Purpose of research. To assess risks of infection COVID 19 in process of sport activities and to study influence of economics and demographic indicators and level of vaccination spread on area and speed of COVID-19. Background. To overcome the epidemic of COVID-19, it is important to study the dynamics of indicators that characterize the epidemiological process. Material and methods. We analyzed the indicators of 100 countries of the world, which on 03/25/2020 topped the rating by the number of infected people in the country. There were analysis and synthesis of literature, Internet resources, statistical methods among research methods. Results. It was found that the economic and demographic indicators of the country do not affect the incidence of COVID-19 however affect on the proportion of population coverage with vaccinations. At the beginning of the study (03/25/2020), in countries with higher economic and demographic indicators, the spread of coronavirus occurred at a slower pace, but now (11/14/2021) the economic and demographic indicators do not affect the country's place in the ranking by the number of infected. The increase in the number of infected and the death rate from coronavirus in the world leads to an increase in the amount of vaccine used. Conclusions. It has been proven that an increase in the number of used vaccines leads to a decrease in the country's place in the ranking in terms of the number of infected. Vaccination is an effective measure to stop the spread of infection in the world.
