Background. The COVID-19 pandemic is a global pandemic caused by the SARS-CoV-2 coronavirus. The outbreak was first recorded in Wuhan, China, in December 2019. On January 30, 2020, the WHO declared the outbreak a health emergency of international significance, and on March 11, 2020 – a pandemic. In Ukraine, Covid-19 coronavirus infection (a new type of pneumonia) was first diagnosed on March 3, 2020, in Chernivtsi. On March 13, the first fatal outcome of Covid-19 was recorded. The purpose of the study was to analyze information sources for the last year. Materials and methods. The research used methods of semantic evaluation of scientific documents, as well as methods of structural and logical analysis. Results. The COVID-19, formerly a coronavirus infection 2019 nCoV is a potentially severe acute respiratory infection caused by coronavirus SARS-CoV-2 (2019 nCoV) and is a dangerous disease that can occur in the form of acute respiratory viral infection of mild and severe form. Studies suggest that the virus is the result of recombination of bat coronavirus with another, as yet unknown, coronavirus. At the same time, scientists from the United States concluded that SARS-CoV-2 has a genetic trace that is not observed in natural coronavirus. They said that it is founded evidence of artificial origin of the coronavirus. In 2021, the WHO changed the labeling of coronavirus strains, including four strains of concern and known to the public as options first discovered in Britain (Kent) (B.1.1.7), South Africa (B.1.351), Brazil (P.1) and India (B.1.617.2). From now on, the WHO recommends, labeling them using the letters of the Greek alphabet, ie - Alpha, Beta, Gamma and Delta, respectively. The most common symptoms of the Covid-19 coronavirus infection are fever, dry cough, shortness of breath, severe fatigue, muscle aches, sore throat, headache, loss or disturbance of taste and/or odor (characteristic symptom). Less common symptoms are diarrhea, conjunctivitis, skin rash, or discoloration of the fingers and toes. Symptoms that may occur with a severe course of SARS-CoV-2 infection: difficulty breathing or shortness of breath, chest pain or chest pressure, impaired speech or motility. To diagnose COVID-19 coronavirus infection is possible only having carried out necessary testing methods, namely: PCR, determination of coronavirus RNA SARS-CoV2 (COVID-19); IgG antibodies, coronavirus SARS-CoV-2 (COVID-19); IgM antibodies, coronavirus SARS-CoV-2 (COVID-19); IgA antibodies, coronavirus (SARS-CoV-2); Rapid test, coronavirus SARS-CoV-2, antigen, etc. There are two ways to acquire immunity: get sick or get vaccinated. There are more than 80 human vaccine studies in the world, although some are in the early stages of clinical trials. At the same time, companies whose vaccines are already in use around the world have begun to study updated versions of drugs that should be effective against new strains of the COVID-19 virus. Conclusions. Now, it is necessary to radically change the approach to combating the COVID-19 epidemic in 2021-2022. Priority should be given to early detection and containment of COVID-19 coronavirus infection outbreaks (testing, contact tracking, isolation) and a vigorous immunization campaign against ­COVID-19. Investigate the impact of the COVID-19 epidemic on the loss of human capital: lost services (forgone care), excessive mortality, additional burden of morbidity, in particular for chronic diseases. Direct resources to renew programs to increase the availability of health services. The increase in system load through the COVID-19 vaccination program should be considered.
