Relationship between Transmission Intensity and Incidence of Dengue Hemorrhagic Fever in Thailand
Figure 7
Age-specific relationship between DHF incidence and transmission intensity predicted by simulations.
Age-stratified incidence of DHF in the last three years from each simulation were averaged. The parameters inputted to simulations were: two-year cross-immunity (A–D); age-dependency which assumes a higher probability of manifesting DHF in older individuals (E–H); control scenario without cross-immunity or age-dependency (I–L). DHF incidence presented for the entire population (A, E, I) or stratified into 0–4 years (B, F, J), 5–24 years (C, G, K), and ≥25 years (D, H, L). Y-axis is log scale.
