What is “Swine Flu”?
Swine Flu is a type of influenza
Usually infects pigs
Human transmission from pigs has regularly but infrequently occurred over the years
Human-to-human has previously been rare
What is happening now? One type of swine flu, H1N1, has undergone a change into a new
virus subtype: Now has the ability to more easily spread from human to human
To avoid confusion: Swine Flu H1N1 is different from Human Flu H1N1

World Health Organization (WHO) Pandemic Phases
Phase 1: No cases of animal influenza virus in humans Phase 2: Human infection by animal influenza virus Phase 3: Sporadic cases or small clusters, but no sustained human-to-human spread (Current Level)
Phase 4: Sustained human-to-human spread in communities Media frenzy Minimal disruptions to business or clinical care
Phase 5: Sustained human-to-human spread in multiple countries within a global region
Localized disruptions Fear
Phase 6: Full Pandemic (eg, world) Multiple “waves” Healthcare system completely overwhelmed Social isolation strategies adopted and enforced Pharmacy supply chain disruptions Pharmacy and medical regulations liberalized Government use of emergency powers

When is “the flu” NOT the flu?
Symptoms of influenza are severe High fever Cough Sore throat Body aches Headache Extreme fatigue Occasional diarrhea or vomiting
Most respiratory infections are not the influenza (the flu), they are a cold
Symptoms may be similar to above, but are milder More likely to have a runny or stuffy nose
