West Nile Virus Surge in Italy: Cases Rise in Rome and Prevention Tips

Health authorities in Italy have confirmed the first two cases of West Nile virus in Rome, marking the expansion of the virus into the capital city.

The virus is transmitted to humans through the bites of infected mosquitoes. While most infections are mild, the ISS has urged the public to proteggersi il più possibile dalle zanzare, or protect themselves as much as possible from mosquitoes, to curb the spread.

West Nile Virus Case Numbers and Fatalities in Italy

The current outbreak has seen a steady rise in infections.

One of the recent fatalities was an 80-year-old retiree from Novara, as reported by La Stampa.

The arrival of the virus in Rome, confirmed by Tgcom24 and RomaToday, indicates that the virus is now present in one of Italy’s most densely populated urban centers, increasing the potential for further transmission.

Prevention and Repellent Guidelines

Public health guidance emphasizes the use of repellents to prevent mosquito bites. According to Mondosanità, the effectiveness of protection often depends on the choice of active ingredients in the repellent.

The publication identifies DEET and Icaridin as the primary options for users.

Beyond chemical repellents, health authorities recommend physical barriers.

Clinical Context of West Nile Virus

West Nile virus is a zoonotic disease, meaning it jumps from animals to humans. The virus primarily circulates between birds and mosquitoes. Humans become accidental hosts when bitten by a mosquito that has fed on an infected bird.

Most people infected with the virus do not develop symptoms or experience a mild fever. However, a small percentage of patients develop severe neuroinvasive disease, such as encephalitis or meningitis, which can lead to permanent neurological damage or death.

The risk is typically higher during the summer and early autumn months when mosquito populations peak.
