A new study by Texas University of A and M has found that not wearing a mask puts people at great risk of contracting a new type of coronavirus, causing COVID-19- and increasing their chances of spreading the virus to others,media reported. Masks alone are not enough to prevent viruses, but they are an important tool.
In some countries, including the United States, wearing masks in public is controversial – a combination of false information and widespread stubbornness has fuelled a backlash against mask recommendations, leading many to visit shops and generally approach strangers without this form of protection.
In New York, Italy and China, the use of masks prevented tens of thousands of CASES of COVID-19 in just a few weeks, according to a study by the University of A and M. Respiratory aerosol particles are considered the “main” mode of transmission of the new coronavirus, and masks have been shown to be effective in protecting individuals from person to person.
Of course, maintaining social distance and other practices, such as washing hands frequently and avoiding touching your face, is also an important and necessary way to help protect against viral infections. In the end, masks are considered a cheap and efficient way to protect individuals at the individual level.
Study co-author Professor Mario Molina of the University of California, San Diego, said:
Our study makes it very clear that the use of masks not only helps prevent infected cough droplets from entering the uninfected body, but is also critical to these ine-infected people avoid inhaling tiny atmospheric particles (aerosols) that can stay in the atmosphere for tens of minutes and spread dozens of feet.
