An American oncologist became a doctor on the cruise ship MV Hondius after the ship's doctor was infected with hantavirus.

On the cruise ship MV Hondius, an outbreak of hantavirus has led to the infection of a doctor on board, who is among the six people tested positive. Dr. Stephen Kornfeld, an American oncologist, has taken the lead in responding to the medical crisis, intervening quickly after the situation worsened. One patient has died, and others have been hospitalized in various countries. The ship's doctor and a guide are in isolation in the Netherlands, while other patients are hospitalized in South Africa and Switzerland. Although he feels vulnerable, Kornfeld is optimistic and in good condition. All passengers are considered high-risk contacts and will be monitored for 42 days. The U.S. Centers for Disease Control will evaluate Americans upon their return, without mandatory quarantine.
