Influenza is an infectious viral disease. It can be caused by various types of influenza viruses. In Hong Kong, the two subtypes of influenza A virus, H1N1 and H3N2, and influenza B virus, are most commonly seen. The virus mainly spreads by respiratory droplets.

The circulating seasonal influenza strains may change from time to time. In accordance with the circulating strains, the seasonal influenza vaccine composition is updated every year to enhance protection. Therefore, it is necessary to get vaccinated against seasonal influenza every year. Immunity to influenza begins approximately 2 weeks after having the shot.
