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 o 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.

To evaluate the effect of a health education program on the prevention and control of dengue hemorrhagic fever (DHF) in the municipality of Mae Sot, Tak Province, a survey of adult residents, mainly housewives, was conducted in late April 1990 to assess their knowledge of DHF and practice of preventive methods. A total of 417 respondents from 417 households selected by a systematic-cluster sampling method were interviewed. More than 90% of them knew that the disease is transmitted by Aedes mosquitos and indicated water jars and water retention in the houses as the common breeding places. However, the other two common breeding places, ant-traps and cement baths, were less frequently mentioned. This finding was consistent with the greater proportion of respondents who reported no larval control methods for these two kinds of containers than for the others. Covering water containers was the most common practice to prevent mosquito breeding in drinking-water containers whereas addition ...

Background: The current study assessed the knowledge, attitudes, and practices (KAP) of at-risk populations for malaria and/or dengue fever in relation to mosquito exposure and household mosquito control practices. Specific objectives included comparison of individual and household level health practices between a rural and urban setting in Thailand. Findings are intended to guide Thailand Ministry of Health educational campaigns targeting arthropod-borne disease. Methods: A mixed method design was employed using a forced choice and open-ended questionnaire to assess KAP of participants seeking point-of-care treatment for malaria and/or dengue fever at government health-care facilities. Following informed consent, household construction characterization (percent eave gap, floor, wall, and roof material) and mosquito collections both indoors (using aspiration) and outside (using traps) were conducted at a subsample of participant homes. All mosquitoes were identified to genus and anopheline and aedine samples processed for potential pathogen infection. Results: A total of 64 participants were recruited from both study sites; 62 categorized as malaria symptomology and 2 categorized as dengue across all study healthcare facilities. Significant associations between study site and household construction were indicated. Trends also identified household level practices and both occupation and household construction regarding type of mosquito control products purchased and the abundance of mosquitoes in sampled homes.
One of the strategies to control dengue in Indonesia is changing behaviour practice using slogan 3M plus. 3M is consisted of cleaning water container, covering water container, and burying or throwing discarded items. Plus is activity to avoid mosquito bite (using repellent or long sleeves) and activity to reduce mosquito breeding place such as fogging. This study aimed to determine level of knowledge, perception, and prevention behaviour regarding dengue in Lowokwaru sub district, urban area in Malang, Indonesia. Cross sectional study using semi-structured questionnaire among 220 respondents was conducted by face-to-face interview. More than 43 percent (43.6%) of respondents exhibited moderate level of knowledge. They had good knowledge regarding cause and severity of dengue. However, they had low knowledge about prevention actions. Most of the respondents had positive perception towards dengue. Positive perception was found towards susceptibility and severity of dengue and only moderate perception towards prevention actions. Most of them (61%) were more likely to perform 3M prevention behavior than plus prevention behavior. Respondents had low knowledge and need improvement level of practice regarding prevention actions particularly plus prevention activities. Therefore, this study suggests that 3M plus campaign should provide more information about prevention behaviour knowledge in terms of plus activities.

To study the factors associated with dengue prevention and control in Moo 6 (the 6th village) and Moo 7 of Tambon Kaeng-phak-kut, Thaluang District, Lopburi Province. The authors reviewed the raw data collected by public health officers and village health volunteers (VHVs) as their routine tasks. The authors analyzed the data, 30 dwellings per each village, to compare the demographics, knowledge, attitude, and practice of subjects from Moo 6, a dengue-outbreak community, with that from Moo 7, a control group, as well as larval indices between these 2 studied groups. The present retrospective study is approved by Siriraj Institutional Review Board, Certificate of Approval No. Si393/2012. Both groups of subjects had no statistically significant difference in basic dengue knowledge (p = 0.862), attitude towards dengue prevention and control, practical knowledge (p = 0.457), and actual practice to eliminate Aedes larvae and prevent it laying eggs, except for the practice of managing wat...
Introduction: Dengue is the most prevalent infectious mosquito-borne viral infection in the world. Over time dengue has caused high mortality and morbidity. Methods: A cross-sectional study was conducted to assess the level of knowledge, attitude, and practice among 510 residents of Ja-Ela MOH area using an interviewer-administered questionnaire. Ethical clearance was obtained from the National Institute of Health Science Kalutara. Results: The majority (50.8%) of the respondents were females, and the mean age of the sample was 43.7±16.7 years. The study results showed that 56.5% (n = 288), 52.9% (n = 270), and 50.7% (n = 257) of the sample had good knowledge, attitudes, and practices (KAP) towards dengue prevention, respectively. Good knowledge is significantly associated with 41-60 years of age (odds ratio [OR] = 2.513, P < 0.001), secondary education or higher (OR = 1.857, P = 0.008), and a monthly income of LKR 20 000-40 000 and more than 40 000 (OR = 0.477, P = 0.016; OR = 0.440, P = 0.015). Non-Sinhalese nationality (OR = 0.180, P = 0.033) was associated with poor levels of knowledge. Good attitudes towards the prevention of dengue were found in males (OR = 2.095, P = 0.001), unemployed individuals (OR = 1.759, P = 0.018), and individuals with a monthly income of < LKR 20000 (OR = 2.393, P = 0.001). Poor practices towards dengue prevention were found in other nationalities compared to Sinhalese (OR = 0.104, P = 0.001) while Roman Catholics had poor practices towards dengue prevention (OR = 0.677, P = 0.041). The study shows that the experience of dengue is positively associated with better attitudes towards dengue prevention (Mann-Whitney U test; P < 0.001). Conclusion: KAPs were not significantly correlated with each other. Targeted health education and promotion programmes provided for specific populations should be considered a priority activity.

Dengue hemorrhagic fever (DHF), a disease transmitted by Aedes mosquitos, remains a serious public health problem in Thailand. This paper describes the effect of health education efforts on a community-based DHF vector control program in the municipality of Mae Sot District, Tak Province, northern Thailand, from 1988 through 1990. In 1988, public health education on DHF and larval control through mass media, lectures and discussions reduced the Aedes Breteau index from 241 in March to 126 in June 1988. In 1989 and 1990, twice a year house-to-house visits by trained health workers were added to the health education campaigns. Aedes larval indices were decreased far more in the epidemic year of 1990 than in 1989. During this 3-year period, water-storage containers for drinking, washing, bathing and ant-traps were the primary sources of larval habitats, accounting for about 90% of the total breeding places. Reduction of Aedes larvae in these sources was due to various larval control me...

Mosquito borne diseases are endemic in most part of the country. While public health efforts are placed towards the elimination of major vector borne diseases like malaria and filariasis, climatic and manmade environmental changes has led to threats of reemergence of mosquito borne diseases like dengue and chikungunya in new regions. There are needs of studies among community people regarding knowledge and perception of vector borne diseases to change the attitudes of people towards vector control and avoid risky behavior by application of behavior change communication tools.

Background: Dengue prevention is important for controlling the spread of dengue infection. Transmission of dengue can be prevented by controlling mosquito breeding sites. Indonesia has dengue a prevention program to minimize mosquito breeding sites known as 3 M Plus. This study aimed to investigate factors associated with dengue prevention behaviour among respondents in the Lowokwaru subdistrict, an urban area in Malang, Indonesia. Methods: This cross-sectional study used a semi-structured questionnaire that was conducted by face-to-face interview. Results: Older respondents (> 60 years and 41-60 years) showed better dengue prevention behaviour than younger respondents (21-40 years and < 21 years) (p value = 0.01). Proportionally more male respondents showed poor dengue prevention behaviour compared with female respondents (p value = 0.007). Respondents who lived in Malang for long durations showed better dengue prevention behaviour compared with those who lived there for a shorter period (p value = 0.016). Those with more family members in their households practiced better dengue prevention behaviour compared with those with fewer family members (p value = 0.004). Perception was associated with dengue prevention behaviour. Respondents who had higher perceived susceptibility showed better dengue prevention behaviour compared with those who had moderate perceptions (p value = 0.000). Conclusions: Age, gender, duration of stay in Malang, number of family members, and perception of dengue susceptibility were associated with dengue prevention behaviour.

Due to the absence of dengue vaccination, vector control is the only measure to prevent dengue outbreaks. The key element of dengue prevention is to eliminate vector habitats. Clean household environment, preventive behaviors of household members and community participation in dengue prevention and control are key successful elements. This study aimed to investigate the associations between environmental factors, dengue knowledge, perception and preventive behaviors of household and collaboration of community members and household risk of dengue by using mixed methods. One dengue epidemic province was selected from each region of Thailand including Bangkok. Two districts, one from the highest and another from the lowest dengue incidence areas, were selected from those provinces. The household leaders, community members, and local authorities in highest dengue incidence areas were interviewed by using questionnaire and through group interviews. The environment of each selected househ...
