Review Confirms Reduced Seriousness of Omicron SARS-CoV-2 Variant of Concern
I n a recent study, researchers review existing literature to quantify the transmissibility, immune evasion, reinfection, and severity of the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) Omicron variant. As a result of its high transmissibility, the SARS-CoV-2 Omicron variant is rapidly spreading across the world. In the United States, for example, this strain of SARS-CoV-2 is responsible for 95% of all new coronavirus disease 2019 (COVID-19) cases since January 1, 2022. Extensive research is needed to understand the extent to which the increased transmissibility and virulence of Omicron threaten public health globally. Furthermore, it is also crucial to determine how the global population should recognize these dynamics, perceive risk, and adhere to public health and social measures amid the emergence of the Omicron variant. Study In the present study, the researchers performed a literature search in PubMed , Web of Science, Scopus, ScienceDirect, Google Schol
