Four skin changes caused by the Corona virus should be known


Since the beginning of the epidemic, health experts have documented fever, dry cough, and loss of the sense of taste and smell, as basic signs of Coronavirus infection.

Apart from the “classic three” signs, there were a number of less common side effects reported by those who tested positive, such as headache, muscle and joint pain, nasal congestion and fatigue.

Skin lesions in patients

However, one of the symptoms of the Coronavirus that has not attracted much attention is the variety of rashes that the disease can cause which appear all over the body.

Although a rash is less common than other symptoms, it is important to know how “Covid-19” can affect the skin so that you can identify a possible infection as soon as possible.

A recent study found that for 17% of “Covid-19” patients who suffer from more than one symptom, the rash was the first symptom to appear, while 21% of patients the rash was their only symptom.

The four main types of rashes that occur when infected with the Coronavirus are listed below, along with possible causes.

1- Frost ulcer-like lesions:

These types of skin abnormalities mainly affect the toes and the sole of the foot, which is why you may have heard about them under the simpler name “Covid toes”.

Scientists explain the symptoms

After one to two weeks after their first appearance, the lesions will become more variable in color but reduce swelling, before finally disappearing without treatment.

This type of red, swollen pimples has been detected more commonly among adolescents and young adults who do not have symptoms of “Covid-19” or have only mild symptoms. It is the most common skin problem associated with the virus.

It is important to note that there is no real, concrete medical evidence that can link skin lesions to direct infection with “Covid-19”, and frostbite-like lesions can appear as a result of a number of other diseases, although these lesions during the epidemic indicate that they are related With “Covid-19”, this has not been confirmed yet.

A study that analyzed 26 patients suspected of having skin changes linked to “Covid-19” found that 73% of the participants showed frost sore-like lesions. Surprisingly, none of the patients had respiratory symptoms and all of them tested negative for “Covid-19” at the onset of their lesions.

One theory suggests that the lesions are caused by damage to blood cells due to the body’s immune system response to a viral infection or multiple small blood clots in the toes.

2- Macular rash:

This type of rash causes flat, raised areas of discolored skin. And a Spanish study of 375 patients with skin changes linked to “Covid-19” found that 47% showed this type of rash.

This rash is associated with more severe symptoms of “Covid-19”, which are most often found in middle-aged to elderly people. The condition usually lasts 7 to 18 days, and appears 20 to 36 days after infection.

As with the ulcer-like lesions of the fingers, a maculopapular rash can be caused by the body’s immune system which is actively fighting the infection. In some cases, the hyper-inflammatory phase begins 7-10 days after infection, which in turn leads to tissue damage and, in the worst cases, disease and death more severe.

3- Urticaria:

Urticaria are raised areas of the skin that often itch and irritate. And when it comes to “Covid 19”, it usually precedes urticaria or appears at the same time with other symptoms, which makes it easy to recognize it as a symptom of the coronavirus.

It is more common in middle-aged patients and is associated with more severe disease. Urticaria appears after infection because it causes cells to break down, which then releases histamine through the immune system.

The drugs used to treat “Covid-19” can also cause hives, such as corticosteroids and remdesivir.

4- Vesicular lesions:

Vesicular lesions visually resemble chickenpox, which are clear fluid-filled sacs that form under the skin. With regard to the coronavirus, vesicular lesions are the most common types of rashes, as the previously mentioned Spanish study showed that only 9% of patients with “Covid-19” showed these lesions.

It often appears in patients with mild disease about 14 days after the initial infection. It results from a prolonged period of inflammation, as antibodies attack the skin and damage its layers, resulting in fluid-filled sacs.
