Dengue in the health transition

Area of Science:

• Public Health
• Epidemiology
• Demography

Background:

• The health transition in Asia involves declining infectious diseases and infant mortality, leading to an aging population.
• This demographic shift results in a rise of adult diseases like heart disease, cancer, and diabetes.
• Increased life expectancy and healthcare costs are significant consequences of this transition.

Purpose of the Study:

• To highlight dengue as a unique vector-borne disease bridging the health transition in tropical Asian countries.
• To examine the factors contributing to the increasing prevalence and severity of dengue.
• To emphasize the need for effective Aedes aegypti control measures.

Main Methods:

• The study analyzes epidemiological trends and demographic shifts in Asian countries.
• It reviews the impact of urbanization and affluence on Aedes aegypti breeding sites.
• The abstract discusses the evolving nature of dengue virus and disease severity.

Main Results:

• Declining infant mortality and fertility rates are reshaping Asian population structures.
• Adult-onset diseases are becoming predominant health concerns.
• Dengue is identified as a growing threat, exacerbated by urban development and reduced mosquito control compliance.

Conclusions:

• Modern Asian societies face a dual burden of chronic adult diseases and persistent infectious diseases like dengue.
• Effective dengue control necessitates comprehensive strategies, including source reduction and community engagement.
• New stakeholders, including municipalities and the private sector, must play a role in managing Aedes aegypti populations.
