氣候變化惹的禍😂: 歐洲遭受由昆蟲產生的熱帶疾病的大威脅

Europe at major threat of INSECT-BORN tropical diseases, scientists warn
Europe is on the cusp of a major health threat from dangerous tropical diseases as climate change shifts weather patterns across the continent and people move around more, scientists are saying.
The harsher winters and generally colder conditions of Europe have long meant that insects that spread deadly illness like dengue fever and West Nile fever simply can’t survive to pass infections on to new human hosts. While the tiny disease-carrying critters can travel the distance from outbreak areas into more northerly regions, they can’t cope with the sudden drop in temperatures when seasons change in Europe.
However, with climate change impacting on the temperature and rain patterns in Europe, scientists have issued a stark warning that this will have a major knock-on effect in providing the ideal hotter, wetter conditions for these insects to breed and spread.

Scientists presented new research about the alarming expansion of vector range at the European Congress of Clinical Microbiology and Infectious Diseases on Saturday. “The stark reality is that longer hot seasons will enlarge the seasonal window for the potential spread of vector-borne diseases and favor larger outbreaks,”warnedstudy author Dr Giovanni Rezza, director of the Department of Infectious Diseases at the Istituto Superiore di Sanita in Rome, Italy.

Alarmingly, Rezza added that“Mediterranean Europe is now a part-time tropical region,” in which these disease-spreading vectors “are already established.”

The last decade has seen outbreaks of tropical diseases in Europe as mosquitoes spread, ranging from dengue fever in France, to malaria in Greece. Cases of the incurable chikungunya virushave been reported in both Italy and France, after showing up for the first time in Europe in 2007. Meanwhile, the European Center for Disease Prevention and Control (ECDC) says that in 2018, transmission rates for West Nile fever were higher than in the previous seven years.

Experts on the spread of deadly tropical diseases have called for more efforts in monitoring the threat so as to be better prepared for warding off potential outbreaks.
