It can be noted from the presented data (Table 1) that there is no unambiguous dependence of morbidity and detail indicator on population density.
Experience with the COVID-19 pandemic since 11 March 2020 shows that countries that introduced severe restrictive measures early in the epidemic have significantly reduced or stabilized their infection (morbidity) rates. Such countries include China, Russia, Germany, Norway (morbidity per 100,000 population < 300 people), and the countries that followed a ”liberal approach” to restrictive measures had morbidity rates above 300/100,000 population (Italy, Spain, United Kingdom). The absence of practically restrictive measures has led to a significant increase in the incidence of diseases, as happened in Sweden (>1,000/100,000 population).
There are other reasons for fluctuations in the incidence rate. These include the loyalty of the population to the authorities, the implementation by the vast majority of the population of measures aimed at preventing the spread of infection. The need for mandatory implementation of recommendations by citizens should be accompanied by informing the population about the causes of the spread of infection and possible consequences of the disease. It is important to have truthful information based on the opinions of medical scientists, the maximum exclusion of pseudo-scientific, previously false information about the infection. The third aspect of this problem is the development of a control system and analysis of the implementation of restrictive measures. The state solves this issue in different ways and there can be no right recipes for everyone.
In addition, long-term restrictive measures of isolation of citizens cause fatigue, which leads to disregard for social distances, wearing masks.
Rating of countries on the number of deaths from coronavirus infection as of 18.04.2020 led the U.S., Britain, Italy, France, Spain, but in calculating mortality - the situation is different. Belgium (16.37%), France (16.64%), Great Britain (14.17%), Italy (14.15%), Hungary (13.07%), Netherlands (12.90%), Sweden (12.21%), Spain (11.95%), Mexico (10.52%), USA (5.1%), Germany (3.07%), Brazil (6.3%), Turkey (2.16%), China (5.46%), Norway (1.31%), Russia (0.94%).
