The article discusses how the climate crisis is enabling the transmission of chikungunya disease in southern Europe, including Greece, Spain, Italy, and Portugal, for over six months a year. Rising temperatures are altering the infection landscape, making these regions more susceptible to outbreaks. Notably, even northern European areas such as southeast England are beginning to face risks from this disease.

Scientists have issued warnings that continuous global warming is likely to lead to the spread of chikungunya to higher latitudes, increasing the potential for larger outbreaks. The study points to the invasive Asian tiger mosquito (Aedes albopictus) as a significant factor in the transmission of the virus, which is primarily active during daylight hours. Recent analyses have revealed that the virus can be transmitted at lower temperatures than previously understood, with the threshold for transmission now estimated to be around 13–14°C.

Understanding the implications of the chikungunya virus spreading into Europe is crucial for public health. As the climate crisis persists, adaptation measures will be necessary to manage and mitigate the risks associated with the virus, particularly in regions that are becoming newly susceptible due to changing climatic conditions. The article emphasizes the importance of monitoring mosquito populations and implementing preventative strategies to safeguard public health in affected areas.
