​Public Health Ontario Laboratory Respiratory Pathogen Surveillance Reports

The Public Health Ontario Laboratory-Based Respiratory Pathogen Surveillance Report summarizes patients’ specimens tested at the Public Health Ontario Laboratories (PHOL) for influenza and other respiratory pathogens.

PHOL performs the majority of testing for influenza (the flu) and other respiratory viruses, but other microbiology laboratories also perform these tests. Therefore, it is important to note that the numbers reported here do not represent the total number of respiratory viruses identified in Ontario. Each report provides a summary from the current week and cumulative results for the entire season.

For a more comprehensive report, combining PHOL data and other sources of respiratory virus  testing data, please see the Ontario Respiratory Pathogen Bulletin, available at www.publichealthontario.ca/ORPB
