Each summer, the ancient negotiation between human settlement and the insect world resumes — but in 2026, the terms have shifted. West Nile virus has reached its highest early-season case count in over two decades, with an unusual proportion of infections striking the nervous system, while Eastern equine encephalitis continues its grim arithmetic of one-in-three fatalities. Drought and warmth have conspired to concentrate the conditions that accelerate transmission, and with no vaccines or antivirals in existence for either disease, the only shield available is human behavior itself.

Households face increased healthcare costs from hospitalizations and long-term disability care; productivity losses from illness; higher insurance premiums; increased spending on mosquito repellents and protective measures; potential wage losses from severe neurologic complications causing permanent disability.
Likely increased public health spending on vector control and surveillance; potential regulatory expansion of pesticide use; possible insurance policy adjustments; workplace safety protocols may be strengthened; climate adaptation policies may be accelerated given disease-climate linkage.
