Influenza or flu is a highly contagious viral infection that can cause severe illness and life-threatening complications, including pneumonia. The flu is spread by contact with fluids from coughs and sneezes.
The most common symptoms of the flu are:
- sudden appearance of a high fever (38 °C or more)
- a dry cough
- body aches (especially in the head, lower back and legs)
- feeling extremely weak and tired
Symptoms of influenza hit very quickly and may last for several weeks. A bout of the flu typically follows this pattern:
- Days 1–3: Sudden appearance of fever, headache, muscle pain and weakness, dry cough, sore throat and sometimes a stuffy nose.
- Day 4: Fever and muscle aches decrease. Hoarse, dry or sore throat, cough and possible mild chest discomfort become more noticeable. You may feel tired or flat.
- Day 8: Symptoms decrease. Cough and tiredness may last one to two weeks or more.
How can i Avoid the Flu
Annual immunisation against the flu is recommended for all people from six months of age. Many people in the above groups are eligible for free flu vaccination each year (in autumn) under the National Immunisation Program. Anyone in these at-risk groups with flu-like symptoms should see their doctor as soon as possible.
See your doctor if you are concerned, and seek immediate medical attention if you experience any of the following symptoms:
- difficulty breathing
- chest pain
- sudden dizziness
- severe vomiting
- fever with a rash.
What medications should I take for the flu?
The flu is a viral infection so antibiotics won’t help at all and should not be taken.
Decongestants and simple pain relievers can help you feel better while your body’s immune system fights off the infection.
Follow these tips for buying over-the-counter medication for the flu:
- Buy a remedy that treats only one symptom; this way you are not taking in substances that you do not need, or that may trigger an adverse reaction.
The best things you can do to look after yourself when you have the flu are:
- Rest – you will probably feel very weak and tired until your temperature returns to normal (about three days), and resting will provide comfort and allow your body to use its energy to fight the infection
- Stay at home – stay away from work or school and avoid contact with others as much as possible while the infection is contagious. The period during which adults are contagious is usually around 3–5 days from when the first symptoms appear, and up to 7 days in younger children.
- Drink plenty of fluids – extra fluids are needed to replace those lost because of the fever (through sweating). If your urine is dark, you need to drink more. Try to drink a glass of fluids, such as water, every hour while you are awake.
