The West Nile virus outbreak spreading across the Netherlands has intensified, with confirmed infections reaching 28 cases and deaths climbing to 4 as of September 17 1. The latest fatality represents a rare case of transmission through blood transfusion, with the patient dying after receiving blood from an infected donor, while the remaining 27 infections resulted from mosquito-borne transmission 1.

The virus has been detected across multiple regions in the Netherlands, including Utrecht, North Brabant, North Holland, South Holland, Overijssel, and Gelderland provinces 1. Among those infected, approximately 80 percent show no symptoms, while about 20 percent develop West Nile fever or West Nile virus neuroinvasive disease 1. Older adults aged 50 and above, as well as immunocompromised individuals, face elevated risk of severe illness 1.

Dutch health authorities are closely monitoring the situation and stated they will implement appropriate measures as circumstances warrant 1. The country's first West Nile virus cases since 2020 were initially reported in August 1.
