COVID-19 virus evolves to “improve” in moving through the air – SPOTLITER NEWS

New mutations of COVID-19, like the Delta strain, are “improving” in airborne transmission, a study he found.

According to the University of Maryland School of Public Health, people infected with a later variant of COVID-19 release 43 to 100 times more viruses into the air when they breathe than those infected with the original strains of the virus.

The researchers also found that loose clothing and surgical masks cut the amount of virus entering the air around infected people by about half.

‘Our research indicates that variants continue to improve at air travel,’ said Professor Don Milton, ‘so we need to provide better ventilation and wear tight-fitting masks, in addition to vaccination, to help stop the spread of the virus. “

The newly published study looked at the Alpha strain, which has since been replaced by the more dominant and even more highly transmissible Delta variant.

The study found that the amount of virus in the air from Alpha variant infections was 18 times greater than what could be explained by the increased amount of virus in nasal swabs and saliva, highlighting the dangers of tiny aerosols they carry. the infection.

“We know that the Delta variant circulating now is even more contagious than the Alpha variant,” Dr. Milton warned.

To test whether face masks work in blocking the virus, the study measured how much SARS-CoV-2 was breathed in the air and tested at least virus people with COVID-19 exhaled into the air after wearing a cloth or surgical mask.

The face coverings significantly reduced virus-laden particles in the air around the infected person, reducing the amount by about 50 percent, the researchers found.

Unfortunately, the loose cloth and surgical masks did not prevent the infectious virus from entering the air, according to the study.

“The take-home messages from this article are that coronavirus may be in your exhaled breath, it is getting better at being in your exhaled breath,” said Dr. Jennifer German, co-author of the study.

“Using a mask reduces the chance that you breathe it on others.”
