Abstract
Purpose The purpose of this paper is to evaluate the effectiveness of the intervention program for dengue fever prevention among people in rural communities. Design/methodology/approach A quasi-experimental study was designed for two groups. The intervention group received five weeks of dengue hemorrhagic prevention program consisted of knowledge broadcast, campaign, model house contest and group education. The control group received only the usual care of health promoting hospitals. The primary expected outcomes were changes in knowledge, perceived susceptibility, perceived severity, perceived benefit, perceived barriers and preventive action from baseline data, post-intervention and three-month follow-up, along with a comparison between the two groups. The secondary expected outcomes were changes in house index (HI) from baseline to post-intervention and three-month follow-up, along with a comparison between the two groups. Findings From the total of 64 participants, 32 were randomly assigned to the control group and 32 were randomly assigned to the intervention group. There were significant differences in knowledge, perceived susceptibility, perceived severity, perceived benefit, perceived barriers, preventive action and HI in the intervention group after received the five-week intervention program and at three-month follow-up (p<0.05). Originality/value Dengue hemorrhagic prevention program based on the Health Belief Model was effective in lowering HI and improving knowledge, perceived susceptibility, perceived severity, perceived benefit, perceived barriers and preventive action among people in rural communities. The intervention program may be beneficial in primary care in such a rural community.

Research objective The purpose of this study is to examine the effectiveness of the intervention program for dengue hemorrhagic fever prevention among rural communities in Thailand based on the theory of Health belief model (HBM) (Figure 1)
There were no significant differences in general characteristics between the intervention group and control group
Summary
Dengue is a mosquito-borne disease found mainly in countries with tropical and subtropical climates. The global prevalence of dengue has grown dramatically in recent decades. One recent estimate indicates 390m dengue infections per year (95 percent credible interval of 284–528m), of which 96m (67–136m) manifest clinical symptoms[2]. An estimated 500,000 people with severe dengue require hospitalization each year and about 2.5 percent of those infected dies[1]. Dengue fever is a disease caused by the dengue virus. The main cause of dengue virus infection in human is through bites from infected female mosquitoes (Aedes aegypti)[3]. Dengue virus is a carrier disease found in all age groups[3]. The symptoms of dengue fever include high fever, chills, fatigue, rash, nausea, vomiting, headache, sore throat and pain (muscle, back, joint and abdomen areas)[4]. The most effective intervention is to prevent mosquito bites[5]
