A newly published animal study found that chronic alcohol consumption may create conditions in the body that can facilitate infection by SARS-CoV2, the virus that causes COVID-19 disease. The study, published in Alcohol: Clinical and Experimental Research, found that chronic alcohol use increased the levels of an enzyme that helps the virus enter the cells and, therefore, may increase the risk for COVID-19.

Researchers tested lambda’s effectiveness using a randomized placebo-controlled trial involving adults with COVID-19 from both Canada and Brazil, who freely volunteered for the study. A total of 931 people received lambda and 1,018 received a placebo. Eighty-three per cent of the trial participants were vaccinated. Researchers ran the lambda trial from June 2021 to March 2022.

Spike proteins are one of the main targets for COVID-19 vaccines and treatments. But those remedies gradually lose effectiveness when the spike proteins mutate. Now, researchers report in ACS Central Science that they have discovered small molecules that target other segments that mutate less.

Researchers recently modeled the transmission of COVID-19 within an isolation room at the Royal Brompton Hospital in London, U.K. Their goal was to explore the optimal room layout to reduce the risk of infection for health care staff. To accomplish this, they used an adaptive mesh finite-element computational fluid dynamics model to simulate 3D spatial distribution of the virus within the room — based on data collected from the room during a COVID-19 patient’s stay. They share their findings and guidance in Physics of Fluids.
