A study warns that climate change could enable the Chikungunya virus, spread by Aedes mosquitoes, to reach Europe and North America. Scientists predict that rising temperatures will allow mosquito vectors to thrive in previously unsuitable regions, increasing the risk of outbreaks in temperate areas by 2100.

• 01Chikungunya virus is primarily spread by Aedes mosquitoes, with the Asian tiger mosquito being a significant vector.
• 02Currently, 139 regions globally are at risk for Chikungunya, which could expand to temperate areas due to climate change.
• 03The virus is not fatal but can cause severe joint pain and disability, with a notable rise in cases reported in the UK.
• 04Public health officials are advised to prepare for potential outbreaks by monitoring mosquito populations and training healthcare providers.
• 05The study suggests that without action to limit climate change, future outbreaks could escalate in regions like northeastern North America and central Europe.

The spread of Chikungunya could lead to increased public health challenges in Europe and North America, particularly in areas unaccustomed to the virus.
