Abstract

We conducted a study in a dengue-endemic area of Colombia to evaluate the dynamics of transmission of dengue viruses during and after epidemics. Information was simultaneously gathered about occurrence of infection in humans and mosquitoes every three months in four cities with endemic transmission. Viral isolation was confirmed in 6.7% of the persons and most were asymptomatic. Adult mosquito and larvae house indexes were not found associated with increased burden of disease. The only entomologic indicator related to dengue infection in humans was the pooled infection rate of mosquitoes. infection rates showed significant differences between the epidemic (10.68, 95% confidence interval [CI] = 7.04–15.62) and after epidemic periods of the study (6.15, 95% CI = 3.46–10.19). In addition, were also infected with dengue viruses. Increases in mosquito infection rates were associated with increases in human infection rates in the following trimester.
