The Flu by the Numbers (or When to Give Antivirals)
Seasonal influenza is typically a self-limited disease for those with normal immune systems. Supported by the Centers for Disease Control and Prevention, the 2018 Infectious Diseases Society of America guidelines recommend antiviral therapy for higher risk patients, such as those younger than 2 and older than 65, independent of symptom onset. (Clin Infect Dis. 2019;68:e1; http://bit.ly/36EsqGJ.)
They also recommend considering antivirals if symptom duration has been more than two days. Other recommendations for treatment include:
- Anyone who is hospitalized, regardless of age
- Outpatients with severe or progressive illness
- Outpatients at high risk from complications (i.e., immunocompromised)
- Pregnant women and those within two weeks post-partum
