Current outbreaks

Last update: July 2, 2025

When is an outbreak declared in a long-term care or assisted living site?

An outbreak may be declared at the direction of the medical health officer or their official designate. Based on the consideration of multiple risk factors, the severity of illness amongst cases and the rate of increase in cases, a care neighborhood may be placed on outbreak measures under the direction of the medical health officer working with the site leadership, long-term care program and infection prevention and control.

When is an outbreak declared in an acute care site?

Determination and declaration of an outbreak is made by the medical health officer or their official designate (i.e., medical microbiologist in acute care).

An outbreak is declared when there is evidence of increased incidence or transmission of health care-associated cases of an infectious pathogen among admitted patients.
