Flu - FAQ

You are in: Health24 : Medical : Condition centres : Flu > FAQ

Do I have the flu?
The onset of flu is usually very sudden - one can often pinpoint the exact hour when you start feeling ill. The incubation period from exposure to the virus to onset of symptoms is 1- 4 days, the symptoms last another 3 -4 days. Symptoms include a sudden onset of fever and chills, aching muscles, a dry cough, headache, fatigue and sometimes a sore throat or runny nose.

Flu spread?
An infected person sheds mucus from their nose and throat and the virus is aerosolised by speaking, sneezing and coughing.

Over-the-counter medication?

Over-the-counter drugs treat symptoms of flu, but not the cause. They will not cure flu, but will relieve some symptoms.

Should I have the flu injection?
People in the high-risk group should get the flu vaccine, and the vaccine is recommended for any adult or child older than six months.

What is the difference between flu and a cold?

This can sometimes be confusing. Both are viral infections and both can affect the nose and the throat.
Flu, however, is usually accompanied by a high fever and muscle aches and pains and a dry cough, which distinguishes it from a normal cold.
See the difference in symptoms of colds and flu.

What must I do if I get the flu?
Stay in bed and get lots of rest. Flu continues to be contagious for 3-4 days after the symptoms have appeared, so going to work or school is not a good idea.

Should I visit my doctor?
You should always visit your doctor when you feel seriously ill. If you fall into one of the risk groups mentioned above, it is also advisable, whether your symptoms are severe or not, as you could easily develop flu complications such as pneumonia, bronchitis, sinusitis or ear infection.
Anyone who has developed a high fever should see a health professional.
