India's first dengue virus mapping shows all four serotypes (DENV-1, DENV-2, DENV-3, DENV-4) circulating simultaneously in eight states and Union Territories. DENV-2 was found to be the dominant strain. This finding could influence the country's upcoming dengue vaccine strategy as concurrent infections with multiple strains are linked to more severe dengue disease. Continuous molecular surveillance is essential for monitoring virus circulation and guiding policy.
