: Dengue has not reached an endemic status in Taiwan; nevertheless, we have implemented a fever
screening program at airports for the early detection of febrile passengers with a : A moderate sensitivity of detecting dengue at the airports examined in this study indicated some
limitations of the fever screening program for the prevention of importation. The screening program could assist in
the rapid triage for self-quarantine of some symptomatic dengue cases that were in the viremic stage at the
borders and contribute to active sentinel surveillance; however, the blocking of viral transmission to susceptible
populations (neighbors or family) from all of the viremic travelers, including those with or without symptoms, is
critical to prevent dengue epidemics. Therefore, the reinforcement of mosquito bite prevention and household
vector control in dengue-endemic or dengue-competent hotspots during an epidemic season is essential and
highly recommended.
