Will The New COVID-19 Variant BA.2, Cause Another Wave Of Infections In The US?

A new omicron subvariant of the virus that causes COVID-19, BA.2, is quickly becoming the predominant source of infections amid rising cases around the world. Immunologists Prakash Nagarkatti and Mitzi Nagarkatti of the University of South Carolina explain what makes it different from previous variants, whether there will be another surge in the U.S. and how best to protect yourself. What is BA.2, and how is it related to omicron? BA.2 is the latest subvariant of omicron, the dominant strain of the SARS-CoV-2 virus that causes COVID-19. While the origin of BA.2 is still unclear, it has quickly become the dominant strain in many countries, including India, Denmark and South Africa. It is continuing to spread in Europe, Asia and many parts of the world. The omicron variant, officially known...

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...

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...

With A New Fast-Spreading Coronavirus Variant On The Loose – How To Stay Safe

A fast-spreading variant of the coronavirus that causes COVID-19 has been found in at least 10 states, and people are wondering: How do I protect myself now? We saw what the new variant, known as B.1.1.7, can do as it spread quickly through southeastern England in December, causing case numbers to spike and triggering stricter lockdown measures. The new variant has been estimated to be 50% more easily transmitted than common variants, though it appears to affect people’s health in the same way. The increased transmissibility is believed to arise from a change in the virus’s spike protein that can allow the virus to more easily enter cells. These and other studies on the new variant were released before peer review to share their findings quickly. Additionally, there is some evidence tha...
