petechiae, or erythematovesicular.
Results
Out of the 21 patients examined in the study, six of them showed the presence of oral lesions. All of these patients were in the age group of 49-60 years and four out of six patients were female.
The enanthem was macular in 1 patient, petechial in 2 patients, and macular with petechiae in 3 patients, and was located in the palate in all patients. No patient presented with an erythemato-vesicular enanthem.
The mean time between the onset of COVID-19 symptoms and the appearance of mucocutaneous lesions was 12.3 days (range, −2 to 24 days).
