Hantavirus Outbreak on MV Hondius Sparks Global Health Response as New Cases Emerge During Evacuations

Tenerife, Spain : An international health response is underway after a hantavirus outbreak aboard the Dutch expedition cruise ship MV Hondius led to multiple deaths, emergency evacuations, and new suspected infections during repatriation flights.

The World Health Organization (WHO) has classified everyone onboard the vessel as ‘high-risk contacts’ and recommended a 42-day monitoring period for all passengers and crew. 

Fresh concerns emerged after a French passenger developed symptoms while being flown from Tenerife to Paris. French authorities immediately placed all five evacuees from the flight into strict isolation upon arrival. Medical teams in protective equipment escorted the passengers to Bichat Hospital in Paris, where they will undergo testing, quarantine, and long-term monitoring.

U.S. authorities also confirmed that one American passenger began showing mild symptoms during evacuation, while another tested mildly positive for the Andes strain of hantavirus, a rare variant capable of limited human to human transmission. Both passengers were transported in specialized aircraft biocontainment units as a precaution.

Several countries including France, Spain, the United States, the United Kingdom, the Netherlands, Australia, Turkey, and Ireland have carried out evacuation flights for stranded passengers. Spain quarantined returning citizens at a military hospital in Madrid, while British passengers flown to Manchester are being closely monitored despite showing no symptoms so far.

Despite the escalating response, US health officials said American evacuees may not automatically face mandatory quarantine. Instead, the Centers for Disease Control and Prevention (CDC) will conduct individual risk assessments to determine whether home isolation or stricter measures are necessary.
