A Dutch cruise ship with nearly 150 people on board including 17 Americans is waiting for help off Cape Verde after a suspected hantavirus outbreak killed three passengers. The World Health Organization and the ship's operator reported the deaths and illnesses. The MV Hondius was on a polar cruise from Argentina to Antarctica and several South Atlantic islands. A 70-year-old Dutch man was the first victim. His wife also died after being transferred to South Africa. A British man tested positive and is critically ill in a hospital. The ship was seeking assistance on Monday from Cape Verde, but no one has been allowed to disembark.
