What does coronavirus do with the human body?

The most common signs thatyou may be infected with a new coronavirus, there are breathing problems. All members of the coronavirus family, and there are 40 species, affect the respiratory system, and SARS-CoV-2, in addition to contact, is transmitted, including by airborne droplets. This means that when a person coughs or sneezes, tiny droplets of fluid from the nose or mouth that enter the air may contain the virus. But what happens to CoVID-19 infected body? Despite the fact that the main blow falls on the lungs, the process of capture of the body by the coronavirus begins in the throat and the symptoms may not appear in the first stages. In this article, you will learn what happens to the body after infection with CoVID-19.

So under the microscope looks a virus that is rapidly changing our lives

What is known about the new coronavirus?

At the time of this writing, the numberinfected with a new coronavirus in the world exceeded 400,000 people. More than 18,000 people died and every day these numbers are growing. Thus, the World Health Organization (WHO) reported an accelerated spread of SARS-CoV-2, as well as the fact that even in young people and children the disease can be severe. Meanwhile, scientists are worried about the novelty of the virus - the fact is that specialists do not know everything about it, and this makes it difficult to predict further events. Despite the fact that researchers all over the world are developing a vaccine against CoVID-19, and in some countries human trials have already begun, the null patient - the person who became the first to be infected is still not found, just like the natural host of the virus. However, specialists were able to find out that coronavirus attacks two specific sets of cells in the lungs. Read more about how the lungs function and why they are needed, read in our material.

How does coronavirus cause infection?

CoVID-19 is transmitted through tiny, invisibledrops when an infected person coughs or sneezes. These drops can fall on people who are nearby or land on a surface that others touch, which can potentially transfer virus particles from your hands to your eyes, nose, or mouth. Once in the back of the throat and nasal passage, the viral particles bind to a specific type of receptor on the surface of the cells. Like any other life form, the virus just wants to survive. But for this he must first copy himself.

Scientists around the world are developing a vaccine against coronavirus

Being attached to cells, coronavirusintroduces its genetic material or RNA into the cells. Then it captures cellular metabolism (metabolism) in order to create “replication factories” and reproduce as many of its copies as possible. In essence, SARS-CoV-2 steals host cells.

RNA (Ribonucleic Acid) - These are molecules that are part of the cells of all living organisms and participate in the work of genes. Gene - This is a hereditary factor in which information is stored on the signs and functions of each organism.

What does CoVID-19 do with the lungs?

When a virus multiplies, it causes an immunebody reaction. As the immune system begins to resist, people develop symptoms as previously healthy tissues get damaged and inflamed. These symptoms include sore throat, runny nose, sneezing, coughing and, sometimes, fever. However, if the virus enters deep enough into the lungs, it can cause pneumonia, which leads to shortness of breath and chest pain. For the bulk of the infected, this period is followed by a recovery period. Most will really get better.

How does CoVID-19 affect other parts of the body?

But the lungs are far from the only part of the body,which the virus can damage. In some people, an infection causes the heart to beat irregularly and pump blood less powerfully, which could potentially lead to heart failure. Because the virus can be swallowed, it can also infect intestinal cells. Since the outbreak of the virus in December last year, digestive problems have been a common complaint among those infected. According to the Centers for Disease Control, the genetic material of the virus is often found in samples of blood and feces.

The results of a new study showed thatdiarrhea and other gastrointestinal problems may be one of the first signs of CoVID-19. According to a study published in the American Journal of Gastroenterology, nearly half of coronavirus patients went to doctors complaining of digestion. The authors examined the data of 204 patients in the Chinese province of Hubei, where there was an outbreak of coronavirus and found that 99 infected had symptoms such as diarrhea, vomiting and abdominal pain.

What happens to the immune system of CoVID-19 patients?

As described above, the human immune systemrecognizes the attack of such infectious agents as viruses. However, sometimes the immune system begins to work against us and attacks the cells of the body. In some cases, this leads to the development of autoimmune diseases, such as lupus, psoriasis, and others. But in the case of CoVID-19, the immune system recognizes the threat, and then goes into an attack that it can not control, which leads to damage to healthy tissues. As a result, the body’s efforts to fight the virus can cause pneumonia, which can make breathing more difficult. The fact is that after the development of pneumonia, the virus can go to the alveoli - air sacs in the blood vessels of the lungs. Alveoli are important for normal breathing, as they help gas exchange, however they are very sensitive and in case of damage can limit the saturation of blood with oxygen.

The new coronavirus affects not only the lungs, but also the kidneys

In addition, a new coronavirus may also betargets the kidneys - these are two bean-shaped organs that filter toxins from the blood. Due to the coronavirus, the kidneys do not function properly, which can lead to organ failure and death. WHO recommends that people over 60 years of age or people with concomitant diseases, such as cardiovascular diseases, avoid crowded places to reduce the likelihood of becoming infected with CoVID-19. Currently, although young people can also become seriously ill, older people are the most vulnerable group. Be healthy.
