More contagious offshoot of Delta coronavirus variant found in UK?

The scientists are closely watching a new mutation of the Delta variant by name AY.4.2. As per reports, the scientists of INSACOG said that it has also been found in India in very low numbers.

The new variant has been declared as a “Variant Under Investigation (VUI)” (VUI-21OCT-01) in the UK. And, the scientists say that the new variant may be more transmissible than the Delta strain.

“The designation was made on the basis that this sub-lineage has become increasingly common in the UK in recent months, and there is some early evidence that it may have an increased growth rate in the UK compared to Delta,” the UK health security agency said.

“More evidence is needed to know whether this is due to changes in the virus’ behaviour or to epidemiological conditions,” the UK health security agency said.

Airborne transmission of Covid-19 random, social distancing alone not enough to control spread: Study

A new study new study has shown that the airborne transmission of Covid-19 is highly random and suggests that social distancing alone is not effective in controlling its spread, reiterating the importance of vaccination and face masks.

“One part of the way that this disease spreads is virology: how much virus you have in your body, how many viral particles you expel when you speak or cough,” said Dr Shrey Trivedi, the Indian-origin first author of the study published in the journal ‘Physics of Fluids’ this week.

“But another part of it is fluid mechanics: what happens to the droplets once they’re expelled, which is where we come in. As fluid mechanics specialists, we like the bridge from virology of the emitter to the virology of the receiver and we can help with risk assessment,” explained Trivedi from the Department of Engineering at the University of Cambridge.

Air pollution linked to increased risk of getting sick from Covid-19: Study

Published

By

According to a study conducted in Spain, long-term exposure to air pollution is associated with an increased risk of developing Covid-19 among people who get infected with the SARS-CoV-2 virus.

The research, published in the journal Environment Health Perspectives on Wednesday, provides further evidence on the health benefits of reducing air pollution, and highlights the influence of environmental factors on infectious diseases.

“The problem is that previous studies were based on reported cases, which had been diagnosed, but missed all the asymptomatic or undiagnosed cases,” said study first-author Manolis Kogevinas from Barcelona Institute of Global Health (ISGlobal) in Spain.
