What is seasonal influenza and flu shot?

Influenza is an acute illness of the respiratory tract caused by influenza viruses. 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. Influenza occurs in Hong Kong throughout the year, but is usually more common in periods from January to March/April and from July to August.

Symptoms of seasonal influenza

The virus mainly spreads by respiratory droplets. The disease is characterised by fever, sore throat, cough, runny nose, headache, muscle aches and general tiredness. It is usually self-limiting with recovery in two to seven days. However, if persons with weakened immunity and elderly persons get infected, it can be a serious illness and may be complicated by bronchitis, pneumonia, encephalopathy, or even death in the most serious cases. Serious infection or complications can also occur in healthy individuals.

The Scientific Committee on Vaccine-Preventable Diseases recommends the following priority groups for seasonal influenza vaccination in Hong Kong:

• Those who have experienced a severe allergic reaction to any component of the vaccine or to a previous influenza vaccination.

• Individuals with egg allergies should consult a doctor before vaccination.

• Patients with bleeding disorders or those taking anticoagulant medications should seek medical advice.
