Heat may bring chikungunya virus to Europe, study warns

New study warns climate change could push chikungunya-carrying mosquitoes into Europe and North America.
Warmer temperatures may expand mosquito habitats and speed virus development, increasing outbreak risk.
The study projects future hotspots in north-central Europe, northeastern North America, and eastern Asia by 2100.
Indigenous transmission is not yet established in Europe or North America; cases are travel-related.
Researchers used geo-tagged records of virus and vector presence across the globe to model spread.
The 2025 global chikungunya tally was over 500,000 cases with hundreds of deaths, underscoring rising risk.
Health systems are urged to prepare with surveillance, clinician training, and rapid-response plans before outbreaks.
Countries at risk—UK, Germany, the US, China, and Japan—should prioritize pre-emptive vector surveillance.
The study analyzed 16 IPCC climate scenarios to project disease expansion by 2100.
The study emphasizes proactive public health steps to avoid panic and outbreaks.
