Introduction. The urgency of the problem is conditioned by the fact that according to COVID-19 information resource, the number of patients who had coronavirus infection from January till December 2020 amounted to 6,161,835, of them: 480,692 had moderate degree of severity, 110,178 had severe degree of severity, 78,669 had extremely severe condition, 5,492,296 had mild and other conditions. At present time according to WHO data not less than 10% of survived covidinfection suffer from complications [1]. According to the WHO, at least 10% of people who have had Covid-19 suffer from postvoid syndrome. About 40% of them complain of feeling short of breath, shortness of breath. Seventeen percent have a persistent cough. One in ten experience joint and muscle pain. Patients may also be disturbed by palpitations. One in five have a foggy feeling in the head or increased hair loss. And one in three patients experience sleep problems. 60% of patients after COVID-19 experience signs of asthenia (chronic fatigue syndrome), including muscle weakness. Another 4% suffer from dizziness, and 2% report numbness in the feet and hands. Abdominal pain, nausea, and diarrhea occur in 4% of patients [1]. Purpose to study ‒ the consequences of the disease in patients who had a new coronavirus infection. Materials and methods. Questionnaire, analysis, classification, comparison method, statistical processing methods. Results. As a result of the study, we were able to find out that women later than men begin to show signs of post-acute complications, and men have a harder period of rehabilitation immediately after the acute phase of the disease. We also managed to identify a correlation between the severity of the disease and postcoid syndrome. Patients who had the disease in a severe degree were more likely to experience symptoms of postcoidal sequelae than patients with a mild degree of severity. Analysis of the presence of sequelae in study subjects after 12 months or more revealed the presence of "postcoid syndrome" symptoms, which may suggest a long-term course of the new "covid tail" phenomenon, and requires longer follow-up of patients. Studies have shown that post-covid syndrome can affect the lives of a wide spectrum of people with COVID-19, from those with the acute form going mildly to those with the most severe disease. COVID-19 can affect multiple organs and affect a range of systems, including fatigue, shortness of breath, cardiac dysfunction, cognitive damage, and sleep disturbances. Discussion. The most frequently reported symptom by respondents is asthenia. Its occurrence and persistence may be due to the effect of the virus on nerve cells, as well as to hypoxia and the development of microthrombosis. The effect of SARS-CoV-2 on cognitive performance as well as the occurrence of post-coronary asthenia is a serious problem in both men and women. Weakness after coronavirus with associated headaches, drowsiness, and physical weakness can occur due to lack of oxygen due to lung damage. Unlike normal fatigue, post-coronary asthenia is a pathological condition and is not corrected by rest. Such a condition can lead to decreased performance, disruption of habitual activities, and set the stage for more severe mental and somatic disorders. Conclusions. COVID-19 is a multisystem disease, with a variety of symptoms. The development of ongoing symptomatic (subacute) and post-acute syndrome is independent of the severity of the disease. Persons with acute COVID-19 may have a variety of symptoms and may change over time. Post-covid syndrome is a dangerous condition that can affect a person's physical and psychological well-being.
