Britons travelling abroad this summer could be at risk of deadly mosquito-borne diseases sweeping through European holiday hotspots each summer.Mosquito season is now entering its peak months, with soaring temperatures creating ideal breeding conditions and increasing the risk of viruses such as West Nile, chikungunya and dengue fever spreading across the continent.These have been known to trigger debilitating joint pain, paralysis, vision loss and even death.The insects transmit the viruses by biting infected animals or people before passing the virus into humans' bloodstream through a subsequent bite.And the Daily Mail's interactive map shows that more than 1,000 suspected cases of these diseases were recorded across major European holiday destinations as of last summer, including Spain, Portugal, France, Italy and Greece - a pattern experts fear could become a more frequent occurrence. Around 38 people also died, most of them from West Nile virus infections in Italy. Official data from the European Centre for Disease Prevention and Control shows West Nile virus is already returning this summer, with cases detected in the Italian provinces of Caserta, Florence and Verona. Romania and North Macedonia have also reported a shared three infections.
