Influenza, commonly known as “the flu” is a serious, acute respiratory illness that can lead to pneumonia. It is caused by a virus, and different strains of the influenza virus circulate each flu season. It’s important to get your flu shot every year so you’re protected with the vaccine designed to match the virus strains that are currently active.
The flu vaccine is provided free of charge each year to Ontario residents and is available through your family doctor or at any Health Unit Immunization Clinic.
Symptoms usually start 1 to 4 days after exposure to the virus. In most adults, the flu lasts 2-10 days. It sometimes lasts longer for the elderly, children and people with chronic illnesses.
You may have the flu if you experience:
- runny eyes
- stuffy nose
- sore throat
- muscle aches
- extreme weakness and tiredness
Symptoms vary from person to person, and some may last for several weeks. The elderly may not have a fever, while children can have symptoms like earaches or stomach problems.
