A KLM flight attendant from Haarlem has been hospitalized following contact with a hantavirus-positive passenger on a Johannesburg-based cruise ship. The 69-year-old Dutch woman died of the Andes variant of hantavirus in South Africa on April 26, and the flight attendant, who worked on the same KLM flight, is now in isolation at Amsterdam UMC with mild symptoms. Health authorities confirmed she is being tested for the virus, which has a 60-day incubation period. This case highlights the virus’s ability to spread through human-to-human contact, a rare trait of the Andes variant.

The hantavirus outbreak originated on the Dutch cruise ship Hondius, where three passengers, including the deceased Dutch woman and her husband, succumbed to the illness. The virus, transmitted via respiratory droplets in this instance, has infected seven people aboard the vessel. Health agencies are monitoring 150 remaining passengers, including 10 Dutch nationals, as the ship heads to Tenerife. Evacuations have already removed three infected individuals, with two hospitalized in Germany and the Netherlands. The British crew member Martin Anstee, also on the ship, is in isolation despite reporting no symptoms. The Andes variant’s person-to-person transmission raises alarms about potential spread beyond the cruise route.

The incident underscores the urgency of rapid testing and isolation protocols for travelers. While the flight attendant’s condition remains stable, the case serves as a stark reminder of hantavirus’s risks, particularly in confined settings like aircraft or cruise ships. Health authorities have not yet issued specific guidelines for passengers but are urging vigilance for symptoms like fever or respiratory issues. The case also raises questions about how airlines and cruise lines screen passengers for emerging pathogens. With the virus’s long incubation period, delayed symptoms could complicate containment efforts. The situation remains fluid, but the Andes variant’s behavior in this outbreak offers critical insights into managing zoonotic diseases in global travel.
