Canadian tests presumptively positive for hantavirus after cruise ship exposure

One of four Canadians isolating in British Columbia after exposure to a hantavirus outbreak aboard a cruise ship has tested presumptively positive. The person, from the Yukon, developed mild symptoms on Thursday including a fever and headache. Samples have been sent to a national microbiology lab in Winnipeg for confirmation. Provincial health officer Dr. Bonnie Henry says protocols were followed and three other isolating individuals remain under observation.
