3 King County residents possibly exposed to hantavirus linked to infected cruise ship
KOMO • • general
Key Points:
- Three King County residents are being monitored for potential exposure to the Andes hantavirus linked to the MV Hondius cruise ship outbreak, which has caused at least three deaths, but no cases have been confirmed locally.
- Two residents were exposed on an airplane near an infected passenger and are asymptomatic, while a third, a cruise ship passenger, is being monitored at a national quarantine center; all are under close public health surveillance.
- Andes virus is unique among hantaviruses for its rare person-to-person transmission, typically requiring prolonged close contact, unlike the more common Sin Nombre virus in Washington, which spreads via rodent exposure.
- Symptoms of hantavirus infection appear 1–8 weeks after exposure and can progress from flu-like signs to severe respiratory distress; however, the current risk to the public remains low according to health officials.
- Experts emphasize that, despite some comparisons, the hantavirus outbreak differs significantly from COVID-19 in transmission and behavior, with no evidence of rapid spread similar to a pandemic.
