Spain closes hantavirus case after last quarantined passengers test negative

Spain’s Health Ministry has closed the domestic hantavirus response linked to the MV Hondius cruise-ship cluster after the last 11 Spaniards under quarantine tested negative on their final PCR and completed the full 42-day monitoring period.

The move marks the end of Spain’s public-health response to the ship-related incident. According to reporting from El País, the remaining isolated passengers also completed the last 14 days of monitoring at home, and the ministry considered the episode closed.

How the case unfolded

The outbreak concern began after the Dutch expedition ship MV Hondius, which had departed Ushuaia, Argentina, in April, became linked to hantavirus infections during the voyage.

Spanish authorities began tracking exposed passengers after the ship’s passengers and crew were identified as part of an international public-health alert. Earlier reporting said Spanish passengers linked to the vessel were transferred from Tenerife to Madrid’s Gómez Ulla military hospital on May 10 before continuing quarantine under ministry protocol.

Two Spaniards from the same cluster later tested positive with mild symptoms. The first was discharged on June 4 after recovering, and the second was discharged on June 16.

Final negative tests

On June 20, the last 11 Spaniards who had remained in quarantine tested negative on the final PCR, according to El País. The same report said the 38 Filipino crew members linked to the ship also returned home without additional detected infections.

Five Catalan contacts who had also been linked to the ship had already tested negative and gone home on June 7 to finish the monitoring period there.

Why the episode drew attention

The ship cluster attracted international attention because it involved the Andes strain of hantavirus, the rare type known for the possibility of person-to-person spread through close and prolonged contact.

That risk led authorities to monitor passengers who had already disembarked before the diagnosis was confirmed, while Spain completed the quarantine period for those assessed as exposed.

With all remaining Spanish quarantines now complete and final tests negative, Spain’s domestic case management is over. Further follow-up would only be needed if new cases emerge elsewhere in the broader contact-tracing effort.
