ICMR Study Finds All Four Dengue Virus Strains Circulating in Eight Indian States
A nationwide ICMR-backed study analyzing 6,889 dengue cases from 2023 to 2025 found that all four dengue virus serotypes (DENV-1 to DENV-4) are circulating simultaneously in eight Indian states and Union Territories, including Andhra Pradesh, Gujarat, Haryana, Madhya Pradesh, Maharashtra, Rajasthan, Tamil Nadu, and West Bengal. The study highlights dengue's hyperendemic status in these regions and notes co-infections with multiple serotypes. These findings underscore the importance of a dengue vaccine that protects against all four strains as India prepares to introduce its first indigenous vaccine.
