Austria's BASG lists 16 Dutch regions with confirmed human West Nile virus infections
The agency's 27 October blood and tissue safety update names the Dutch areas with confirmed human cases and asks that they be considered in donor interviews and selection.
Austria's Federal Office for Safety in Health Care (BASG) has issued an updated safety notice on West Nile virus (WNV) in the Netherlands, published on 27 October 2026 under its blood and tissue category. The office said it had been informed of confirmed human WNV infections in a number of Dutch regions.
The regions listed are: The Hague agglomeration, Leiden agglomeration and the bulb-growing region, Arnhem/Nijmegen, Delft/Westland, Gooi and Vecht region, Greater Amsterdam, Greater Rijnmond, IJmond, Central North Brabant, North-East North Brabant, East South Holland, Overig Zeeland, South-East South Holland, South-West Overijssel, Utrecht and Veluwe.
BASG asks that these areas be given appropriate attention during donor history-taking and donor selection. The notice does not set out specific deferral periods or testing requirements; readers are referred to the attached safety warnings for further detail.
The page lists earlier Netherlands WNV updates dated 18 August and 4, 8, 14 and 21 September, and 5 October 2026, alongside the latest one of 27 October. Questions can be directed to BASG's haemovigilance mailbox. As general context, donor-safety measures for WNV commonly rely on travel-related deferral or testing of donations from affected areas.
