  1. Infection...

  2. Our ViIlain.

  3. There are three main types of Influenza Viruses. (many strains) • Type A • Type B • Type C – Not clinically important in humans. • The variation in viruses is based on the surface antigens. • Hemagglutinin (H) • Neuraminidase (N)

  4. In Australia • 85 deaths, 4250 hospitalisations (reported) • 2000 deaths, 10000 (computer model)

  5. Spread of Disease Do you know how the Influenza virus is spread?

  6. Who will be infected??

  7. Impact on our systems How does influenza impact our body systems?

  8. Wide spectrum of disease. • Respiratory illness with systemic features: • Coughing, Sneezing, Shortness of Breath, Rapid Breathing, Chest Pain • Multisystem effects: • Confusion, Dizziness, Vomiting, Muscle aches, Fatigue, Nausea, Diarrhoea • Secondary Infections: • Bacterial Pneumonia

  9. Our Body’s battle!!

  10. What could have been done?? Is there something we could have done to try and combat this spread? Minimise our Exposure?

  11. Vaccines

  12. How do they work? • Improves immunity through: • Providing an antigen that either matches a pathogen or resembles it. • Allows for body to have a primary response and develop specific antibodies. • There are 7 types of vaccines: • Inactivated, Attenuated, Toxoid, Subunit, Conjugate, Experimental and Valence

  13. How well do they work? • Most adults: • Develop a high concentration of Antibodies • Protect against the specific strain of Virus • Can be protected against many related variants • Young, Elderly and Immune Dificient • Develop low concentrations of Antibodies • Vaccine may be more effective at preventing certain regions being involved or complications.

  14. Efficacy is based on: • The Disease itself • The strain of Vaccine • Vaccination Schedule • Non-responders • Other factors such as Ethnicity, Age or genetic predisposition.

  15. Flu Vaccines • Fluad, Fluarix, Fluvax, Fluvirin, Influvac, Vaxigrip and Vaxigrip Junior • All have a 0.5ml Dosage which contains 15µg of the 3 recommended strains of the season. • Split Virion or Subunit Vaccines • Prepared from inactivated Influenza virus • Cultivated in embryonated hens’ eggs.

  16. Our story.... • One student was infected by a strain of the Influenza Virus • Within 5 Minutes most of the students in the class were infected. • The virus could have varying impacts on your body systems • Our body tried to fight it and develop immunity • We may have been able to assist our body with some pre-planning - Vaccines
