The World Health Organization (WHO) published in a new technical study that the suggestion of using face masks to combat diseases such as COVID in open and ventilated environments is of little importance or even almost useless.
The conclusion comes after several studies that showed that masks were inefficient in open environments, as contamination by the COVID-19 virus occurs through the air and that the type of mask completely influences its usefulness. Ordinary masks like those used during the pandemic were unable to stop the virus.
New WHO research now understands that the virus has a continuous spectrum of sizes smaller than the pores of common mask cloths. This raised doubts about the effectiveness of masks, especially when used indiscriminately in outdoor and ventilated environments, which characterize the least amount of contamination.
Another conclusion of the study is that contamination by touch, which in 2021 they were considered as 1 in every 100, today they are considered negligible. The coronavirus is an airborne virus, it has never been transmitted by touch.
In Canada, sales of alcohol gel in the first week of March 2020 increased by 792% compared to 2019. The explosion in demand was also recorded in the United Kingdom (255%), Germany (751%) and the United States (485%) . In France, the most sold brand saw a 700% increase in the price of the product.
In June 2020, the WHO changed its guidelines regarding the use of masks and stated that everyone should wear masks in public to avoid contagion. The Organization stated that at that time it had obtained sufficient data that proved the usefulness of using masks to prevent the spread.
At the time, there were those who belittled the disease and there were fervent defenders of the unquestionable effectiveness of these items. In different parts of the world there were fines and coercion against those who questioned and “rebelled” against the health authorities. In cities in the United Kingdom there were fines for those who ran without a mask and in Brazil people on the beach were fined for not wearing a mask.
All this information, admitted by the WHO in 2024, had already been defended through a study by aerosol specialist Lindsey Marr, from the public university Virginia Tech in 2021. The study was met with resistance and was ignored at the time.
