Central Italy Confirms Three Local Dengue Cases

As of late July 2025, three confirmed, locally acquired cases of dengue fever were recorded in the Municipality of Budrio, located in central Italy.

As of July 24, 2025, as required by the Regional Arbovirus Plan, in collaboration with the Municipality of Budrio, disinfestations were carried out using larvicidal and adulticidal treatments to reduce the number of virus-carrying mosquitoes in the affected areas.

Budrio is located just east of Bologna, a city with about 390,000 residents in central Italy.

Additionally, diagnostic tests and access to a second-generation dengue vaccine have been offered to residents.

The Italian National Public Health Authority reported over 213 locally acquired dengue cases in 2024. Most of these cases were in DENV-2 cases, which were recorded in Fano, a small coastal city in Italy's Marche Region.

Compared with data from 2024, this was a significant increase from the 82 confirmed cases.

Currently, the U.S. CDC does not list Italy as a country at risk for dengue outbreaks. Nor does the CDC recommend dengue vaccination when traveling to at-risk areas. Only Puerto Rico offers dengue vaccinations in 2025.
