Exploring the kinetics of SARS-CoV-2 Marseille-4 variant

In a new study, researchers determined the nature and dynamics of mutations associated with the SARS-CoV-2 French Marseille-4 variant during 10 months from its onset, and concluded that the heterogenicity associated with a SARS-CoV-2 lineage can possibly predict the end of an outbreak.

Scientists employ AI to predict which viruses could infect humans in future

Daniel Becker, an assistant professor of biology in the University of Oklahoma's Dodge Family College of Arts and Sciences, has been leading a proactive modeling study over the last year and a half to identify bat species that are likely to carry betacoronaviruses, including but not limited to SARS-like viruses.

What are the predictors of inpatient COVID-19 mortality rates?

A new study, conducted by a multidisciplinary team of researchers from Suffolk University, Boston, Massachusetts, examined the relationship between baseline staffing levels of registered nurses (RNs), hospitalists, emergency medicine physicians, and intensivists (staff) and hospital-level COVID-19 mortality rates. The research builds on and extends earlier research that examined a subset of hospital-level characteristics over a shorter time period.
