Monitoring for Hantavirus Exposure in King County
SEATTLE — Health officials in Seattle and King County are keeping an eye on a fourth resident potentially exposed to the Andes type of hantavirus, which is associated with an outbreak linked to the MV Hondius cruise ship. This was reported on Friday.
The Washington State Department of Health, along with the Centers for Disease Control and Prevention, alerted local officials about this additional resident on May 14, as noted by Public Health – Seattle & King County.

This resident hadn’t been on the cruise ship itself but did share a flight from Johannesburg to Amsterdam with a passenger who was later found to be ill. Before the flight took off, this sick passenger was taken off the plane and subsequently tested positive for the virus.
It’s important to note that this infected individual started their travels long before health authorities reported the outbreak to the World Health Organization.
Fortunately, health officials indicate that the King County resident is at a low risk for infection since they weren’t seated close to the ill passenger. They’ve returned to King County, are asymptomatic, and are currently monitoring for any symptoms.
Earlier in the week, Public Health revealed that three other residents of King County were already under observation for possible exposure to the hantavirus. Two of them had been sitting near the sick passenger on that same flight. Both individuals have returned home, are symptom-free, and are monitored with the assistance of public health officials.
A third resident who was on the MV Hondius is also being observed, along with other passengers, at the national quarantine center located at the University of Nebraska Medical Center. Officials confirmed that this person, too, remains asymptomatic.
Currently, there are no reported cases of Andes-type hantavirus in King County, and no residents are exhibiting symptoms, so the public risk remains low.
Dr. Sandra J. Valenciano, the acting director for Public Health – Seattle & King County, commented on the situation, saying, “We were informed yesterday of a fourth individual with a low-risk exposure and were able to reach the resident today. All our residents are following public health protocols, and the risk to the King County community remains low.”
Valenciano emphasized that monitoring those exposed allows health officials to provide support while ensuring that any symptoms are detected early for a swift public health response.
While hantavirus infections are uncommon, they can lead to serious health issues. The virus is mainly transmitted through contact with rodents or their droppings, urine, or saliva. Health experts noted that the Andes virus is the only hantavirus known to spread through human contact, which typically occurs through close physical interaction or prolonged exposure in confined spaces.
