[2025-10-01T11:25:11.840535] [PI reasoning] **Analyzing influenza statements**

I need to identify the incorrect statement about influenza. Analyzing each option: 

For Option A, claiming a secondary attack rate of 5-15% seems accurate, as it falls within the expected range. Option B mentions that virus shedding can happen about a day before symptoms appear, which is true. For Option C, stating that children aged 1-5 are not a high-risk group is inaccurate since the CDC considers those under 5, especially under 2, a high-risk group. Therefore, Option C is the false statement.
