Effective November 2, 2012, Public Health Ontario is introducing a new weekly report: the Ontario Respiratory Virus Bulletin. The Ontario Respiratory Virus Bulletin combines information formerly published separately in the Ontario Influenza Bulletin and Public Health Ontario Laboratory-Based Respiratory Pathogen Surveillance Report.
The Ontario Respiratory Virus Bulletin will be posted every Friday during flu season (November to April) and on alternate Fridays outside of flu season. Each weekly report provides a summary from the previous week, as well as cumulative results since the beginning of the current season.
Surveillance Services is committed to continuously evaluating and improving our reports to respond to field needs and ensure timely, relevant public health information. For more information or to provide feedback on our services, please contact email@example.com.
