In Medical Laboratories Across The US The Omicron Variant Is Deepening Severe Staffing Shortages

Medical laboratory professionals form the backbone of health care and the public health system. They conduct some 13 billion laboratory medicine tests annually in the U.S. As of January 2022, these individuals had also performed more than 860 million COVID-19 tests and counting during the pandemic. Why should anyone care? Laboratory testing is the single highest-volume medical activity affecting Americans, and it drives about two-thirds of all medical decisions made by doctors and other health care professionals. Simply put, every time you enter a hospital or health care facility for care, your life is in the hands of a medical laboratory professional. Like other health care and health professionals, these lab workers are experiencing dangerously low staffing numbers as a result of the p...

Here’s What Scientists Are Doing Right Now To Understand The New Coronavirus Omicron Variant

Scientists around the world have been racing to learn more about the new omicron strain of SARS-CoV-2, first declared a “variant of concern” on Nov. 26, 2021 by the World Health Organization. Officials cautioned that it would take several weeks before they’d know whether the recently emerged coronavirus variant is more contagious and causes more or less serious COVID-19 than delta and other earlier variants, and whether current vaccines can ward it off. Peter Kasson is a virologist and biophysicist at the University of Virginia who studies how viruses such as SARS-CoV-2 enter cells and what can be done to stop them. Here he explains what lab-based scientists are doing to help answer the outstanding questions about omicron. Does prior immunity protect against omicron? These are the key lab...

What Researchers Know And What They Don’t Know About The New Coronavirus Variant – Will Omicron Be More Contagious Than Delta? A Virus Evolution Expert Explains

Suresh V. Kuchipudi, Penn State A new variant named omicron (B.1.1.529) was reported by researchers in South Africa on Nov. 24, 2021, and designated a “variant of concern” by the World Health Organization two days later. Omicron is very unusual in that it is by far the most heavily mutated variant yet of SARS-CoV-2, the virus that causes COVID-19. The omicron variant has 50 mutations overall, with 32 mutations on the spike protein alone. The spike protein – which forms protruding knobs on the outside of the SARS-CoV-2 virus – helps the virus adhere to cells so that it can gain entry. It is also the protein that all three vaccines currently available in the U.S. use to induce protective antibodies. For comparison, the delta variant has nine mutations. The larger number of mutations in the...
