Eight West Nile Virus Fatalities Confirmed in Italy in 2025

Since the beginning of 2025, five countries in Europe have reported human cases of West Nile Virus (WNV) infection: Bulgaria, France, Greece, Italy, and Romania.

In week #31, the European CDC reported that the highest number of cases, 43, occurred in the Latina province of Italy.

As of July 31, 2025, a total of 89 cases of WNV infection have been confirmed (Bollettino N. 3) in Italy this year, including eight fatalities.

In addition to WNV, other mosquito-borne diseases, Chikungunya and Dengue, have been reported in Italy in 2025.

Before visiting Italy this summer for events such as the Jubilee of Youth, the U.S. CDC recommends speaking with a travel vaccine advisor at least one month before departure about immunization options.
