Dengue: knowledge gaps, unmet needs, and research priorities

Area of Science:

• * Medical Entomology and Tropical Infectious Diseases
• * Public Health and Epidemiology
• * Vaccinology and Immunology

Background:

• * Dengue virus, a mosquito-borne pathogen, causes approximately 100 million annual cases, creating substantial public health, social, and economic burdens, particularly in low- and middle-income countries.
• * Significant research advancements are providing new insights and enabling innovative interventions for dengue prevention and control.
• * Existing knowledge gaps persist in basic dengue understanding and the development of effective control tools.

Purpose of the Study:

• * To review current strategies for dengue diagnostics, prognosis, surveillance, and vector control in resource-limited settings.
• * To discuss the potential impacts of dengue vaccine introduction.
• * To synthesize current knowledge and recent findings on dengue epidemiology, immunology, and pathogenesis.

Main Methods:

• * Comprehensive literature review of recent dengue research.
• * Analysis of existing diagnostic, prognostic, and surveillance approaches.
• * Evaluation of vector control strategies and vaccine development progress.

Main Results:

• * Advances in understanding dengue epidemiology, immunology, and pathogenesis are crucial for natural infection and vaccine efficacy.
• * Current diagnostics, prognostics, and surveillance methods require ongoing refinement for optimal public health impact.
• * Vector control remains a critical component of dengue management, alongside emerging vaccine candidates.

Conclusions:

• * Integrated approaches combining diagnostics, surveillance, vector control, and vaccination are essential for effective dengue management.
• * Further research is needed to address knowledge gaps and optimize interventions, especially in endemic regions.
• * Understanding dengue's complex epidemiology and immunology is key to developing and deploying successful vaccines and control strategies.
