As per a new study led by a team of researchers at the University of Maryland School of Public health, people infected with the Alpha variant, which was first discovered in the United Kingdom, expelled 43 to 100 times more virus into the air than people infected with the original COVID strain.

To top that, researchers also found that loose-fitting cloth and surgical masks reduced the amount of viral particles released or exhaled into the air by the infected person by half.

According to Doctor Don Milton, professor of environmental health at the University of Maryland School of Public Health, “Our latest study provides further evidence of the importance of airborne transmission.”

“We know that the Delta variant circulating now is even more contagious than the Alpha variant. Our research indicates that the variants just keep getting better at travelling through the air, so we must provide better ventilation and wear tight-fitting masks, in addition to vaccination, to help stop spread of the virus,” he adds.
