Avian influenza

Avian influenza has now been found in a number of provinces across Canada, including Alberta. Avian influenza is caused by different virus strains than those that cause seasonal influenza in humans. An avian influenza outbreak in poultry does not mean that there will be a human outbreak or pandemic.

The risk to the public of catching the avian influenza virus is very low. People cannot be exposed to avian influenza through the consumption of properly cooked poultry or eggs because the virus is destroyed by cooking.

About influenza

Influenza – commonly referred to as the flu – is a respiratory disease caused by a virus that affects the nose, throat and lungs. Influenza is contagious and easily passed from person to person.

Influenza lowers the body’s ability to fight other infections, including COVID-19. It can lead to bacterial infections, such as pneumonia, and even death especially in the elderly, children (6 to 59 months), pregnant women, Indigenous people, and people with chronic medical conditions. Most healthy people recover from influenza without severe complications.

Various strains of the influenza virus circulate throughout the world each year and new strains can emerge and spread.

Seasonal influenza is the annual influenza that affects people in Canada during the winter, typically between November and April. While you can get influenza at any time, even in summer, it is most common in the colder months.

How to prevent influenza

The best ways to prevent seasonal influenza is by:

  • getting the influenza vaccine every year because the virus changes each year
  • washing your hands often

Antibiotics do not work against the influenza virus or any other virus. Antiviral medications may be used for treatment or prevention of influenza.

Vaccine effectiveness

Vaccine effectiveness varies from year to year but immunization is still the best protection. The effectiveness of the current vaccine is not known when the immunization program begins but is determined as the season progresses.

Influenza immunization during COVID-19

The influenza vaccine won’t prevent COVID-19, but it will reduce your chances of getting sick with influenza and spreading it to others. By keeping influenza counts low we can make sure our health-care system has capacity to respond to the COVID-19 pandemic and let health-care workers focus on treating people with other illnesses and injuries.

Get immunized

All Albertans 6 months of age and older can get the current 4-strain influenza vaccine free of charge by appointment at:

  • Pharmacies and doctors’ offices for people 5 years old or older
  • Some doctors will provide immunizations to children. Call your doctor’s office to find out more.
  • Alberta Health Services (AHS) public health clinics:
    • for children under 5, their parents and household members
    • for people without a provincial health care number
    • where there is no other immunizing health-care provider

Alberta residents aged 65 and older will have access to a high-dose vaccine free of charge.

Alberta has offered universal influenza immunization free of charge since 2009. Before 2009, the program targeted those most at risk of disease and complications.

Yearly influenza immunization rates

Every year we encourage more Albertans to get immunized.
