Does the lack of flu in the summer mean there isn't any summer infection or is it because it's milder and not noticed in the summer? No flu infections in the summer. Nobody really understands the reason for this. Many respiratory diseases have seasonality. Allergy has an obvious rationale, but the others are much less clear. For example asthma is strongly seasonal - I follow Sepracor very closely, and it's Xopenex (a form of albuterol) sales have a very strong seasonality, with the trough typically around now and the peak in January/February. (Actually this year the trough was earlier this month - early by a few weeks). Someplace earlier in this thread I posted some seasonality articles - I'll see if I can locate them again. Peter
