Epidemiological features of covid-19 and post-covid complications.

Abstract

COVID-19 remains one of the most significant global medical and social challenges of the 21st century, significantly impacting morbidity, mortality, and quality of life. This article examines the epidemiological characteristics of COVID-19 spread, the dynamics of incidence, and the factors determining the severity of the infection. Particular attention is paid to post-COVID syndrome as a new epidemiological phenomenon characterized by the prolonged persistence of clinical symptoms after the disease. The main clinical and epidemiological manifestations of post-COVID complications, their prevalence among different age and social groups, and the impact of comorbidities are analyzed. The medical and social consequences of COVID-19 are highlighted, including decreased work capacity, increased burden on the healthcare system, and the need to develop comprehensive rehabilitation measures. The study results highlight the relevance of further study of post -COVID conditions and the improvement of preventive and treatment strategies.
