  1. Overall cumulative dengue incidence and incidence by age classes were compared for passive surveillance (PS) dengue illness (defined as symptoms, warning signs and laboratory confirmation) and PS possible dengue (defined as clinical symptoms only, without warning signs and without laboratory confirmation) per 10,000 residents in Machala per year. Cases included in the incidence calculations are from sentinel study sites only
