The Question

Are the seasonal fluoroquinolone usagepatterns related to the timing of the influenza seasons and what proportion ofuse is associated with influenza activity?

What we found

A contemporaneous relationship betweenseasonal influenza activity and antibiotic use was determined. Specifically, respiratoryfluoroquinolone increases during the same month that influenza activityincreases.

Why it matters

Fluoroquinolone cannot treat viral infections. A significant proportion of the increase ofantimicrobial usage during influenza season is probably unnecessary and probablycontributes to antimicrobial resistance.
