Overview • FLU FACTS: To understand the difference between the terms seasonal, avian and pandemic influenza, and the impact of a pandemic • FLU PREP: To identify ways that NJ is preparing for an influenza pandemic • FLU & YOU: To identify steps people can take to protect themselves
What is Influenza? • Primarily infection of upper respiratory tract • Incubation period: 1-3 days • Infectious period: 24 hours before symptom onset and up to 5 days after symptom onset
What causes Influenza?Three types of influenza viruses: A, B & C • Type A • Can infect humans and other animals • 144 potential strains (H-16; N-9) • Wild birds are the natural reservoir • Most likely to cause epidemics and pandemics (cont.)
Types of Influenza • Type B • Humans only • No subtypes • Can cause epidemics, not pandemics • Type C • Humans and swine • No subtypes • Mild illness; does not cause epidemics
Seasonal Influenza in the US • Occurs annually – October through April • More than 36,000 deaths • More than 200,000 hospitalizations • Elderly, young children and people with certain health conditions are most vulnerable • Largely preventable through vaccine
Prevention & Treatment • Prevention • Annual flu vaccination • Respiratory hygiene • Social distancing • Treatment • Fluids, fever reducing medication, bed rest • Antiviral medication – not a cure!
Why a flu shot each year? • Drift (Types A and B) • Minor change, within subtype • Gradual accumulation of amino acid changes in HA and/or NA • May cause epidemic • Example: drifted A/H3N2/Fujian circulated A/H3N2/Panama (vaccine strain 2003/4) Occurs continuously • Shift (Type A only) • Major changes new subtype • Exchange of gene segments • May cause pandemic • Example: H3N2 replaced H2N2 in 1968 Occurs infrequently Cox NJ, Subbarao K. Lancet 1999;354:1277-82
What about Avian Influenza? • AKA: Bird Flu • Type A, H5N1 • Carried by migratory waterfowl • Virus passed to domestic poultry • Direct transmission to humans from poultry • High death rate
What is a pandemic? • Epidemic = community or regional outbreak of an infectious disease • Pandemic = global epidemic
What causes a Flu Pandemic? • New strain of virus • Ability to cause serious disease and death in humans • Easy person-to-person spread
Challenges • Health Care • Social • Personal
Health Care Challenges • Don’t know which people the virus will affect the most • Vaccines will not be available in the early stages of pandemic • Antivirals, if available, may be ineffective • Health care workforce will be sick along with everyone else • Health care system will be overwhelmed
Societal Challenges • Maintaining essential government services and business • Implementing social distancing • Distributing limited amounts of medications and vaccines • Maintaining civil order
Personal Challenges • Protecting self and family • Attending school/work • Obtaining goods, services and necessities • Maintaining daily life activities • Obtaining medical care • Traveling • Obtaining reliable information
Governmental Preparedness • The Centers for Disease Control & Prevention and the US Dept. of Human Services • NJ Dept. of Health & Senior Services and the Office of Homeland Security & Preparedness • Local and regional health depts. • www.njmrc.nj.gov
Healthcare System Preparedness • Developing preparedness plans • Enhancing infection control procedures • Stockpiling supplies • Cross training staff • Conducting exercises
Personal Preparedness • Keep a supply of food, water and medical supplies • Start now to develop healthy habits • Respiratory hygiene • Hand hygiene • Stay home if sick • Know where to get reliable health information • Follow instructions provided by governmental public health authorities
Summary • Flu pandemics are unpredictable • We don’t know if the avian H5N1 virus will cause the next flu pandemic • Flu pandemics can have serious impact on us, society, businesses and the health care system • NJ governmental agencies are preparing for a potential flu pandemic
