Abstract
The purpose of this study was to estimate the
incidence density and prevalence of dengue virus infection in
Australian travellers to Asia. We conducted a multi-centre
prospective cohort study of Australian travellers over a
32-month period. We recruited 467 travellers (=16 years of
age) from three travel clinics who intended to travel Asia, and
387 (82.9 ) of those travellers completed questionnaires and
provide samples pre- and post-travel for serological testing for
dengue virus infection. Demographic data, destination
countries and history of vaccinations and flavivirus infections
were obtained. Serological testing for dengue IgG and IgM by
enzyme-linked immunosorbent assay (ELISA) (PanBio assay)
was performed. Acute seroconversion for dengue infection
was demonstrated in 1.0 of travellers, representing an
incidence of 3.4 infections per 10,000 days of travel (95
confidence interval [CI]: 0.9?8.7). The seroprevalence of
dengue infection was 4.4 and a greater number of prior trips
to Asia was a predictor for dengue seroprevalence (p=0.019).
All travellers experienced subclinical dengue infections and
had travelled to India (n=3) and China (n=1). This
significant attack rate of dengue infection can be used to
advise prospective travellers to dengue-endemic countries.
