Summary
Dengue fever incidence significantly increased in Southeast Asia, with a notable dip during the COVID-19 pandemic. Sustained surveillance and control strategies are crucial for managing this persistent public health threat.
Area of Science:
- Epidemiology
- Public Health
- Vector-Borne Diseases
Background:
- Dengue fever is a major vector-borne disease in Southeast Asia, straining public health resources.
- Climate change and travel may increase dengue prevalence.
- The COVID-19 pandemic might have altered dengue's epidemiological patterns.
Purpose of the Study:
- To evaluate changes in dengue incidence epidemiology in Southeast Asia.
- To analyze long-term trends in dengue cases across multiple countries.
Main Methods:
- A retrospective, multicountry ecological study was conducted.
- Data from 7 Southeast Asian countries (2000-2023) were analyzed.
- Linear trends in annual dengue incidence rates were calculated.
Main Results:
- Significant increasing trends in dengue incidence were observed in Singapore, Vietnam, Malaysia, and the Philippines.
- A temporary decrease in dengue cases coincided with the COVID-19 pandemic.
- Analysis included data from Thailand, Singapore, Vietnam, Malaysia, the Philippines, Cambodia, and Taiwan.
Conclusions:
- Dengue remains a significant public health challenge in Southeast Asia.
- Despite a pandemic-related decline, dengue cases have resurged, highlighting its persistent threat.
- Enhanced surveillance and innovative control strategies are essential for dengue mitigation.

01:26Introduction to Epidemiology
1.7K
Epidemiology, known as the cornerstone of public health, involves studying the distribution and determinants of health-related events in defined populations and applying these insights to control health issues. This is essential for understanding how diseases spread, identifying populations at greater risk, and implementing measures to control or prevent outbreaks. Epidemiology addresses not only infectious diseases but also non-communicable conditions like cancer and cardiovascular disease,...

Disease surveillance is the systematic collection, analysis, and interpretation of health data essential to the planning, implementation, and evaluation of public health practice. This process integrates data dissemination to entities responsible for preventing and controlling disease, injury, and disability. Surveillance systems provide crucial information for action, helping public health authorities make informed decisions to manage and prevent outbreaks, ensure public safety, optimize...

1.3K
Biases can arise at various stages of research, from study design and data collection to analysis and interpretation. Recognizing and addressing these biases is essential to ensure the validity and reliability of epidemiological findings.Broadly speaking, biases in epidemiology fall into three main categories: selection bias, information bias, and confounding. A more detailed description of possible biases is:
