Core Tip
Core Tip: Since March 2022, the Omicron wave has affected Shanghai, China. Many elderly patients with severe and nonsevere Omicron severe acute respiratory syndrome coronavirus 2 variant infections have been admitted to our hospital. These patients have a precise diagnosis, complete examination, and clear treatment results. After China adjusts its coronavirus prevention and control policies in 2023, findings such as those in this article will no longer be available.
