In order to avoid cross-infection with influenza and COVID-19, all people aged six months or above are suitable for vaccinating against seasonal influenza, except for those who are known to be contraindicated.

Understanding Seasonal Influenza

Seasonal influenza is mainly caused by four types of influenza viruses circulating in the community. It is an acute respiratory disease mainly transmitted through droplets. In Hong Kong, influenza is generally prevalent from January to March in winter and July and August in summer.

Symptoms of Seasonal Influenza

Influenza is more serious than cold

Influenza is different from cold. It is caused by different combinations of viruses. Generally speaking, the symptoms of influenza are more severe than those of the common cold. A cold usually does not lead to serious health problems such as pneumonia, bacterial infection, or hospitalization. Influenza, however, can result in very serious complications or mild to severe illnesses, and may even lead to death.

Influenza virus spreads easily

Seasonal influenza (virus) spreads more easily and rapidly in crowded places such as schools and nursing homes. When an infected person coughs or sneezes, the virus (which is contagious) travels through the air up to a metre away, spreading it to people who are in close proximity in the common space. In addition, influenza viruses can also be transmitted through infected secretions. To prevent infection, people should cover their mouth and nose with a tissue when coughing and wash their hands frequently. Getting a flu shot is an effective way to prevent flu and its complications!

* ‘Persons with chronic medical problems’ include patients who suffer from:

  1. Chronic cardiovascular diseases (except for those with hypertension but with no complications)
  2. Pulmonary diseases
  3. Metabolic or kidney diseases
  4. Obesity# (BMI is 30 or higher)
  5. Immunodeficiency^
  6. Children and adolescents (from 6 months to 18 years old) on chronic aspirin therapy
  7. Chronic neurological condition which could endanger their respiratory function, or make them difficult to handle respiratory secretions, or thereby increase the risk of aspiration
  8. People who lack the ability to care for themselves


# Obesity is considered as an independent risk factor for influenza complication and thus people with BMI 30 or above are included in the priority groups for seasonal influenza vaccination.

^ People who are immunocompromised refer to those with a weakened immune system due to disease (such as HIV/AIDS) or treatment (such as cancer treatment).

Members of the public can consult their family doctors to receive seasonal influenza vaccination for personal protection.
