The Texas Department of State Health Services (DSHS) says two Texas residents who were aboard an expedition cruise ship linked to a hantavirus outbreak are currently symptom-free and being monitored as a precaution.

Three cruise ship passengers with suspected hantavirus infections are being flown to the Netherlands for treatment.

An autopsy has confirmed that Gene Hackman's wife, Betsy Arakawa, died from hantavirus pulmonary syndrome.
