Outbreak Management

The OMT works in collaboration with external and internal partners to investigate, manage, and control a suspect or confirmed outbreak. To provide a comprehensive approach to outbreak management, each facility should strive to have a representative from all departments in addition to the IPAC Lead as a member of the OMT.

The OMT is encouraged to meet daily during an outbreak to ensure the following:

1. Line listings are accurate and updated daily.
2. Cases added to the line list(s) meet outbreak definition.
3. Surveillance is being conducted.
4. Outbreak control measures are being implemented and maintained.
5. Provide adequate coverage for staff absences (i.e., designate an alternate person who is knowledgeable of the outbreak process to fax inline listings).
6. Communicate effectively with staff, residents, families, and volunteers.

Prompt reporting of an outbreak results in a rapid response in the initiation of infection prevention and control (IPAC) measures. This can help to decrease the length and severity of the outbreak.

Healthcare facilities and institutions are legally required to report outbreaks. If you suspect an outbreak, fax a completed initial Comprehensive Line List to WECHU at 519-977-5097.

Contact the Infectious Disease Prevention (IDP) Hotline to discuss outbreak management and control measures with a member of the IPAC Hub Team.

Track and monitor client and staff cases on line listing forms. Fax the Comprehensive Line Listbefore 10:00 AM daily; including on holidays and weekends to 519-977-5097.

ONLY add clients and staff to line listing that meet the WECHU-provided case definition.

Fax in a “No New Cases” line listing if all clients and/or staff are removed, or no symptomatic clients and/or staff are identified during the outbreak.

Notify the WECHU of all line listed clients and staff who are hospitalized.

Notify the WECHU of all line listed client or staff deaths.

Notify the WECHU of all line listed clients and staff with chest x-ray confirmed cases of pneumonia.
