In addition to the sudden loss of taste and smell, experts discovered an additional strange sign in asymptomatic SARS-CoV-2 infected people and temporarily referred to this skin condition as “COVID toes”.


It seems that the longer the coronavirus new strain has been, the more strange symptoms appear. Eye pain, ophthalmologists say, may be a rare sign of COVID-1. In addition, anorexia can occur in patients with COVID-19 who do not exhibit known coronavirus symptoms. Hemoptysis and a tingling sensation throughout the body have also been reported.

Recently, a strange phenomenon from people infected with SARS-CoV-2 virus has caught the attention of researchers. This is a skin condition and is referred to as “toes COVID” by dermatologists. The toes of the patient will have visible lesions with purple or red, some cases can occur with the finger, according to dermatologist Esther Freeman (Massachusetts General Hospital, Boston).

However, since “COVID toe” can be an early condition in a patient with COVID-19 without other symptoms, Dr. Freeman thinks this phenomenon is a criterion for localization of the test. Professor – Doctor of the Department of Dermatology Lindy Fox (University of California, San Francisco) also agrees with this opinion.

What is “COVID toes”?


According to Dr. Freeman, this usually begins with red or purple skin on the toes (perhaps even the fingers), a slight swelling or ulcers, usually concentrated on the tip of the finger or the upper surface. or on both sides of the foot. People with COVID toes also experience hot or itchy skin.

A patient named David, 39 years old, shared his experience of having “toes COVID” with TODAY: “The affected toes initially hurt to touch and to walk … The pain the pain only lasted for more than a week and then gradually disappeared ”.

This phenomenon appears to be specific to those who test positive when making a diagnosis of COVID-19 because, according to a report from the European Journal of Pediatric Dermatology, the condition “has never been reported before”.

What causes “COVID toes”?

Research on this phenomenon has only just begun, but experts have some hypotheses about the cause.

Dr. Freeman believes that the COVID toe is from an inflammatory response caused by the virus. This is like a limb disease when exposed to cold temperatures for a long time, leading to inflammation and appearing as skin sores or swelling.

Another theory is due to thrombosis (blood clots) that can occur in patients with COVID-19.

However, Dr. Freeman said that “toes COVID” is likely to be a combination of the two above hypotheses, it is difficult to confirm that it is due to just one cause.

Is “COVID Toes” common?

There is still not enough statistical data to give an exact figure on this situation. However, Dr. Freeman operates an online international reporting site to document the dermatological conditions of patients with COVID-19.

This report, created in partnership with the American Academy of Dermatology, has reports of positive results in people who have tested and are suspected of being COVID-19.

Of the 90/100 reports from the first week, Dr. Freeman said nearly half of the patients reported purple skin lesions in the feet or hands. Even with some cases, the phenomenon of “toes COVID” is still the only symptom these people experience.

Based on current reports, the condition appears to be more common in children and adolescents, but that does not mean that “toes COVID” is absent in adults. This strange symptom appears at a very early stage of the disease, when the test can give negative results.

Before the US, doctors in Italy have also discovered many cases of COVID-19 patients with symptoms of swelling toes and discolored organs. Therefore, some doctors have started recommending people should get tested for COVID-19 when there are signs of redness in their feet.

What is the “COVID toes” treatment?

For people who don’t experience “many other symptoms, the condition tends to go away on its own, with no specific treatment,” says Dr. Freeman.

To reduce the discomfort caused by “COVID toes”, the patient can keep the feet warm like a lampshade, and wear socks.

If you notice a change in color on the skin of the foot or unusual signs around the toes, the patient should contact the nearest medical facility for a test for COVID-19. Since some other health conditions such as drug reactions or connective tissue disorders can cause similar symptoms, the patient should provide complete medical history with the medical staff practice.

With the complicated epidemic situation and no specific vaccine or drug yet, the prevention of COVID-19 is of utmost importance to minimizing the possibility of infection. This acute respiratory infection can leave many dangerous complications because the virus has the ability to affect the body in a far-reaching manner.

What are other skin symptoms of COVID-19?


The American Academy of Dermatology (AAD) said: “The possibility of skin changes in people with COVID-19 exists because other common viral infections have also been reported. However, these anomalies may not be recognized ”.

Doctors have shown signs of skin such as:

  • Bumps in the extremities and trunk, common when the body has a virus
  • Damage to blood vessels in the arms, legs and buttocks if the disease is severe
  • Gangrene (tissue death due to infection or lack of blood flow) in patients with severe symptoms and underlying medical conditions
