On Sept. 3, 2025, Navy hospital here is warning people to take precautions against West Nile virus after a confirmed case of the illness among its military community.

U.S. Naval Hospital Naples officials confirmed a single case of the infection among Navy personnel in a Facebook post last week. The hospital cautioned that while the overall risk for contracting the virus was low, “continued vigilance is important.”

“Prevention is key,” the hospital said in the Aug. 28 post, adding that people should wear long-sleeved shirts and long pants, and consider wearing a mosquito repellent, among other precautions, to lessen the risk of infection.

The hospital also said it was using traps to monitor and reduce the mosquito population on the Naval Support Activity Naples Support Site where service members and their families live, work and shop.

As of Aug. 28, there had been 67 human cases of West Nile in the Campania region where NSA Naples is located, with 39 of those reported in the city of Naples, the hospital said in its Facebook post.

The first confirmed case of West Nile in Pordenone Province, where Aviano Air Base is located, was reported last week in the commune of Azzano Decimo, according to Italian news media reports.

There have been 10 deaths related to West Nile in Italy, according to the European Centre for Disease Prevention and Control and European Food Safety Authority report, which also indicated that the number of cases this year were slightly above average for the last decade but remained lower than 2024 and 2018.
