The Silent Enemy: Unraveling the Socioeconomic Consequences of Influenza in Australia and the Solutions Offered by Zali Health

Influenza, commonly known as the flu, is a highly contagious respiratory infection caused by the influenza virus. It affects millions of people worldwide each year, including thousands of Australians. This overview will delve deeper into the age groups most impacted by influenza in Australia, the cause and effect of the virus, and the role Zali Health plays in providing a various vaccination approach to protect Australians from the flu.

I. Age Groups Most Affected by Influenza in Australia

Influenza affects people of all ages, but certain age groups are more susceptible to complications and severe illness. According to the Australian Institute of Health and Welfare (AIHW), these age groups are:

  • Children under 5 years old: Young children, particularly those under 2 years, have a higher risk of developing severe complications from the flu, such as pneumonia or bronchiolitis. This is primarily due to their underdeveloped immune systems, which have not yet fully developed the ability to fend off the virus effectively.
  • Adults over 65 years old: The elderly are more vulnerable due to a weakened immune system that comes with age, which makes it harder for them to fight off the virus. Additionally, older adults often have pre-existing health conditions that can exacerbate flu-related complications.
  • Pregnant women: Pregnant women have a higher risk of developing severe flu-related complications, such as preterm labor and low birth weight, which can also affect the health of their unborn babies. This increased risk is attributed to the changes in their immune system, heart, and lungs during pregnancy.

Annual influenza cases: Approximately 70,000 – 170,000

Hospitalisations: 13,000 – 27,000

Deaths: 250 – 3,500

II. Cause and Effect of Influenza

Influenza viruses are classified into four types: A, B, C, and D. Influenza A and B viruses are responsible for the seasonal epidemics experienced in Australia. The virus spreads through respiratory droplets when an infected person coughs, sneezes, or talks. It can also spread by touching contaminated surfaces and then touching the mouth, nose, or eyes. The virus enters the body and attacks the respiratory system, causing a range of symptoms such as fever, cough, sore throat, muscle aches, and fatigue.

The effects of influenza can range from mild to severe, and in some cases, can be life-threatening. Complications can include pneumonia, bronchitis, sinus infections, and ear infections. In some instances, the flu can worsen pre-existing chronic health conditions, such as asthma or heart disease. The economic impact of influenza in Australia is also significant, with the total cost of the flu estimated to be around $3 billion annually, including healthcare expenses and productivity losses.

III. Zali Health’s Vaccination Approach

Vaccination is the most effective way to prevent influenza and its complications. Zali Health is committed to providing vaccination services to protect Australians from the flu. Their approach includes:
