A suspected hantavirus outbreak aboard the cruise ship MV Hondius has killed at least three passengers and sickened several others, with health officials reporting two confirmed and five suspected cases off the coast of Cape Verde. World Health Organization and international authorities are investigating and evacuating the ill, but say the risk to the general public remains very low. Dr. Joseph Blondeau, Saskatoon clinical microbiologist and Head of Clinical Microbiology at RUH and the University of Saskatchewan, joins the show to explain what hantavirus is and how rare human-to-human spread is.
