90-Second Read: Bend doctor tells CNN he tested positive for Hantavirus

A retired Bend doctor who was on a cruise ship where three people died after contracting the Hantavirus says he too has tested positive for the dangerous virus. Health authorities say it is the first Hantavirus outbreak on a cruise ship. Now, he is one of 18 Americans under observation at specialized healthcare facilities designed to treat people with dangerous infectious diseases after three people died and others were sickened by a Hantavirus outbreak aboard the ship.

Kornfield said he felt ill on the ship and tested "faintly positive" before arriving back in the U.S. He expects more testing to be done in the next few days. The outbreak has now reached 11 total reported cases, 9 of which have been confirmed. The director of the World Health Organization said confirmed and suspected cases have only been reported among the cruise ship's passengers or crew.

A Dutch couple, identified by the WHO as the first cruise passengers infected with Hantavirus, spent several months in Argentina and neighboring South American countries before boarding the cruise ship. But the Andes virus detected in the cruise ship outbreak may be able to spread between people in rare cases. Three people on the cruise died, including a Dutch couple that health officials believe were the first exposed to the virus while visiting South America.
