In December 2019, China witnessed the emergence of a novel coronavirus, SARS-CoV-2. Its ability to spread quickly made it a global pandemic. The United States has been greatly affected, with more than 980,000 lives lost so far. Diagnosis is made primarily through nasopharyngeal swab for polymerase chain reaction. Point-of-care testing by antigen is less sensitive and specific and may require polymerase chain reaction confirmation. Management of the COVID-19 patient remains largely supportive. Steroids are now a therapy mainstay if the patient is hypoxic. Direct antivirals, such as nirmatrelvir/ritonavir, remdesivir, or molnupirivir, can be used if certain criteria are met. SARS-CoV-2 is transmitted primarily by inhalation of large droplets, though transmission by aerosolization may occur, particularly via certain procedures. In the hospital setting, use of personal protective equipment for the care of COVID-19 patients has largely remained the same, with full use of gowns, gloves, respirators, and eye protection. Inadequate supply at the start of the pandemic required innovative ways to reprocess and extend the use of personal protective equipment. Three vaccines are now available in the US, all with excellent efficacy against severe disease and hospitalization, though booster doses are needed to bolster waning antibody levels. The possibility of emerging variants continues to remain a threat to control of the pandemic. The leader of the World Health Organization, Dr. Tedros, has stated, “The pandemic will not be over anywhere until it’s over everywhere.”
