Ontario's chief medical officer says two residents who were on a cruise ship linked to a hantavirus outbreak are asymptomatic and isolating in their rural community.
Dr. Kieran Moore says the couple in the Grey Bruce Public Health region is being monitored for 45 days, the longest potential incubation period for the deadly virus.
Moore says the couple disembarked the cruise ship on the remote South Atlantic island of St. Helena in late April, then flew to Johannesburg, South Africa. An infected person was on that flight, exposing the couple in two settings.
There is very little risk to the general public in Ontario, Moore said.
Four other Canadians remain on board the MV Hondius. The ship has reported eight cases, including three deaths from the outbreak of the Andes virus, the only hantavirus known to transmit between humans. Consular officials are heading to the Canary Islands to meet the ship when it docks in Tenerife this weekend.
