Evaluation and management of Covid-19 depend on the severity of the disease. Patients with mild disease usually recover at home, whereas patients with moderate disease should be monitored closely and sometimes hospitalized.
Characteristics and Management of Covid-19 According to Disease Severity
|Asymptomatic or Presymptomatic||Positive SARS-CoV-2 test; no symptoms||Monitoring for symptoms|
|Mild Illness||Mild symptoms (e.g., fever, cough, or change in taste or smell); no dyspnea||Clinical monitoring and supportive care|
|Moderate Illness||Clinical or radiographic evidence of lower respiratory tract disease; oxygen saturation ≥94%||Clinical monitoring; if patient is hospitalized
and at high risk for deterioration, possibly remdesivir
|Severe Illness||Oxygen saturation <94%; respiratory rate ≥30 breaths/min; lung infiltrates >50%||Hospitalization, oxygen therapy, and specific
therapy (remdesivir, dexamethasone)
|Critical Illness||Respiratory failure, shock, and multiorgan dysfunction or failure||Critical care and specific therapy (dexamethasone, possibly remdesivir)|
