Mask wearing has never been seen as more essential to stopping coronavirus from spreading."A new long-term forecast predicts a significant increase in Covid-19 deaths in the U.S. by the new year," reports Bloomberg."Under the latest projections from the Institute for Health Metrics and Evaluation at the University of Washington's School of Medicine, Covid-19 deaths could rise to 410,451 by the end of 2020.
While most experts strongly encourage everyone—even those showing no symptoms of COVID-19—to wear a protective face mask while out in public in order to prevent the spread, there are still people who refuse to do so. However, a new study offers evidence that mask-wearing can dramatically reduce the non-contact transmission rate of the highly infectious and potentially deadly virus.
"In our hamster experiment, it shows very clearly that if infected hamsters or humans—especially asymptomatic or symptomatic ones—put on masks, they actually protect other people. That's the strongest result we showed here," Dr. Yuen Kwok-yung, a leading microbiologist from the university and leader of the study, explained.
In the third scenario, when no masks were used at all, ⅔—66.7%—of the hamsters were infected with COVID-19 within a week. When the barrier was placed over the cage housing the infected hamsters, the rate of infection plummeted to 16.7%.
