Comparing the proportion of patients with acute respiratory infection presenting ≤2 days since illness onset who received an antiviral prescription during the 2011–2012 and 2012–2013 influenza seasons, US Influenza Vaccine Effectiveness Network. Includes 3 study sites (A, B, and D). 2011–2012 season: n = 1201; 2012–2013 season: n = 1404. *All higher risk includes those <2 or ≥65 years of age or who meet 1 or more of the other risk criteria, which puts them at higher risk for influenza complications [7]. **Other risk criteria include American Indian/Alaska Native/Pacific Islander, pregnant, or having a chronic underlying medical condition, which includes morbid obesity (body mass index ≥40 kg/m²).
