Italian health authorities are observing that rising temperatures and longer warm seasons are aiding the spread of the West Nile virus by mosquitoes. This year, Italy has reported over 650 infections, making up about half of Europe’s cases. The virus, endemic in Italy since 2020, is now seen every summer and early fall. While most infected people show no symptoms or only mild flu-like symptoms, severe complications can occur in some cases. Warmer weather extends the mosquito season, sometimes until November, allowing the virus to spread to new areas. Italy’s extensive monitoring system helps detect many cases, drawing interest from other European countries. The Netherlands has also reported cases and deaths this year. Experts warn that climate change could lengthen mosquito seasons, increasing virus survival and spread.
