Dengue fever is spread by mosquitoes. Find and empty all standing water places [cans, tires, bottles, trash like that, swamps, puddles, etc.] and spray insecticide all over the place.

Dear Bumblebee, There is no commercially available vaccine for the dengue flavivirus. However, one of the many ongoing vaccine development programs is the Pediatric Dengue Vaccine Initiative (PDVI [1]) which was set up in 2003 with the aim of accelerating the development and introduction of dengue vaccine(s) that are affordable and accessible in endemic countries.

Thai researchers, in phase III testing, have planned to test a dengue fever vaccine on 3,000-5,000 human volunteers within the next three years after having successfully conducted tests on animals and a small group of human volunteers.

Primary prevention of dengue mainly resides in eliminating or reducing the mosquito vector for dengue. Public spraying for mosquitoes is the most important aspect of this vector. Application of larvicides such as Abate® to standing water is more effective in the long term control of mosquitoes. Initiatives to eradicate pools of standing water (such as in flowerpots) have proven useful in controlling mosquito borne diseases. Promising new techniques have been recently reported from Oxford University on rendering the Aedes mosquito pest sterile.

Personal prevention consists of the use of mosquito nets, repellents, cover exposed skin, use DEET-impregnated bednets, and avoiding endemic areas. This is also important for malaria prevention.
