one should probably distinguish between infection (virus carrier) and disease. Once in the body, infection may not cause significant harm. those. the virus carrier is infected with a virus, and can infect others, but not actually get sick. Then those who get sick have a latent (latent) period, while the virus multiplies enough to cause significant harm (show symptoms). Coronavirus has a latency period of up to 2 weeks. In both cases, the carrier is infectious. This is the danger (severity) of infection. More details can be found at Semin's

The complexity of the course of the disease and therefore the manifestation of symptoms depends on various factors:

  • firstly, from the viral load (i.e. the number of viral particles that have entered the human body), respectively, the more, the more difficult it is for the body to cope;

  • secondly, on the degree of readiness of the body to overcome the infection (i.e., on the level of immunity);

  • age also matters. The older a person is, the more protein is expressed in his body, which helps the penetration of the virus into cells.

Thus, a person can have viral particles in the body (and the PCR analysis will show their presence), but they will not have a negative effect on the body sufficient for the manifestation of clinical symptoms.

Well, what about the symptom about the absence of smells, now everyone is panicking, who has lost their scent, and this may have different reasons, In addition, the concept of smell is very individual. There are people who lose their sense of smell after hitting their heads hard. And as for the asymptomatic, it is scary to imagine how many hidden infections and fungi live in us, which we do not even know about, because there are no symptoms. And then again, and why did I have dandruff there, or why my cold popped up there. For example, no one thinks about why it is impossible to swim in some water bodies, for example, where there are ducks, but that it is an indirect fact that they are carriers of parasites that live "off" the ducks. And then they hang out by the shore, where our kids splash around. And now the leg is combing.

During the contact of the body with viruses, the so-called T-immunity is formed, which inhibits the spread and copying of the virus in the body until permanent immunity is formed. T cells are not as aggressive to the virus, rather friendly dogs are not allowed into the house, so there are no obvious signs of such as fever, runny nose, pain, etc.
