Abstract
Background
The upsurge in the dengue cases presents significant challenge to the public health systems, with an estimated 390 million infections yearly. This study examines the trends and patterns in dengue incidence and mortality in India in the period 1990-2019.
Methods
Information regarding the incidence and mortality rates of dengue from 1990-2019 was obtained from the Global Burden of Disease Study 2019. The analysis of changes across time and place was done using a geographic map of age-standardized rates. Joinpoint regression analysis was used to identify key periods of change.
Results
The study found that India's age-standardized incidence rate (ASIR) of dengue shows a modest Average Annual Percent Change (AAPC) of 0.14% (95% CI: 0.12 to 0.15), lower than global and South Asian rates. The age-standardized death rate (ASDR) in India is decreasing, with an AAPC of -0.80% (95% CI: 0.69 to 0.89), contrasting with the increasing trend in South Asia. Regional disparities within India were evident with states like Delhi, Jharkhand and Tripura experiencing a decline in incidence, while states such as Assam, Goa, and Odisha showed an increase in mortality rates.
Conclusion
Despite a modest increase in incidence, India has achieved a reduction in mortality rates, indicating progress in dengue control. However, the persistence of regional disparities highlights the need for tailored public health strategies. This study emphasizes the importance of continuous monitoring, region-specific interventions, and alignment with the Sustainable Development Goals, to effectively combat dengue in India and contribute to global dengue control efforts.
