Medical News: European health authorities are on high alert after a KLM Royal Dutch Airlines flight attendant in the Netherlands was hospitalized following contact with a passenger later confirmed to have died from the rare Andes strain of hantavirus. The alarming development has intensified fears because the Andes variant is the only known hantavirus capable of limited human-to-human transmission but has a very long incubation period of between 2 to 8 weeks.

human transmission
The case has triggered urgent international contact tracing operations involving passengers, airline crew members, cruise ship travelers, and health authorities across Europe, South Africa, and South America.
Deadly Illness Begins on Antarctic Cruise
The outbreak is linked to the Dutch-flagged expedition cruise ship MV Hondius, which departed Ushuaia, Argentina, on April 1. During the voyage, a 69-year-old female passenger and her husband reportedly became ill after spending time in remote regions of Argentina where the Andes hantavirus strain is known to circulate among rodent populations.
Just days into the cruise, the husband’s condition rapidly worsened and he died aboard the vessel. Despite the medical emergency, the cruise continued until it reached St Helena on April 24, where the man’s body was taken ashore.
The woman accompanied her husband’s remains before boarding a regional Airlink flight to Johannesburg, South Africa.
Passenger Removed from KLM Flight
By the time she arrived in Johannesburg, the woman was already suffering from severe gastrointestinal symptoms and appeared visibly unwell. She later boarded KLM flight KL592 bound for Amsterdam Schiphol Airport on April 25.
Cabin crew members reportedly became increasingly concerned about her deteriorating condition while she was on board the packed Boeing 777-300 aircraft. Shortly before departure, the decision was made to remove the passenger from the flight due to her medical condition.
The woman was rushed to a Johannesburg hospital the following morning but died later that same day.
Initially, doctors were uncertain about the cause of death. It took more than nine days for PCR testing to confirm hantavirus infection, and further analysis later identified the Andes strain, a highly unusual and closely monitored variant.
Dutch Air Crew Member Falls Ill
According to Dutch media reports, one KLM flight attendant who had direct interaction with the woman in Johannesburg has since developed mild symptoms. The crew member has now been transferred to Amsterdam UMC medical center, where she remains in isolation while undergoing extensive testing for possible hantavirus infection.

ort notes that Andes hantavirus infections are considered particularly dangerous because, unlike most hantavirus strains, transmission between humans has been documented in rare cases involving close contact.
The Dutch National Institute for Public Health and the Environment has since launched a large-scale tracing effort involving everyone aboard flight KL592, including passengers traveling under Air France, Delta Air Lines, and SAS codeshare bookings.
International Authorities Race to Contain Risks
South African authorities are also tracing all passengers and crew from the Airlink flight between St Helena and Johannesburg, which carried 82 passengers and six crew members.
So far, three individuals connected to the cruise outbreak have died, while another passenger remains critically ill in intensive care. Several others required emergency medical evacuation during the past week.
Health experts stress that person-to-person transmission of Andes hantavirus remains extremely rare and usually requires prolonged close exposure. However, the delayed diagnosis, combined with international air travel and cruise ship exposure, has raised serious concerns among infectious disease specialists. Authorities are now carefully monitoring airline staff, passengers, and cruise contacts for any signs of secondary infections, as even a small cluster of additional cases could significantly heighten global concern surrounding the outbreak.
