MADRID, Spain – Changes in the tongue, hands or soles of the feet could give an early indication of Covid-19 infection, Spanish researchers found in a study presented on Tuesday.
The findings emerged from research conducted among 666 patients with Covid-1
One in four patients said they had noticed changes in their tongue, while four in 10 saw unusual signs on the palms or soles of their feet.
The study was conducted in April by health professionals from Madrid’s La Paz hospital and primary care services with the results published in the British Journal of Dermatology in the form of a “research letter” in September.
Some patients reported swelling of the tongue and the appearance of spots in what has been called the ‘Covid tongue’, which on many occasions was associated with a loss of taste.
Another symptom was a burning sensation and redness on the palms or soles of the feet, which in some cases was followed by the appearance of small spots.
“Nearly half of patients with mild to moderate Covid-19 who were admitted to a field hospital for a two-week period showed mucocutaneous findings,” the letter said.
“The oral cavity was often involved and deserves specific examination under appropriate circumstances to avoid the risk of infection.”
