The most common signs that you are infected with a new corona virus are breathing problems. All members of the coronavirus family, and there are 40 species, affect the respiratory system, and SARS-CoV-2 is transmitted in addition to contact, including through airborne droplets. This means that when a person coughs or sneezes, tiny droplets of liquid from the nose or mouth that get into the air can contain the virus. But what happens to the body infected with CoVID-19? Despite the fact that the main blow hits the lungs, the process of the coronavirus seizing the body begins in the throat and 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 a virus looks like that changes our lives quickly

What is known about the new corona virus?

At the time of this writing, the number of people infected with the new corona virus has exceeded 400,000 worldwide. More than 18,000 people died and this number is growing every day. The World Health Organization (WHO) reported an accelerated spread of SARS-CoV-2 and the fact that the disease can be serious even in young people and children. Meanwhile, scientists are concerned about the novelty of the virus – the fact is that specialists don't know everything about it, and this makes it difficult to predict future events. Despite the fact that researchers around the world are developing a CoVID-19 vaccine and have started human trials in some countries, the zero patient – the person who was first infected – is still not found, just like the natural one Host of the virus. However, specialists were able to find out that the coronavirus attacks two specific cell groups in the lungs. Read more about how the lungs work and why they are needed in our material.

How does coronavirus cause infection?

CoVID-19 is transmitted through tiny, invisible drops when an infected person coughs or sneezes. These drops can fall on nearby people or land on a surface that touches others. This can potentially transmit virus particles from your hands to your eyes, nose, or mouth. As soon as the virus particles are in the throat and nasal passage, they bind to a specific type of receptor on the surface of the cells. Like any other form of life, the virus only wants to survive. To do this, however, he first has to copy himself.

Scientists around the world are developing a vaccine against coronavirus

The corona virus is bound to the cells and introduces its genetic material or its RNA into the cells. The cell metabolism (metabolism) is then recorded in order to create "replication factories" and reproduce as many copies as possible. Essentially, SARS-CoV-2 steals host cells.

RNA (Ribonucleic Acid) – These are molecules that are part of the cells of all living organisms and are involved in the work of genes. A gene is a hereditary factor that stores information about the signs and functions of every organism.

What does CoVID-19 do to the lungs?

When a virus multiplies, it triggers an immune response. When the immune system begins to resist, people develop symptoms because healthy tissue is previously damaged and inflamed. These symptoms include sore throat, runny nose, sneezing, coughing and sometimes fever. However, if the virus penetrates deep enough into the lungs, it can cause pneumonia, leading to shortness of breath and chest pain. A recovery phase follows for the majority of those infected. Most 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 that the virus can harm. In some people, infection causes the heart to beat irregularly and pump blood less rapidly, which may lead to heart failure. Since the virus can be swallowed, it can also infect intestinal cells. Since the virus broke out 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 blood and faecal samples.

The results of a new study showed that diarrhea and other gastrointestinal problems can be one of the first signs of CoVID-19. According to a study published in the American Journal of Gastroenterology, almost half of coronavirus patients went to doctors who complained about digestion. The authors looked at data from 204 patients in the Hubei province of China who had an outbreak of the coronavirus and found that 99 people 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 system recognizes the attack of such infectious agents as viruses. However, sometimes the immune system starts working against us and attacks the body cells. In some cases, this leads to the development of autoimmune diseases such as lupus, psoriasis and others. In the case of CoVID-19, the immune system recognizes the threat and then goes into an attack that it cannot control, causing damage to healthy tissue. As a result, the body's efforts to fight the virus can cause pneumonia, which can make breathing difficult. The fact is that after developing pneumonia, the virus can get into the alveolar air sacs in the blood vessels of the lungs. Alveoli are important for normal breathing because they support gas exchange. However, they are very sensitive and can limit the saturation of the blood with oxygen in the event of damage.

The new corona virus affects not only the lungs, but also the kidneys

In addition, the new coronavirus can also target the kidneys – these are two bean-shaped organs that filter toxins from the blood. Because of the corona virus, the kidneys are not working properly, which can lead to organ failure and death. The WHO recommends that people over the age of 60 or those with comorbidities such as cardiovascular diseases avoid crowded places to reduce the likelihood of infection with CoVID-19. Although young people can become seriously ill, older people are currently the most vulnerable group. Health.
