Published: Thursday, 20 April, 2017 - 16:21

Influenza Surveillance data is collected all year round by the Public Health Agency in collaboration with the Northern Ireland Regional Virus Laboratory, local GP practices, and a number of other relevant local agencies who kindly provide data to the influenza surveillance department.

The earliest occurrence of seasonal influenza varies from year to year; but most often occurs during the winter months - usually beginning in October or November, and peaking between December and March. During the ‘flu season the PHA publishes a regular ‘flu bulletin outlining the season so far, including GP consultation rates and information on the circulating virus.
