Summary
Social support is key for dengue prevention, not demographics. Empowering community volunteers and tailored communication are vital for effective dengue control strategies.
Area of Science:
- Public Health
- Tropical Medicine
- Community Health
Background:
- Dengue is a neglected tropical disease targeted for eradication by the WHO.
- Community participation is essential for successful dengue control, requiring public engagement beyond technical solutions.
- This study investigated community needs, perceptions, and emotional drivers for dengue prevention to inform policy.
Purpose of the Study:
- To examine factors influencing dengue prevention practices in Thailand.
- To identify community needs and perceptions related to dengue control.
- To recommend tailored policies for effective dengue prevention in diverse settings.
Main Methods:
- A mixed-methods study using triangulation in four regions of Thailand (Nov 2023-Apr 2024).
- Quantitative surveys (n=664 community members, n=430 health personnel) and qualitative data (10 community FGDs, 16 health personnel FGDs, 23 IDIs).
- Logistic regression for quantitative analysis and thematic analysis for qualitative data, with integrated interpretation.
Main Results:
- Most participants actively practiced dengue prevention, with social support being a strong predictor (OR 19.81).
- Demographic factors and perceived susceptibility/severity were not significant predictors.
- Higher practice levels were seen in the northeast region and among health personnel aged ≥50; village health volunteers play a crucial role, but challenges like low risk perception and cultural barriers exist.
Conclusions:
- Effective dengue control needs context-specific strategies, community engagement, empowered village health volunteers, and enhanced vector control.
- Early warning systems and intersectoral collaboration are vital for high-risk areas.
- Culturally tailored communication can improve vaccine acceptance and support sustainable, community-centered dengue prevention.

Vasectomy is a surgical form of male sterilization that involves severing and sealing the vasa deferentia, preventing sperm from mixing with semen during ejaculation. Because a vasectomy does not impact the testes' ability to produce testosterone, hormone levels, libido, and sexual function generally remain unchanged. While vasectomy is highly effective in preventing pregnancy, with a success rate near 99.85%, rare cases of recanalization (spontaneous reconnection) can occur. Although...

Biopharmaceutical studies constitute a vital field aiming to enhance drug delivery methods and refine therapeutic approaches, drawing upon diverse interdisciplinary knowledge. In research methodologies, the choice between controlled and non-controlled studies significantly influences the study's reliability and accuracy.
Non-controlled studies, commonly employed for initial exploration, lack a control group, rendering them susceptible to biases and external influences. In contrast,...

Accurate diagnosis and effective prevention are critical in managing Acute Kidney Injury (AKI), which is linked to high mortality rates ranging from 10% to 80%. Timely recognition of at-risk patients and careful monitoring can significantly reduce the likelihood of kidney damage.Diagnostic Assessments:The diagnostic process starts with a comprehensive medical history to identify prerenal, intrarenal, and postrenal causes.Prerenal causes, such as dehydration, hypotension, or blood loss, should...

01:29Methods for Controlling Microbial Growth
1.8K
Microbial growth control refers to various methods employed to inhibit, reduce, or eliminate microorganisms to ensure safety and hygiene across different settings. These methods are categorized based on the target environment and the level of microbial control required.Biocides are versatile agents designed to control microorganisms by either inhibiting their growth or outright killing them. These agents work through various physical, chemical, mechanical, or biological mechanisms. The...

Biological agents offer an effective means of controlling microbial growth by leveraging natural processes like predation, competition, and the secretion of antimicrobial substances.Predatory bacteria such as Bdellovibrio species target and kill pathogens like Salmonella and E. coli. They are widely used in poultry farms to control infections. Myxococcus species help combat plant-pathogenic fungi. These naturally occurring predators serve as eco-friendly alternatives to chemical pesticides and...
