WHO alerts on 12th hantavirus infection linked to MV Hondius

The World Health Organization confirmed that a Dutch crew member of the cruise ship MV Hondius tested positive for the Andes strain of hantavirus, raising the total count to twelve cases. The patient is in isolation and Dutch authorities are conducting weekly testing of all evacuees.

Case detection and quarantine measures in the Netherlands

During a press conference in Geneva, Tedros Adhanom Ghebreyesus urged all nations to keep monitoring passengers from the ship for the remainder of the quarantine period. The Dutch National Institute for Public Health and the Environment (RIVM) reported that the infected individual was admitted to hospital as a precaution and is now isolating at home.

Numbers of cases, contacts and fatalities

  • 12 confirmed hantavirus cases globally
  • 3 deaths reported to date
  • More than 600 contacts being followed in 30 countries
  • Two independent laboratories confirmed the positive test
  • Weekly testing continues for all evacuees from the Dutch‑flagged ship

Implications for European public‑health preparedness

The Andes strain is the only known hantavirus capable of human‑to‑human transmission, prompting heightened vigilance across Europe. While the RIVM notes the risk of further spread in the Netherlands remains very small, the episode underscores the need for rapid contact tracing, cross‑border coordination, and clear communication to prevent panic.

Outlook for containment and future monitoring

The WHO recommends continued surveillance of the 600+ contacts and advises countries to maintain quarantine protocols for any new symptomatic individuals. With no deaths reported since May 2 and the infected crew member isolated, experts expect the outbreak to be contained, but they caution that ongoing monitoring is essential to detect any potential secondary transmission.
