A pioneering study worldwide, carried out by professionals from the La Paz University Hospital in Madrid, has revealed for the first time that alterations in the language constitute a new symptom of Covid-19.
The so-called ‘Covid tongue’ consists of an increase in the size of the tongue and other lingual lesions, such as depapilation in patches or smoother areas of the tongue, which are often associated with loss of taste.
This symptom can be a sign of Covid-19, together with those already known as fever or cough, and can facilitate the early detection of the infection.
Another symptom that can warn of Covid-19 infection is changes in the palms of the hands and the soles of the feet, specifically, a burning sensation followed, on some occasions, by peeling or the appearance of small very obvious stains.
The research, led by the Dermatology Service of the La Paz University Hospital and with the participation of eight Primary Care physicians, was carried out during the month of April, and concludes that 25 percent of the Covid-19 patients presented alterations in the tongue and mouth, and up to 40 percent in the palms and soles.
The research, published in the British Journal of Dermatology, a world reference in dermatological processes, represents an advance in the early detection of coronavirus, since it adds data with scientific evidence to the symptoms already described.
The coronavirus has been linked to multiple respiratory, thrombotic, neurological, digestive or skin symptoms.
However, until the publication of this scientific finding, oral alterations and palmoplantar lesions associated with Covid-19 had not been considered.
