A recent and comprehensive analysis by American and Canadian experts found that at least 35% of people infected with the novel corona virus (SARS cocoa 2) do not show symptoms.
It should be noted that the estimates made so far about people infected with the corona virus without any apparent symptoms are very vague, with rates ranging from 20% to 80%.
The purpose of this study was to remove the ambiguity in which the results were obtained after a comprehensive meta-analysis of 350 studies of two different types.
In one of these studies, people who were initially tested had the corona virus but no symptoms. However, a few days later, they showed some symptoms of corona virus. This rate was 36.9%.
The second type of study included people who tested positive for the corona virus but did not show any signs of being infected. This number was 35.1%.
Regardless of whether Corona infected people later showed symptoms of Covid 19, a total of 40% of those infected did have Corona virus at the time of the first test but did not show any symptoms.
Experts say that the results of this analysis should not be considered final because the global situation of corona virus is constantly changing. So far, however, his analysis has been largely credible.
