# Oregon clinician alert for possible MV Hondius Andes virus exposures

Oregon Health Authority · State clinician alert

## Summary

Oregon Health Authority issued a clinician alert on Andes virus in patients returning from the MV Hondius cruise event. The alert said no exposed individuals had returned to Oregon at that time and that any exposed individuals returning to Oregon would be actively monitored for symptoms through 42 days after last exposure.

## Safe interpretation

Clinician/public-health readiness notice only. It is not an Oregon case report, local transmission marker, or live public risk feed.

This record is a reviewed public health map note. It is not live surveillance, medical advice, patient-location tracking, or county-level risk prediction.
