Exploring community needs in combating aedes mosquitoes and dengue fever: a study with urban community in the recurrent hotspot area.

BACKGROUND: Aedes mosquitoes are the main vector of dengue infection, a global health threat affecting millions of people annually. Conventional prevention and control methods against dengue outbreaks have only achieved marginal success. Recognizing the complex issue at hand, a multilevel participatory approach is crucial. Thus, alternative strategies that involve community engagement are increasingly being considered and attempted. While community-based vector control programs have been conducted, sustaining behavioral changes among the population remains a challenge. This study aimed to identify the specific community needs in combating Aedes mosquitoes and dengue fever as a basis to guide the development of community-driven initiatives and foster a deeper sense of ownership in the fight against dengue. METHODS: Between 1 August 2022 and 30 November 2022, we conducted a study in Hulu Langat district, Selangor, using a mixed-method design. All participants consented to the study, which comprised 27 participants (FGDs) and 15 participants (IDIs). The IDIs included two participants with a history of dengue fever, one community leader, one faith leader, seven local authorities, and four district health officers. Semi-structured interviews and discussions were performed among stakeholders and community members recruited via purposive and snowball sampling techniques. All interviews were audio-recorded before being analyzed using reflexive thematic analysis. RESULTS: These results derived from qualitative data explored the perspectives and needs of communities in combating Aedes mosquitoes and dengue fever. Interviews were conducted with various stakeholders, including community members, leaders, and health officers. The study identified the necessity of decisive actions by authorities to address the impact of the dengue epidemic, the importance of community engagement through partnerships and participatory approaches, the potential benefits of incentives and rewards to enhance community participation, and the need for sustained community engagement and education, especially via the involvement of young people in prevention efforts. These findings provide valuable insights into the design of effective strategies against Aedes mosquitoes and dengue fever. CONCLUSIONS: In short, there is an urgent need for a comprehensive approach involving multiple stakeholders in the fight against Aedes mosquitoes and dengue fever. The approach should incorporate efforts to raise awareness, provide practical resources, and foster community responsibility. The active involvement of teenagers as volunteers can contribute to long-term prevention efforts. Collaboration, resource allocation, and community engagement are crucial for effective dengue control and a healthier environment.

Association between Urinary Aflatoxin (AFM1) and Dietary Intake among Adults in Hulu Langat District, Selangor, Malaysia.

Aflatoxin is a food contaminant and its exposure through the diet is frequent and ubiquitous. A long-term dietary aflatoxin exposure has been linked to the development of liver cancer in populations with high prevalence of aflatoxin contamination in foods. Therefore, this study was conducted to identify the association between urinary aflatoxin M1 (AFM1), a biomarker of aflatoxin exposure, with the dietary intake among adults in Hulu Langat district, Selangor, Malaysia. Certain food products have higher potential for aflatoxin contamination and these were listed in a Food Frequency Questionnaire, which was given to all study participants. This allowed us to record consumption rates for each food product listed. Concomitantly, urine samples were collected, from adults in selected areas in Hulu Langat district, for the measurement of AFM1 levels using an ELISA kit. Of the 444 urine samples collected and tested, 199 were positive for AFM1, with 37 of them exceeding the limit of detection (LOD) of 0.64 ng/mL. Cereal products showed the highest consumption level among all food groups, with an average intake of 512.54 g per day. Chi-square analysis showed that consumption of eggs (X² = 4.77, p = 0.03) and dairy products (X² = 19.36, p < 0.01) had significant associations with urinary AFM1 but both food groups were having a phi and Cramer's V value that less than 0.3, which indicated that the association between these food groups' consumption and AFM1 level in urine was weak.

Prevalence and predictors of pediculosis capitis among primary school children in Hulu Langat, Selangor

Introduction: Pediculosis capitis infestation is endemic in both developing and developed countries leading to various physical, economical and psychological consequences. Our main objective was to determine the prevalence and predictors of pediculosis capitis among primary school children in Hulu Langat District, Malaysia. Methods: An analytic cross-sectional study using cluster random sampling method was carried out in Hulu Langat District, Malaysia. Self-administered pretested questionnaires were used to collect the data. Hair and scalp examination was also carried out. Multivariate logistic regression was used to control for potential confounding and determine the predictors. Results: The overall mean age of the 1,336 respondents was 9.3 years. Majority were males (52.8%), Malays (79.5%) and 81.3% of the fathers had secondary or tertiary education as compared to 77.3% for the mothers. The overall prevalence of pediculosis capitis was 15.3%. The prevalence of pediculosis was significantly higher among females (28.4%) than males (3.7%, p=0.001). Multivariate logistic regression analysis showed that age 10 years or more (Odds Ratio (OR) = 2.34, 95% Confidence Interval (CI) = 1.673 to 3.272), female gender (OR = 10.26, 95% CI = 6.620 to 15.903), history of contact with an infested person (OR = 2.11, 95% CI = 1.506 to 2.960), Indian compared to Chinese (OR = 3.55, 95% CI = 1.282 to 9.860), Malay to Chinese (OR = 2.59, 95% CI = .994 to 6.774) were associated with pediculosis capitis. Conclusions: Prevalence of pediculosis capitis among children aged 7 - 12 years in Hulu Langat District was high. There is a need for screening and treatment of pediculosis capitis in primary schools.
