Defeat of the blood system after COVID-19 in general medicine practice

Coronavirus infection is an acute viral disease transmitted by airborne droplets. It was one of the first to be described in 1975 in a patient suffering from acute rhinitis. The causative agents of the disease are a family of RNA-containing coronaviruses. Within the family, there are several groups of infectious agents that are dangerous to the human body: human coronavirus 229 E, human OS-43 virus and human intestinal coronaviruses. The pathogen is quite unstable in the environment, and its effects can be eliminated with the help of disinfectants and exposure to high temperatures. Basically, HIV-infected patients, children, patients with severe chronic diseases (diabetes mellitus, oncological processes) are considered to be at risk for the incidence of atypical coronavirus pneumonia. After entering the upper respiratory tract, the coronavirus actively multiplies and epithelial cells are destroyed. If the immune system is poorly developed, then the coronavirus can penetrate into the alveoli, the process of replication of the pathogen occurs in their cytoplasm. By exocytosis, ready-made virions lie on the outer membrane of cells, which activates the fusion of epithelial cells and accelerated syncytium formation.
