The rise in dengue cases poses significant risks to public health, particularly in tropical regions like India. Severe dengue infections often require hospitalisation and can lead to increased healthcare costs and strain on medical infrastructure. The disease is primarily transmitted by Aedes aegypti mosquitoes, which thrive in areas with poor sanitation and stagnant water. The approval of Qdenga offers a new preventive measure, but challenges such as vaccine affordability, cold-chain logistics, and equitable distribution remain. Additionally, the effectiveness of mosquito-control technologies like Wolbachia-infected mosquitoes varies by location, requiring sustained monitoring and community participation.
