- Are hospitalized due to COVID-19, or
- Require oxygen therapy due to COVID-19, or
- Require an increase in baseline oxygen flow rate due to COVID-19 in those on chronic oxygen therapy due to underlying non-COVID-19–related comorbidity
- On July 30, 2021, the EUA was extended to include the use of casirivimab/imdevimab for post-exposure prophylaxis.
