What is the difference between a viral and a bacterial infection?

Both viral and bacterial infections will make you feel sick and they share many of the same symptoms. But, did you know that:

• a cold or flu virus usually lasts only up to 10 days while illnesses caused by bacteria usually last more than two weeks?
• cold and flu symptoms - runny noses, watery eyes, dry coughs, sore throats, chills, aches and pains - are caused by viruses, not bacteria?
• adults who have a sore throat without significant fever most likely do not have a bacterial infection, such as strep throat? - their disease is more likely to be caused by a virus.
• most coughs do not need an antibiotic?

REMEMBER - If your symptoms suggest a viral infection, antibiotics won't help. Your doctor or pharmacist will be able to recommend medications to help you feel better while the virus runs its course.

Do I have a bacterial infection?

The following signs and symptoms, usually lasting longer than two weeks, suggest a bacterial infection:

• a high, persistent temperature
• a thick, coloured discharge from your nose
• a chronic cough

REMEMBER - Antibiotics should only be used when they are truly needed - to cure a bacterial infection.
