Abstract
Suppurative diseases of the lungs are topical issues of pulmonology that require detailed study due to the difficulties of diagnosis and high mortality of patients. This is due to a number of objective and subjective reasons, in particular, such as the widespread use of antibiotic-resistant microflora, which is especially important when antibiotics are prescribed unreasonably, even with a mild form of COVID -19. This, of course, affects COVID patients, who already have reduced immunity. The question of the exact mechanism of development of purulent complications of the lungs after or during infection with COVID -19 remains open. Clinical and radiological signs of a lung abscess often resemble the symptoms of pneumonia, however, antibacterial and symptomatic therapy have differences. With gangrene of the lung, the increase in intoxication syndrome can be gradual, which reduces the doctor's alertness regarding the most severe disease and causes inadequate therapy. Comprehensive diagnostic measures, knowledge of the main clinical, instrumental and laboratory parameters are necessary for all physicians.
