Mask-wearing had no discernible impact on the spread of COVID-19 in Europe during winter 2020-21 and may actually have increased mortality, a study has found.
The peer-reviewed study by Professor Beny Spira from the Department of Microbiology at the University of São Paulo, published in the journal Cureus, looked at the correlation between the rate of mask-wearing in the population and the number of reported infections and deaths from October 2020 to March 2021 in 35 European countries. All European countries, including Western and Eastern Europe, with more than one million inhabitants were included, encompassing a total of 602 million people. All the countries experienced a peak of COVID-19 infections during the six months – the winter 2020-21 wave.
The results are shown in the graphs above, where a positive correlation can be seen in the case of both infections and deaths, i.e., greater mask-wearing went hand-in-hand with more infections and deaths, the opposite of the intended effect of masks. In the case of reported infections the correlation was not statistically significant, so may have been by chance. In the case of deaths it was statistically significant, particularly in Western Europe, opening up the possibility that wearing masks actually made things worse.
