New Delhi: People across the globe are trying their best to prevent themselves from the virus. Wearing masks and using sanitisers has become a part of our day-to-day lifestyle and a recent study has proved that wearing masks or covering your face may have prevented tens of thousands of infections. Mask-wearing is even more important for preventing the virus' spread and the sometimes deadly Covid-19 illness it causes than social distancing and stay-at-home orders, researchers said, in the study published in PNAS: The Proceedings of the National Academy of Sciences of the USA. Infection trends shifted dramatically when mask-wearing rules were implemented on April 6 in northern Italy and April 17 in New York City - at the time among the hardest-hit areas of the world by the health crisis - the study found. "This protective measure alone significantly reduced the number of infections, that is, by over 78,000 in Italy from April 6 to May 9 and over 66,000 in New York City from April 17 to May 9," researchers calculated. When mask-wearing went into effect in New York, the daily new infection rate fell by about 3% per day, researchers said. In the rest of the country, daily new infections continued to increase. Direct contact precautions - social distancing, quarantine and isolation, and hand sanitizing - were all in place before mask-wearing rules went into effect in Italy and New York City. But they only help minimize virus transmission by direct contact, while face-covering helps prevent airborne transmission, the researchers say. "The unique function of face-covering to block atomization and inhalation of virus-bearing aerosols accounts for the significantly reduced infections," they said. That would indicate "that airborne transmission of COVID-19 represents the dominant route for infection." The U.S. Center for Disease Control and Prevention on Friday urged organizers of large gatherings that involve "shouting, chanting, or singing to strongly encourage the use of cloth face coverings to lower the risk of spreading the coronavirus."
