The new COVID-19 strain known as “Arcturus” has increased in the U.S. so much that it has been added to the CDC’s watch list. Officially labeled XBB.1.16, Arcturus is a subvariant of Omicron that was first seen in India and has been on the World Health Organization’s watchlist since the […]
Vaccines developed early in the COVID-19 pandemic continue to provide substantial protection against severe disease and death from the disease. The SARS-CoV-2 virus has mutated significantly since late 2019. But, in many cases, the immune system can recognize later variants such as Omicron. This ability comes in part from features […]
Las recomendaciones revisadas de vacunación contra la COVID-19 reflejan el impacto de las variantes circulantes de Omicron, así como la inmunidad actual de la población debida a infecciones y vacunaciones previas, según una declaración del Grupo Estratégico Consultivo de Expertos en Inmunización (SAGE), que forma parte de la Organización Mundial […]
COVID-19 remains deadlier than influenza in severe cases requiring hospitalization, a new study shows. People who were hospitalized with Omicron COVID-19 infections were 54% more likely to die, compared to people who were hospitalized with the flu, Swiss researchers found. The results of the study continue to debunk an earlier […]
The increased risk for diabetes following COVID-19 infection has persisted into the Omicron era, but vaccination against SARS-CoV-2 appears to diminish that likelihood, new data suggest. The findings, from more than 20,000 patients in the Cedars-Sinai Health System in Los Angeles, California, suggest that “continued efforts to prevent COVID-19 infection […]
As part of its ongoing work to track variants, WHO’s Technical Advisory Group on SARS-CoV-2 Virus Evolution (TAG-VE) met on the 24 October 2022 to discuss the latest evidence on the Omicron variant of concern, and how its evolution is currently unfolding, in light of high levels of population immunity […]
Unsupervised SARS-CoV-2 rapid antigen testing with three commercial kits had 70% to 81% sensitivity during the period when Omicron emerged and became predominant in the Netherlands. Rapid antigen testing for COVID-19 has largely replaced RT-PCR testing in the ambulatory setting, but accuracy data are limited. Dutch investigators performed a prospective […]
That’s according to a study in JAMA Network Open, which says 56% of people who have the Omicron variant of the coronavirus are unaware of their infection. And it has an upside and a downside, depending on how you look at it, according to Time magazine. “It’s good news, in some ways, since it underscores the […]
Los reguladores de medicamentos británicos se han convertido en los primeros en el mundo en autorizar una versión actualizada de la vacuna contra el coronavirus de Moderna que tiene como objetivo proteger contra el virus original y la variante ómicron. En un comunicado este lunes, la Agencia Reguladora de Medicamentos (EMA) y Atención […]
Omicron BA.5 is now the dominant COVID-19 variant in the United States.1Experts said that while this subvariant may be more capable of evading natural and vaccine-induced immunity, BA.5 symptoms are similar to those caused by earlier versions of Omicron. It is very hard to distinguish one variant from the other based […]
