Infectious diseases are caused by pathogenic microorganisms, such as bacteria, viruses, parasites or fungi; the diseases can be spread, directly or indirectly, from one person to another.
Among the more common are influenza, the common cold, mononucleosis, and tuberculosis.
Influenza is an infection of the lungs and airways caused by a virus. It usually affects people in Alberta from November until April. You can protect yourself and keep it from spreading by taking some precautions.
To limit the spread of germs and prevent infection:
- Wash your hands often, using plenty of soap and warm water. If that's not possible, use alcohol-based sanitizer liquids.
- Cover coughs and sneezes with tissues. Or if necessary, cough into your sleeve.
- Stay away from others as much as possible when sick.
- Stay home from work and school if you become sick.
- Get an annual flu shot.
- Get plenty of rest and strive to stay healthy with proper nutrition and exercise.
