In this study, scientists from the University of Mona and Edinburgh have analyzed the analysis published so far on the effectiveness of certain measures that have been applied since the beginning of the pandemic, concluding that the use of masks reduces the incidence of kovid by 53 percent.

In addition, this measure also reduces the number of deaths from covid 19, as well as the transmission of the Sars-Cov-2 virus.

“A natural experiment in 200 countries showed that countries where wearing a mask was mandatory had a 45.7 percent lower mortality rate associated with covid,” the study said.

Physical distance was 25% less effective in reducing the incidence rate.

The researchers also said that hand washing reduced the incidence rate by 53 percent, with this percentage based on analysis of studies involving fewer respondents.

As for other applied measures, the researchers said that previous studies have shown that isolation, minimization of contacts, periods of closure of all non-essential activities have led to a significant reduction in the number of patients. and dead.

However, as they note, general closure is not sustainable and more specific measures are needed that do not endanger social life and the economy and protect the health of citizens.

At the same time, the study authors warn that, as long as collective immunity is achieved, preventive measures remain the first choice in disease prevention, especially in areas with a small percentage of vaccines.

In most European countries, the use of masks is mandatory at home, and even countries that have abolished the measure before, such as Denmark, are returning it now due to an increase in the number of patients.
