Seasonal influenza is more than just a common cold. It often develops suddenly and may lead to serious complications. Vaccination and good personal hygiene can help protect you and your family.

Know the Symptoms

Common symptoms include sudden fever, cough, sore throat, muscle and joint pain, and severe tiredness. Some people may also experience vomiting or diarrhoea. The virus mainly spreads through respiratory droplets and contact with contaminated surfaces.

Who Is at Higher Risk?

The following groups are more likely to develop serious complications:

Infants and children

Older adults

Pregnant women

People with chronic illnesses

People with weakened immune systems

Residents and carers of residential care homes

Why Get Vaccinated Every Year?

Influenza viruses change over time, and protection from vaccination gradually decreases. Annual vaccination helps reduce the risk of severe illness, complications and hospitalisation. It usually takes about two weeks for the body to develop sufficient protection, so early vaccination is recommended.

Vaccination Guide

Seasonal influenza vaccination is generally recommended annually for people aged six months or above. Some children under nine years old may require two doses, depending on their vaccination history and the vaccine used. Please consult a healthcare professional for the appropriate vaccination schedule.

6 Ways to Prevent Seasonal Flu

Wash your hands regularly

Cover your mouth and nose when coughing or sneezing

Avoid touching your eyes, nose and mouth with unwashed hands

Keep indoor areas well ventilated

Stay home and wear a mask if you have respiratory symptoms

Maintain a balanced diet, regular exercise and sufficient sleep

Know When to Seek Medical Attention

Seek medical advice promptly if you experience difficulty breathing, chest pain, persistent high fever, confusion, severe vomiting, difficulty eating or drinking, significantly reduced urination, or a sudden worsening of symptoms after initial improvement.

Prevention is better than cure. Get vaccinated early and maintain good hygiene to protect yourself and those around you.
