Colds and flu

Updated 04 October 2017

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 flu 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.
