Hospital treating MV Hondius patients quarantines 12 staff after protocol breach
- On May 12, Radboudumc in Nijmegen said it quarantined 12 staff members after blood and urine from an MV Hondius hantavirus patient were handled improperly. - The hospital said the 12 workers will remain in preventive quarantine for six weeks, while board chair Bertine Lahuis said the infection risk was “very low.” - WHO and national health authorities are continuing case counts, contact tracing and monitoring tied to the MV Hondius outbreak.
Radboud University Medical Center, known as Radboudumc, said on May 12 that it had placed 12 staff members in preventive quarantine after blood and urine from a hantavirus patient linked to the MV Hondius cruise ship were handled without the strictest protocols. The hospital, in Nijmegen in the eastern Netherlands, said the quarantine would last six weeks. Bertine Lahuis, chair of the hospital’s executive board, said the risk of infection was “very low,” but called the episode significant for those involved. The case has drawn attention because the patient came from the MV Hondius outbreak, which the World Health Organization and the U.S. Centers for Disease Control and Prevention have linked to the Andes strain of hantavirus, a form associated with limited person-to-person transmission. ### Which hospital quarantined staff, and what exactly went wrong? Radboudumc said 12 employees were quarantined after procedural errors were made while caring for a hantavirus-positive patient evacuated from the MV Hondius. The hospital said the mistakes involved handling blood samples and disposing of the patient’s urine under standard procedures rather than stricter measures required for this case. (whtc.com) Bertine Lahuis said the hospital regretted what happened and would investigate the sequence of events. The hospital said patient care continued uninterrupted despite the quarantine. ### Why are 12 healthcare workers being isolated for six weeks? The 12 staff members were placed in preventive quarantine for six weeks because they were identified as having possible exposure during the protocol lapse, the hospital said. (straitstimes.com) Radboudumc said the actual risk of infection was low, but it still chose monitoring and follow-up because of the virus involved. Six weeks aligns with the monitoring window officials are using around the outbreak. (dutchreview.com) Reuters reported that the quarantine of the medics showed the difficulty hospitals faced in quickly introducing stricter protocols for the hantavirus strain tied to the cruise-ship cluster. That is Reuters’ characterization of the operational challenge, not a statement by the hospital. (english.news.cn) ### How is this connected to the MV Hondius outbreak? The patient treated at Radboudumc had spent time on the MV Hondius, the Dutch cruise ship at the center of a multi-country hantavirus investigation. WHO said on May 4 that the ship was carrying 147 passengers and crew when a cluster of severe respiratory illness was reported. As of that WHO update, seven cases had been identified, including three deaths. (whtc.com) The CDC said on May 6 that WHO had confirmed the outbreak strain as Andes virus. The CDC added that, as of May 8, WHO had reported eight cases — six confirmed and two suspected — including three deaths. Later Reuters reporting said WHO’s confirmed-case tally rose to nine, though the agency did not identify the new cases in that account. ### Why are health officials treating this outbreak differently from many other hantavirus cases? (who.int) The CDC said Andes virus is the type responsible for the 2026 cruise-ship outbreak, and that investigations were continuing to assess exposure risks for U.S. passengers and others who may have been exposed on flights. WHO has described the event as a multi-country cluster under investigation. Reuters and other outlets have focused on Andes virus because it is associated with limited person-to-person transmission, unlike the more common pattern of hantavirus spread through rodent exposure. (cdc.gov) That distinction is central to why hospitals and public-health agencies have tightened handling, isolation and tracing procedures around the Hondius-linked patients. ### Did the hospital say care was disrupted? (cdc.gov) Radboudumc said patient care continued uninterrupted even after 12 staff members were removed from duty and placed in quarantine. The hospital did not publicly detail which departments were affected or whether replacement staffing had to be brought in. Twelve workers is still a meaningful staffing number for a single exposure event, and the hospital said the measures had a “significant impact on everyone involved.” That quote came from Lahuis in the hospital’s account of the incident. (cdc.gov) ### What happens next in the Hondius-linked investigation? WHO, the CDC and national health authorities are still updating case totals and tracing exposures tied to the cruise ship and related travel. (whtc.com) The CDC’s May 6 health notice said investigations were ongoing for American passengers and for people who may have been exposed to infected cruise-ship passengers on aircraft. At Radboudumc, the next step is the hospital’s investigation into how the blood-handling and urine-disposal lapses occurred, while the 12 quarantined staff members complete six weeks of monitoring. (english.news.cn) WHO’s outbreak page remains the main public reference point for official international updates on the cluster. (dutchreview.com) (cdc.gov)
