Spread of West Nile virus confirmed in Italy, resulting in 32 cases and claiming 2 lives among affected individuals
In a recent development, Italy has reported 32 confirmed cases of the West Nile Virus (WNV), including two deaths, as of July 2025 [1][4][5]. This marks a significant presence of the virus, primarily transmitted through infected mosquitoes during warmer summer months.
The majority of cases have been concentrated in the Lazio region of Italy [1][4], with most of the Italian cases identified in the province of Latina, which is approximately 100 kilometers south of Rome. This region has reported 12 new cases on Thursday alone.
The West Nile Virus, a member of the Flaviviridae family, was first isolated in Uganda's West Nile district in 1937. It is endemic in Italy for several years now, according to Anna Teresa Palamara, director of the Italian National Health Institute (ISS)'s infectious diseases department [2].
Given that WNV is transmitted by mosquitoes feeding on infected birds, prevention focuses on minimizing exposure to bites and controlling mosquito populations. Among the confirmed cases, 80 per cent are asymptomatic [2]. However, the specific details on how to keep mosquito-borne diseases in check were not provided in the article.
To combat the spread of WNV in Italy, public health advisories urge avoiding mosquito bites, especially in affected regions, by using insect repellent and wearing protective clothing. Vector control efforts such as mosquito monitoring and reduction programs have been implemented by health authorities. Travelers and residents are advised to stay informed about local outbreaks and follow health ministry recommendations [1].
The West Nile Virus has also been reported in the regions of Piedmont, Veneto, Emilia-Romagna, and Campania. Mosquito-borne diseases are a growing problem in Europe, and the current distribution of WNV cases suggests a wider geographical spread this summer [5].
It's important to note that there is no risk of person-to-person contagion of the West Nile Virus. The main form of spread to people is through the bites of infected mosquitoes. The risk of serious consequences from the West Nile Virus is greater for the most fragile people. Wild birds and mosquitoes, most frequently of the Culex type, serve as reservoirs for the West Nile Virus.
In the UK, the West Nile Virus has been confirmed in mosquitoes for the first time, with the spread potentially linked to climate change. While a vaccine for humans is not widely available, preventing bites remains the key to reducing transmission risk.
In conclusion, while the West Nile Virus remains a regional health concern in Italy, public health efforts emphasize mosquito control and personal protection to reduce transmission risk [1][4][5]. It is crucial for individuals to stay informed about local outbreaks and take necessary precautions to protect themselves.
Science has shown that the West Nile Virus is transmitted by mosquitoes, which are also responsible for spreading the health-and-wellness issue of the West Nile Virus. To combat the spread of the West Nile Virus, science-based prevention includes minimizing exposure to bites and controlling mosquito populations, which can potentially reduce the number of health-and-wellness issues related to the virus.
