It is caused by four different viruses and spread by Aedes mosquitoes. There are currently no vaccines. The best method of prevention is to avoid mosquito bites.

The independent variables were intention, self-efficacy, perceived seriousness, attitude, and education. The data were collected by questionnaire and analyzed by path analysis.

Results: Dengue fever preventive practice was directly and positively affected by intention (b= 0.62; 95% CI= 0.45 to 0.79; p<0.001), self-efficacy (b= 0.13; 95% CI= 0.01 to 0.25; p= 0.043), and perceived seriousness (b= 0.31; 95% CI= -0.05 to 0.67; p= 0.091). Dengue fever preventive practice was indirectly affected by attitude and education.
