Hantavirus context · Canada

Canada sits in the Americas, where hantavirus infection most often takes the form of hantavirus pulmonary syndrome (HPS), the cardiopulmonary form first recognised during the 1993 Four Corners outbreak.

Across this region the principal reservoirs are Sigmodontinae rodents — most notably the deer mouse (Peromyscus maniculatus) in North America and Oligoryzomys species across the Southern Cone. Human exposure typically happens through inhalation of aerosolized droppings, urine, or saliva from these rodents — most often in rural housing, agricultural buildings, or poorly ventilated indoor spaces with recent rodent activity.

How Canada is tracked

Signals are ingested every five minutes from a global feed of open news sources, geolocated to Canada, then de-duplicated by URL and headline. Each signal links back to its original report so you can verify the source.

For confirmed case counts and clinical guidance in Canada, consult your national public health authority and the World Health Organization. This page is a surveillance signal, not a diagnostic tool.
