气候变暖推动基孔肯雅热北移，欧洲大部分地区已具传播条件

Core Insights - A recent study indicates that climate change and the spread of invasive mosquito species have created conditions for Chikungunya virus to spread across much of Europe, with researchers warning that further northward expansion is "only a matter of time" [1][2] Group 1: Climate Impact on Disease Spread - The study published in the Journal of the Royal Society Interface systematically assessed the impact of temperature on the incubation time of the virus within the Asian tiger mosquito, finding that the minimum temperature threshold for virus transmission is now estimated to be 13°C to 14°C, approximately 2.5°C lower than previous estimates [1] - In southern European countries like Spain, Portugal, Italy, and Greece, the annual transmission window for Chikungunya has exceeded six months, while in Belgium, France, Germany, and Switzerland, it ranges from three to five months [2] Group 2: Public Health Implications - The World Health Organization experts emphasize that climate factors significantly influence mosquito-borne virus transmission, but there remains an opportunity for Europe to curb the spread through mosquito control, enhanced monitoring systems, and public education [2] - The UK has not yet reported local transmission cases, but record-high imported cases were noted in the first half of 2025, indicating a rising risk if the Asian tiger mosquito successfully establishes itself [2] - Researchers highlight that as Europe warms at nearly twice the global average rate, diseases like Chikungunya and dengue are gradually altering their geographical boundaries, with signs of year-round mosquito activity observed in some southern regions [2]
