Self-reported travel histories were used in a case-control study to determine whether movement of local residents to neighboring endemic areas was a risk factor for malaria in the town of Quibdo, Colombia. Multivariate analyses showed that among residents of Quibdo, traveling to an endemic area 8–14 days before disease onset was the strongest risk factor for both (adjusted odds ratio [OR] = 28.96, 95% confidence interval [CI] = 13.9–60.32) and (adjusted OR = 14.24, 95% CI = 5.27–38.46) malaria. For individuals who did not travel outside Quibdo during the 8–14 days before disease onset, but who reported traveling 1–7, 15–21, or 22–30 days before disease onset also had an increased risk of malaria. Conversely, use of protection against mosquitoes was negatively associated with . These results highlight the need for malaria control measures that target mobile populations. A definition of imported malaria that allows distinction of imported from autochthonous cases in Quibdo town is proposed.
