FIGURE 3-11 Number of cases of each clinical disease expression type and epidemic reproductive rate attributable to each of these clinical disease types for each epidemic generation. Values shown are averages from 35 epidemic simulations for the 6,000-person ring town under response scenario 3. Generation 0 = index (attack) cases. Ordinary (open bars), modified (striped bars), and hemorrhagic (closed bars) smallpox cases are shown. (A) Cases of each clinical disease type by epidemic generation. (B) Epidemic reproductive rate for each clinical disease type at each epidemic generation.
