Dengue/DHF: an emerging disease in India

Area of Science:

• Public Health
• Infectious Diseases
• Vector-Borne Diseases

Background:

• Dengue fever and dengue hemorrhagic fever (DHF) are emergent and endemic diseases in India, characterized by periodic annual outbreaks.
• These infections cause undifferentiated fever and severe DHF, leading to widespread hospitalization, high mortality and morbidity, and significant socio-economic impact.
• Effective prevention and control strategies are essential to mitigate the public health threat posed by dengue outbreaks.

Purpose of the Study:

• To highlight the critical need for robust disease surveillance systems for timely dengue case management.
• To emphasize the importance of vector surveillance for implementing effective control measures against the Aedes aegypti mosquito.
• To underscore the urgent requirement for advanced diagnostic strategies for early dengue diagnosis.

Main Methods:

• Disease surveillance for monitoring dengue case incidence and trends.
• Vector surveillance focusing on the Aedes aegypti population.
• Review of current diagnostic approaches and their limitations.

Main Results:

• Dengue outbreaks necessitate continuous monitoring through disease surveillance.
• Vector surveillance is vital for the timely deployment of control interventions.
• Current diagnostic methods may not facilitate sufficiently early detection.

Conclusions:

• Integrated disease and vector surveillance are fundamental for managing dengue outbreaks in India.
• Early diagnosis is crucial for reducing illness duration, hospitalization, and associated complications.
• Development and implementation of effective diagnostic strategies are urgently needed.
