Canada's Chief Public Health Officer Discusses National Guidance for Hantavirus Exposure Risk Stratification Following Cruise Ship Cluster

Canada's chief public health officer Dr. Joss Reimer announced that national health authorities are developing coordinated guidance on managing hantavirus exposures of varying risk levels. The initiative follows a cluster of hantavirus cases connected to a cruise ship outbreak. Working with provincial and territorial counterparts, the team is establishing protocols for risk stratification and testing approaches to ensure consistent public health response across Canada. The focus on 'low-risk' exposures suggests public health teams are working to refine exposure definitions and avoid unnecessary testing while maintaining surveillance for higher-risk contacts.
