Had a travelling companion contract dengue fever once and I can assure you it definitely is not something you want to contract.
If you observe from the backyard, empty any standing water that may have collected in buckets, bird baths, etc.
Wear long-sleeved, light-coloured clothing, and cover your feet. Use insect repellent containing DEET (diethyl toluamide) or picaridin and reapply according to the label.
