Background |
Dengue has emerged as the most widespread and rapidly increasing vector-borne disease in the world with the highest ever number of cases reported in 2024 [1]. Dengue is a vector-borne disease caused by one of the four serotypes of DENV. With climate change, rapid urbanization and increased movement of people and goods, there has been increase in the number of cases as well as the geographical expansion of both the virus and the primary vector, Aedes aegypti [1, 2]. Where there is presence of the vector, importation of infections from travel and other human movements can lead to autochthonous transmissions and outbreaks [3].
Over the past 30 years, the incidence, prevalence and mortality related to dengue have risen significantly, particularly in Southeast Asia and Latin America [3]. As of 2021, the global age standardized incidence rate of dengue was 752 per 100,000 population and is expected to increase to 862 per 100,000 population by 2035 [3]. The South East Asia Region which is endemic to dengue has a population of 1.3 billion people and India, Indonesia, Myanmar, Sri Lanka and Thailand are among the most highly endemic countries in the world [4].
Dengue is an acute febrile illness with majority remaining asymptomatic. Through timely case detection and guideline-driven case management, the case fatality remains low. However, dengue fever often occurs in outbreaks that overwhelm health systems and occurs in more severe forms in children and in those with comorbidities.
In Bhutan, dengue transmission is observed mainly along the districts bordering India, where the climate is subtropical. Since the detection first case of dengue in Phuntsholing, Bhutan in 2004, there have been recurrent dengue outbreaks reported from Samtse, Phuntsholing, Gelephu and Samdrup Jongkh |
Objectives |
Among cross-border migrants and local residents in high-risk border towns in Bhutan in 2025, to:
1. Assess the level of knowledge, attitude, and practices (KAP) regarding dengue fever;
2. Identify factors influencing the adoption of dengue prevention behaviours. |
Study Methods |
This will be a community-based, cross-sectional study to be conducted in 2025 in the three border towns of Phuentsholing, Gelephu and Samdrup Jongkhar. Sample size has been calculated for proportions assuming 50% have good knowledge on dengue prevention with proportionate sampling in the three municipalities. For the migrant population, a systematic random sampling will be employed. For the local residents, a stratified random sampling will be employed. A self-designed questionnaire has been developed for the purpose of this study. |
Expected outcomes and use of results |
1. Establish the level of knowledge, attitude, and practices (KAP) regarding dengue fever;
2. And Identify factors influencing the adoption of dengue prevention behaviours. |
