Households face increased healthcare expenses, potential illness-related income loss, higher insurance premiums, and reduced outdoor activities during peak season. Vulnerable populations (elderly, immunocompromised) face elevated medical costs.
Likely increased government spending on vector control programs, public health campaigns, and emergency response. Potential regulatory changes to pesticide use, water management policies to reduce breeding grounds, and climate adaptation strategies. May accelerate discussion of climate change mitigation policies.
