COVID-19 can be mild or without any signs of infection. Despite the asymptomatic course of the disease, the patient is quite dangerous to others.

How does asymptomatic coronavirus proceed?

The head of the Department of Pulmonology, S. Avdeev, noted that the frequency of latent cases is up to 30% of all infected. A person can be infected, but at the same time not suspecting what danger he brings to others.

COVID-19 enters the body most often through the respiratory tract. Once in the body, the virus begins to multiply, and its particles circulate through the blood.

After infection with SARS-CoV-2, events can develop as follows:

• in people with strong immunity, the pathogen is contained by the immune system, neutralizing it. In this case, during the fight against the virus, no symptoms may appear until the moment of recovery;
• in some patients, the asymptomatic course of COVID-19 can lead to the development of latent pneumonia. At the same time, typical signs of the disease (cough, shortness of breath) are not observed, but during the passage of CT, foci of damage are found;
• there are no manifestations at the stage of the incubation period. At this time, a person will consider himself completely healthy, and only then the primary signs will appear (body aches, weakness, headache).

To confirm the diagnosis, you will need to be tested for the presence of coronavirus infection. It is recommended to be tested 2 times a month to exclude latent course.

Danger of asymptomatic passage of the disease

COVID-19, no matter how it proceeds, can have serious consequences. For example, if the so-called fibrosis is recorded on CT, this can subsequently lead to the development of various diseases.

With an asymptomatic course of the disease, the virus remains dangerous not only for the patient, but also for others. Therefore, it is important to observe precautions and be in self-isolation during this period.

According to Sergei Babak, professor of the Department of Phthisiology and Pulmonology of the Faculty of Medicine of Moscow State Medical University, patients who do not have visible symptoms of coronavirus infection tolerate it more easily, which means that the risk of further complications decreases.

Felix Ershov, chief researcher at the Research Institute of Epidemiology and Microbiology, believes that thanks to asymptomatic patients, the population will develop collective immunity faster. By spreading the infection in a mild form, "collective immunization" occurs without losses and complications. In his opinion, only after more than 80% of people on earth fall ill, the pandemic will be stopped.

Outcomes

• an asymptomatic course of the disease gives the patient a chance for an easier course of the disease and no consequences;
• during such a period, the patient is dangerous to others, since he, without suspecting that, spreads the infection everywhere;
• it is recommended to be tested for Covid-19 at least 2 times a month in order to reveal the latent course of the disease.
