Public health officials in Seattle and King County are monitoring three local residents for potential exposure to the Andes strain of hantavirus. The concern stems from a recent outbreak aboard the MV Hondius cruise ship, which has killed three people and sickened several others. While the risk to the general public remains very low, authorities are taking precautions because this specific strain is the only version of the virus known to spread between humans.
Key Details:
- The Exposure: Two of the residents were exposed during a flight from South Africa to Amsterdam, where they sat near an infected passenger who was removed from the plane before takeoff. The third resident was a passenger on the MV Hondius cruise ship itself.
- Current Status: None of the three individuals have tested positive for the virus or shown any symptoms. The former cruise passenger is currently being monitored at a federal quarantine facility in Nebraska, while the other two are isolating at home in King County.
- A Rare Threat: While most hantaviruses are only caught through contact with rodent droppings, the Andes virus can spread through close, prolonged person-to-person contact. This led to the rigorous contact tracing currently underway.
- Public Health Reassurance: Health officials have stressed that this is not a “new COVID-19” scenario. They have decades of research on hantavirus, and its transmission is much less efficient than respiratory viruses like the flu or coronavirus.
- Global Context: The outbreak on the MV Hondius (which traveled from Argentina to remote Atlantic islands) has resulted in 11 reported cases worldwide. The World Health Organization (WHO) and the CDC are working together to track all passengers who may have been exposed during the voyage or subsequent travel.
