A Comparative Study On Active And Passive Epidemiological Surveillance For Dengue In Five Countries Of Latin America


This study reveals the extent of under-reporting for dengue by comparing the incidence of dengue in a cohort sutdy in Latin America was compared with those reported to national epidemiological surveillance systems (NESSs). The results showed that “the incidence of confirmed dengue was 10.0-fold higher in the study than that reported to NESSs in the same localities…” demonstrating that “there is a substantial under-reporting of dengue in the NESSs. Understanding the level of under-reporting would allow more accurate estimates of the dengue burden in Latin America.”
