Italy has recorded 41 deaths and 594 cases of West Nile virus, according to O GLOBO. The Brazilian outlet reported the figures on Thursday, September 10, 2026. CNN Portugal also reported that Italy had raised its death toll to 41 and confirmed close to 600 cases.
The scale of the Italian outbreak stands in contrast with the situation reported in Brazil. According to n1n.com.br, Brazil has registered four cases and one death from the virus in 2026. The Paraná state health department has also published information on West Nile fever, and the city government of Porto Ferreira has issued a prevention alert against the disease.
West Nile virus is transmitted mainly through mosquito bites, which is why public health authorities in affected areas focus on mosquito control and on advising residents to avoid bites. The reporting above does not specify which Italian regions are most affected, how the current season compares with previous years, or what measures Italian authorities have taken in response.
What to watch next: whether Italian health authorities release regional breakdowns or updated counts, and whether Brazilian officials report additional cases beyond the four confirmed so far.
