Overall Summary

  • Influenza activity in Canada remains at expected levels for this time of year with very few laboratory detections of influenza.
  • Other respiratory virus detections (RSV, coronavirus, and human metapneumovirus) are also at expected levels. Detections of parainfluenza and adenovirus have decreased in this reporting period.
  • In week 34, two influenza outbreaks were reported.
  • As of week 34, 5,457 hospitalizations and 344 deaths have been reported from participating regions, which is more hospitalizations but a similar number of deaths than were reported last year.

Note: This is the final report for the 2013-2014 influenza season. The first FluWatch report of the 2014-2015 influenza season will be published on September 12, 2014. Alternate week reporting will continue until October 10, 2014 when weekly reporting will resume. Laboratory detections reported through the Respiratory Virus Detection Surveillance System and influenza activity level maps continue to be updated weekly on the FluWatch website.

About FluWatch

FluWatch is Canada's national surveillance system that monitors the spread of flu and flu-like illnesses on an on-going basis. FluWatch reports, posted every Friday, contain specific information for health professionals on flu viruses circulating in Canada.

The FluWatch program consists of a network of labs, hospitals, doctor's offices and provincial and territorial ministries of health. Program objectives include to:

  • Detect flu outbreaks across the country as early as possible
  • Provide timely up-to-date information on flu activity in Canada and abroad to health professionals [and interested Canadians]
  • Monitor circulating strains of the flu virus (like H1N1) and assess their sensitivity to antiviral medications, [such as Tamiflu and Relenza]. Antivirals, when used by doctors to treat flu, can help reduce the severity of the illness and the recovery time for a patient
  • Provide information that the World Health Organization can use to make its recommendations on the best vaccine to use for seasonal flu shots.

The Summary Box above covers the main findings from the current week's FluWatch report.
