Abstract: Pneumonia is a disease that has an acute course and is characterized by an infectious and inflammatory lesion of the lungs. The high level of one-stage morbidity of community-acquired pneumonia, mainly in the variant of severe and life-threatening course in combination with concomitant pathology (75.4%), causes significant damage to the health of the population and deaths are observed in 6.7%. The problem of manifestations of long-term results of pneumonia is becoming increasingly relevant today in connection with the sharply increased rate and intensity of working activity of people, improving the quality of work, as well as environmental pollution and concomitant pathology also leaves its mark on human health. In case of community-acquired pneumonia, the concomitant pathology will influence the long-term results, further observation of these patients will show for 2, 3 years, depending on the severity of the course.
