New study explains why Delta is so easily transmitted and infects people quickly

Wed, 10/27/2021 - 10:51
The Delta variant of SARS-CoV-2 has swept the globe, becoming the dominant variant within just a few months. A new study from Boston Children's Hospital, published today in Science, explains why Delta is so easily spread and infects people so quickly, and suggests a more targeted strategy for developing future COVID-19 vaccines and treatments.

How can we predict the number of future COVID-19 hospital admissions?

Wed, 10/27/2021 - 10:35
Research led by Sophie Meakin of the London School of Hygiene & Tropical Medicine in the United Kingdom suggests ensemble forecasts — a method combining multiple models to predict COVID-19 cases — may be more accurate in estimating COVID-19 hospital admissions in local areas.

Study shows sustained deterioration of mental health in UK across COVID pandemic

Wed, 10/27/2021 - 10:18
To date, it is not clear how the COVID-19 pandemic and implementation of various preventive strategies impacted mental health or which group of people were most affected by them. To address these issues, scientists have conducted coordinated analyses that included eleven UK longitudinal population studies, comprising data from before and throughout the pandemic.

Wed, 10/27/2021 - 09:08
Researchers in the United States have conducted a study showing that Moderna’s coronavirus disease 2019 (COVID-19) vaccine provided durable protection against the B.1.617.2 (delta) variant of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) in rhesus macaques.

Cholesterol-lowering drugs not helpful in reducing COVID-related mortality or severity

Wed, 10/27/2021 - 09:01
In the worldwide effort to battle SARS-CoV-2, the virus that causes COVID-19, researchers have often turned to medications used as therapies for other conditions in the hopes of finding ones that either kill the coronavirus or lessen the impacts from its infection.
