AbstractNew COVID-19 variants of concern continue to develop. Incubation period, transmissibility, immune escape, and treatment effectiveness differ by variants of concern. Physicians should be aware that the characteristics of the predominant variants of concern determine aspects of diagnosis and treatment. Multiple testing modalities exist; the most appropriate testing strategy varies depending on the clinical scenario, with factors of test sensitivity, turnaround time, and the expertise required for specimen collection. Three types of vaccines are available in the United States, and all people six months and older should be encouraged to receive one because vaccination is effective in reducing the incidence of and hospitalizations and deaths associated with COVID-19. Vaccination may also reduce the incidence of post-acute sequelae of SARS-CoV-2 infection (i.e., long COVID). Consider medications, such as nirmatrelvir/ritonavir, as first-line treatment for eligible patients diagnosed with COVID-19 unless logistical or supply constraints occur. National Institutes of Health guidelines and local health care partner resources can be used to determine eligibility. Long-term health effects of having COVID-19 are under investigation.
