Severe COVID-19 is a medical emergency and requires immediate hospitalization.

1. Severe dyspnea

2. Hypoxia

3. Serious dehydration

4. P/F ration < 300

5. New bilateral infiltrated on imaging

6. Altered level of consciousness (e.g., confusion, delirium, lethargy)*

*If this symptom is present, emergency medical attention should be sought right away, even if other symptoms are absent. Often times, this is the only severe symptom and can be present even when other "classic" COVID symptoms are absent. Even if this doesn't indicate COVID infection, it should still be treated as a medical emergency.
