Cureus 2022 Apr 28;14(4):e24563. Epub 2022 Apr 28.

Internal Medicine, Oak Hill, Tampa, USA.

Background and objective The severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) is a novel coronavirus that causes coronavirus disease 2019 (COVID-19) infection, with symptoms ranging from mild upper respiratory illness to multisystem organ failure, and even death.
