Brief summary

The project will use both a randomised control trial and prospective cohort design. Participants will be Western Australian travellers planning to depart for Bali. Half of participants will be randomly allocated into an intervention group and receive prepared online travel health information. After returning from Bali, both the intervention and non-intervention group will be invited to complete an online survey with questions concerning any communicable disease symptoms and health impacts.

Interventions

The intervention will be a short (~two minute) animated video containing health information specific to Bali/Southeast Asia. Potential areas of interest will include; foodborne illness (e.g. ‘bali belly), mosquito borne illness (e.g. dengue, chikungunya), rabies (avoiding monkey and canine contacts), and measles (checking vaccination status). This video will be complemented by written information below the video. A link to this video will be emailed out in the intervention participants, and w

This video will be complemented by written information below the video. A link to this video will be emailed out in the intervention participants, and will be viewed no less than one month before the participant departs for Bali. This is to allow the participant sufficient time to check vaccinations ect. The adherance will be monitored by a video heatmap: a graphical representation of a single viewing session. For each viewer it will show the specific interaction the viewer had, including when/where was it watched, which portion was skipped and which portion was watched again. Next to each heatmap the percentage of the video that viewers have watched will be displayed.
