MADRID – 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 Tuesday.
The conclusions emerged from an investigation carried out among 666 patients with Covid-19 at the IFEMA field hospital in Madrid established during the first wave of the pandemic, the regional government said.
One in four patients reported having noticed changes in the tongue, while four in 10 detected unusual signs on the palms of the hands or the soles of the feet.
‘Research letter’
The study was carried out in April by health professionals from the Madrid hospital of La Paz and from the primary care services, and the results were published in the British Journal of Dermatology in the form of a “research letter” in September.
Some patients reported a swelling of the tongue and the appearance of patches, in what has been called ‘Covid tongue’, which on many occasions was associated with a loss of taste.
Feeling of burning
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 blemishes.
“Almost half of the mild to moderate Covid-19 patients admitted to a field hospital over a two-week period showed mucocutaneous findings,” the letter read.
“The oral cavity was frequently affected and deserves a specific examination in the right circumstances to avoid the risk of contagion.”
