American dermatologists have identified another possible symptom of the coronavirus, which sometimes manifests itself without other signs of infection: a lesion on the skin of the toes that looks like severe frostbite.

Specialists from the International League of Dermatological Societies and the American Academy of Dermatology (AAD) analyzed 505 cases of confirmed COVID-19, of which 318 were mild. In most patients, signs of infection subsided within a few weeks, in some cases they persisted for up to 150 days.

Dermatologists noticed that in 55% of patients, the only symptom was a specific lesion of the skin of the toes, similar to frostbite. As a rule, in such cases, irritation of a bright red color appears, which later acquires a purple tint. Sometimes this condition is accompanied by painful sensations in the fingers, itching and blisters appear.

The authors of the study note that four patients in the sample developed these symptoms before the coronavirus was confirmed, in another 14 people they developed after receiving a positive PCR test. According to experts, “purple fingers” should be added to the criteria for diagnosing coronavirus.

Note that in recent months, scientists and doctors from all over the world have increasingly indicated that the coronavirus can proceed without typical signs of infection – fever, sore throat, chills, and sometimes “hide” behind non-obvious symptoms. A recent study by the British Bureau of National Statistics reported that of 115 PCR-positive patients, only 27 reported any symptoms. Moreover, 16 people from this group reported about the signs that are considered characteristic of COVID-19. That is, 99 people (86%) did not have typical symptoms.

“There is now a focus on people with symptoms, but if all asymptomatic or pre-symptomatic people are not found, it can be difficult to control outbreaks before they get out of control,” said Irene Petersen of University College. London, co-author of the studyniya.
