A case of locally acquired dengue fever has been diagnosed in Sanremo, Italy, in a 30-year-old tourist with no recent international travel. Epidemiological investigations suggest the infection may have occurred in Salento, where a relative residing in Milan is also exhibiting compatible symptoms. Health authorities have implemented pest control measures in Sanremo.
The need for active surveillance and improved diagnostic capabilities in Italy is highlighted, given the possibility of local transmission of the virus, and recalling previous outbreaks in 2024 and 2025.
