Figure 3

Rate of hospital admission (A) and pneumonia (B) per 100 pandemic influenza A (H1N1)-confirmed cases. Results for both male and female are shown separately for those aged < 50 years old and those aged ≥ 50 years old. Comparisons were made of the rate of hospital admission (*P < 0.001) and pneumonia (P = 0.0019) between male and female aged ≥ 50. There was a significant difference of the rate of admission between aged < 50 years old and aged ≥ 50 years old in both sexes (P < 0.001).
