How to interpret this page

What the Washington marker means

It is a reviewed public summary or official source link for map context.

It is not a statement that current exposure risk exists at any exact address, county, park, workplace, or travel stop.

For current public health action, use the linked official agency sources and local health authorities.

Limits

Known limitations

  • Annual range statements are not a current case count.
  • No county risk map is inferred from state source text.

Washington separates MV Hondius Andes exposure monitoring from unrelated Sin Nombre event

Washington DOH said it was assisting with two separate hantavirus-related investigations: three King County residents potentially exposed to Andes virus linked to the MV Hondius event, and a separate unrelated local hantavirus infection. DOH emphasized that the virus strains and exposure circumstances were different and not connected, and that public risk remained very low.

State response update only. Andes virus exposure monitoring and routine Sin Nombre virus risk must remain separated; this is not a Washington live case feed, patient-location dataset, or evidence of local Andes virus spread.
