Analysis of world literature data on the prevalence of SARS in the world, the taxonomy of pathogens, analysis of data from various institutions.

an acute respiratory infectious disease caused by the SARScoronavirus (SARS-CoV). Clinically, it is characterized by fever, headache, muscle soreness, fatigue, dry cough, rarely with sputum, and diarrhea. Most patients have concomitant pneumonia. In severe cases, these conditions can develop into acute lung injury, acute respiratory distress syndrome (ARDS), or even multiple organ failure, which leads to death.

0.5-1%. Using modern models of infection mortality rates depending on age, the upper and lower limits of infection rates in Germany can be estimated in the range from 0.4 to 1.6%, which is lower than in most European countries SARS-CoV-2 is a newly emerged coronavirus. Infections in humans were first detected in late 2019 in Wuhan, China. In the following months, the virus spread rapidly around the world. SARS-CoV-2 reproduces mainly in the upper and lower respiratory tract and is highly infectious. Droplets and aerosol are the main transmission routes, and infection also occurs through asymptomatic infected individuals. Almost 90% of cases proceed without complications, in a minority of cases severe diseases and complications occur. Risk factors for the development of severe diseases are old age, hypertension, diabetes mellitus, chronic heart or lung diseases and immunodeficiency.

influenza A viruses. (A) Epidemics of SARS-CoV-2, SARS-CoV, MERS-CoV, and influenza A viruses. The timeline, natural reservoirs, total number of deaths, and symptoms of the patients infected with these viruses. (B) Cumulative numbers of cases and deaths caused by SARS-CoV-2, SARS-CoV, MERS-CoV, and influenza A (during the last seasonal flu 2019–2020) viruses. Influenza A virus infected the most people, while SARS-CoV-2 caused the most deaths. (C) Case-fatality rate (CFR) of patients infected with SARS-CoV-2, SARS-CoV, MERS-CoV, and influenza A (the last seasonal flu 2019–2020) viruses stratified by age.

atypical nature of the disease, the medical community was able to develop timely methods for identifying the pathogen, treatment aimed at preventing or minimizing complications, as well as a vaccine against the new SARS virus.

supervisors PhD, associate Professor ), Department of Microbiology, Virology, Immunology] for giving me an opportunity to present my thesis on PATHOGENES OF ATYPICAL PNEUMONIA- SARS COV, MERS-COV, SARS COV 2 to the scientific society.
I also give thanks to the Department of microbiology OrGMU for engaging students of foreign faculty in these activities in order to increase the exposure of their hidden ideas to the front. This has given a native student like me a chance to bring about the latest updates about the disease in our country and measures taken up by them
