Influenza is a highly contagious respiratory illness caused by influenza viruses. There are three main types of influenza virus that cause infection in humans - types A, B and C - and many sub-types or strains. Influenza can occur throughout the year but in NSW influenza activity usually peaks in winter.

Recommending influenza vaccination for patients and staff is an important preventive action, especially for people at increased risk of complications from influenza infection who are eligible for free vaccine. For more information on influenza vaccine recommendations and how to order free vaccine see the NSW Health Immunisation Program.
