Scientists called the danger of the evolved coronavirus

Scientists from the University of Maryland (USA) have found out that the mutated coronavirus is better transported through the air. The study is published in Clinical Infectious Diseases.

The authors studied 49 cases of infection with different strains of SARS-CoV-2. In all patients, the disease was asymptomatic or with weak signs.

Scientists experimented with which volunteers with COVID-19 were asked to repeat the alphabet three times or sing “Happy birthday to you.” As it turned out, people infected with the alpha strain exhaled up to a hundred times more viral particles than those who had the “original” (Wuhan) version.

“We know that delta is even more contagious than alpha. Our study provides additional evidence for the transmission of new strains of infection by airborne droplets,” the researchers said.

Thanks to air monitoring, experts have also confirmed that medical masks reduce the risk of virus transmission by 50%. Therefore, to avoid infection, it is necessary not only to be vaccinated but also to continue to use personal protective equipment and ventilate the premises.

The World Health Organization has listed four SARS-CoV-2 mutations as “of concern”: strains “alpha” (British), “beta” (South African), “gamma” (Brazilian), and “delta.”

In recent months, the delta strain, first discovered in India, has become dominant in most countries, including Russia. Among its main features is a shorter incubation period than the previous varieties of the pathogen and an increased load on the human body.
