know 4 strange symptoms of coronavirus

More than two years after the onset of the epidemic, hundreds of thousands of Covid cases continue to be reported worldwide every day.

With the emergence of new species, covid symptoms have also emerged.

Previously, for example, the UK National Health Service (NHS), SUS UK, considered fever, cough and loss or changes in smell or taste as major symptoms that could be a symptom of the disease.

Now, a recently updated NHS guideline also recommends that we stay alert for symptoms including sore throat, runny or runny nose and headaches.

But what about some of the more obvious signs and symptoms? From skin lesions to hearing loss, new studies are increasingly showing us that covid symptoms are not just for the flu or the flu.

1. Skin wounds

Covid-related skin problems are not uncommon. In fact, a British study published in 2021 found that 1 in 5 patients had only a rash and no other symptoms.

Covid-19 can affect the skin in many ways. Some people may have a maculopapular rash (flat, raised patches), while others may have hives (itching, raised patches).

The so-called “covid fingers” are characterized by red, swollen or blistered skin lesions on the fingers. This symptom is more common in adolescents or young people with mild or symptomatic symptoms.

Most covid-induced skin lesions usually disappear within a few days or, in some cases, without the need for any special treatment.

However, if the skin is itchy or very sore, it is advisable to see a doctor, who may recommend using a cream.

2. “Covid nails”

During infections, including SARS-CoV-2 (the virus that causes covid-19), our body usually tries to explain that it is under abnormal stress.

“Covid Nails” includes changes such as:

  • Beau Lines: These are horizontal elevations that occur under the nails or nails when there is a temporary stop in the growth of the nails due to physical stress on the body.
  • Leukonychia striatum: These are white horizontal lines visible on the nails, although this may be due to abnormal protein production in the nail bed.
  • The red crescent pattern develops under the nails (the mechanism that causes these changes is unknown).

Data on how many people have these nail problems are limited, but it is estimated that they can affect 1% to 2% of Covid patients.

“Covid nails” usually appear on the day or week after infection, when the nails grow. Although it can be painful at first, most nails tend to return to normal within a few weeks.

Although these changes may be a symptom of covid, they can also be caused by different factors. For example, Beau lines may be the result of chemotherapy or other infections.

3. Hair loss

Hair loss is probably an undiagnosed symptom of Covid-19, which usually occurs a month or more after acute infection.

In a study of nearly 6,000 people who contracted the new coronavirus, hair loss was the most common post-covid symptom, reported by 48% of respondents.

Hair loss was particularly prevalent among men with severe Covid and in white women.

This is believed to be because the hair “feels” stress on the body, causing excessive shedding.

In fact, hair loss can be triggered by other stressful events, such as childbirth. The good news is that over time your hair will grow back to normal.

4. Hearing loss and tinnitus (or tinnitus)

As with other viral infections such as the flu and measles, covid has been found to affect the inner ear cells, with hearing loss or tinnitus (a constant sensation in the ear) sometimes after infection.

In a study involving 560 participants, hearing loss was reported in 3.1% of covid-19 patients, while tinnitus occurred in 4.5% of cases.

In another study, with 30 people diagnosed with covid-19 and 30 who did not have the disease, no one had previous hearing problems, the researchers found that covid-19 was associated with damage to the inner ear, leading to frequent hearing problems. on. .

Although for many patients this is resolved by itself, cases of permanent Covid-related hearing loss have been reported.

Why do these symptoms appear?

We do not know exactly what causes these symptoms, but we do know that a very important role is played by a process called inflammation.

Inflammation is a natural process of protecting our body against pathogens; SARS-CoV-2 in this case. It involves the production of “cytokines” (also called cytokines), proteins that are essential for controlling the activity of immune cells.

Excessive production of these proteins, as part of the inflammatory process caused by Covid infection, can lead to dementia, which may explain why some people experience hearing loss and tinnitus.

It can also repair capillary networks, very small blood vessels that supply blood to organs, including the ears, skin and nails.

The symptoms we are describing here are not limited to covid infections. That said, if you detect any of these symptoms, you should be tested for covid, especially if you are in an area where the virus is circulating.

You may also want to consult your doctor, especially if the symptoms are getting worse or causing more discomfort. At the same time, be assured that many of these symptoms can improve over time.
