Fever, Cough, breath breathless - These are all considered as the main symptoms that have become universally associated with Covid-19. However, according to new research, there is another sign of diagnosis of the scary virus that infected nearly 14 million people around the world and the experts insist, the "fourth key symptom" of the virus should be considered.

In a newPre-printed studyLed by King's College London College, cutaneous rashes and redhead bumps must be added to the list of official coronavirus symptoms. These skin manifestations can not only occur in conjunction with other symptoms, but also in the absence of one of them.

Researchers used data of 336,000 people who submitted information via the COVID-19 symptom study application, noting that 8.8% that have been positive for COVID-19 reported a rash reported as a symptom. Even more interesting is that 17% of them reported a rash as a first symptom of the disease. In addition, for 21% of the positive people of COVID who reported a rash, it was their only symptom.

"Cutaneous eruptions with other COVID-19 symptoms are predictive of a positive cylinder test and occur in a large number of cases, only or before other conventional symptoms," explains the authors of the study , exhorting that they are added to the official list of symptoms. "Recognize skin rashes is important to identify new and past COVID-19 cases."

"Many viral infections can affect the skin. It is therefore not surprising that we saw these skin rashes in Covid-19," the main author Mr. Veronique Bataille, Dermatologist Consultant at the Saint-Thomas Hospital and the King's College London explained in thePress release. "However, it is important that people know that in some cases a rash can be the first or unique symptom of the disease. So if you notice a new rash, you must take it seriously by insulating and testing as soon as possible possible. "

The researchers said that there are three types of common skin manifestations of coronavirus:

Doctors call it: urticaria.

The first type of eruption is like hives, a "sudden appearance of raised bumps on the coming skin and that go very quickly above the hours and are generally very demoluted," they write. "This can involve any part of the body and often starts with intense itching of palms or soles and can cause swelling of the lips and eyelids. These rashes can come pretty early in infection, but can also Live long after. "

The doctors call it: erythemato-papular rash or erythema-vesicular.

The second type may seem similar to chicken chickenness. "Zones of small red bumps that can occur anywhere on the body, but especially elbows and knees as well as the back of the hands and feet. The eruption can persist for days or weeks", He explains.

Doctors call it: Chilblains.

The toes of Covid have been identified early in the pandemic and the researchers explain that they are characterized by "reddish bumps and violates on the fingers or toes on the fingers or toes, which can be painful but which does not generally . This type of eruption is the most specific to Covid-19, is more common in younger people with the disease and tends to appear later. "

"These results emphasize the importance of keeping an eye on the new changes in your skin, such as logs, bumps or rashes," said Dr. Justine Kluk in the press release. "Anticipated rating of cutaneous eruptions associated with Covid by members of the public and recognition of their importance by front-line health practitioners ... can increase the detection of coronavirus infections and help stop propagation."
