Seven additional individuals in Ontario are now being told to isolate by provincial health officials after being linked to a global hantavirus outbreak originating from a cruise ship, as reported by The Canadian Press. These individuals are considered "low-risk" contacts, according to Jackson Jacobs, a spokesperson for Ontario's health minister.
Expansion of Isolated Contacts
The seven new cases bring the total number of people isolating in Ontario to ten, including three who were previously identified after exposure to the rodent-borne virus while traveling. All ten have been instructed to isolate for 45 days "out of an abundance of caution" and are under monitoring by local public health units. Additionally, six individuals are isolating in Alberta and British Columbia, remaining asymptomatic, according to provincial health officials. One person in Quebec connected to the outbreak is no longer isolating after being deemed a low-risk contact by the province's health ministry.
Understanding Risk Levels
A person is classified as "low-risk" if they came into contact with someone considered "high-risk." The three high-risk contacts in Ontario include a couple from Grey-Bruce County who were aboard the MV Hondius cruise ship and returned home on April 25, after disembarking on the island of St. Helena in the South Atlantic and flying to Johannesburg. A third person in Peel Region may have come into contact with a confirmed hantavirus case. All three shared a flight with a cruise passenger who later died of hantavirus. They remain asymptomatic, Jacobs confirmed.
Global Impact of the Outbreak
Globally, the hantavirus outbreak has claimed three lives, with 11 confirmed infections. During a news conference in Madrid, World Health Organization Director-General Tedros Adhanom Ghebreyesus stated that there is currently "no sign of larger outbreak, but of course the situation could change and, given the long incubation period of the virus, it's possible we might see more cases in the coming weeks." The MV Hondius was sailing from Argentina to Cape Verde when the outbreak was detected in early May. Three passengers have died, and the number of positive cases has grown to 11 internationally.
Public health officials and infectious disease physicians emphasize that the Andes virus, the type of hantavirus involved, requires close and prolonged contact to spread and is not considered a pandemic threat.
