Britons traveling abroad this summer may encounter dangerous mosquito-borne illnesses that have been spreading in popular European vacation spots. The mosquito season is currently active across the continent as rising temperatures provide ideal conditions for diseases like dengue fever and chikungunya to thrive. These viruses have the potential to cause paralysis, vision impairment, joint pain, and even death.
The transmission of these viruses occurs when mosquitoes bite infected animals before biting humans, thus passing on the disease. There have been approximately 1,000 suspected cases of these illnesses in prominent British holiday destinations such as Spain, France, Italy, Portugal, and Greece.
Italy has reported 38 fatalities from West Nile infections, according to MailOnline. The European Centre for Disease Prevention and Control has noted a resurgence of West Nile virus cases this summer, with instances identified in Florence and Verona. Romania and North Macedonia have also confirmed three infections collectively. The West Nile virus, originally discovered in Uganda in 1937, has since spread to Europe.
While many infected individuals exhibit no symptoms or only mild illness, about one in 150 people develop severe complications such as deadly meningitis and encephalitis, which can lead to brain inflammation and spinal cord issues.
Less common but still concerning, Dengue fever has shown up with 19 suspected cases in France, along with four in Italy and two in Portugal. Symptoms typically include flu-like signs such as high fever, headaches, swollen glands, rashes, and joint pain. In severe cases, patients may experience bleeding in vomit or stool. The World Health Organization estimates that there are between 100 million and 400 million dengue infections worldwide each year.
Experts have expressed heightened alarm about disease-carrying mosquitoes due to escalating temperatures caused by climate change. Professor Rachel Lowe, from the global health resilience group at the Barcelona Supercomputing Center in Spain, highlighted the impact of global warming on disease vectors like malaria and dengue fever. She emphasized that longer hot seasons will extend the window for mosquito-borne disease spread, leading to more frequent and challenging outbreaks in new regions.
