Public Health Alerts – Guidance for PHAC-OMD
Public Health Alerts is an application on CNPHI that allows for the timely notification and/or dissemination of information between local/regional, provincial/territorial and national public health stakeholders. Users can select the target audience (single P/T, multiple P/Ts, national) to whom an email notification will be sent to advise that a new PHA has been posted. PHAs are used for case finding and to provide situational awareness on current national, provincial/territorial and local investigations.
The Enteric Public Health Alerts System (EPHAS) was developed by a local, provincial and federal working group and was launched in August 2001 on CEOSC (Canadian Enteric Outbreak Surveillance Centre) and then moved to CIOSC (Canadian Integrated Outbreak Surveillance Centre), housed on CNPHI (Canadian Network for Public Health Intelligence), in 2003. Many people still refer to PHAs as “CEOSC postings” or “CEOSC alerts”.
