  1. H1N1 Virus Grace Givens and Callie Chase

  2. What is it? • Subtype of the Influenza Virus • Respiratory virus that constantly changes • Mix of swine, human, and avian influenza

  3. 2009 H1N1 Pandemic • Outbreak of flu occurred in southern America along the border line of Mexico and in Europe • H1N1 was declared a national emergency by President Obama • First global pandemic since Hong Kong’s flu in 1968 • Over 20,000 deaths

  4. Cell Structure • RNA gene containing 8 RNAs • Roughly spherical, enveloped in a membrane that is taken from the host cell that it multiplies from • Beneath the membrane is matrix protein that provides support to the outer membrane • The interior contains the 8 RNAs, which are the genetic material of the virus • Has “spikes” attached to the membrane that it uses to latch onto the host cell, break open its wall, and inject its RNA into it

  5. Cell Structure (Continued)

  6. Symptoms • Difficulty breathing or shortness of breath • Pain or pressure in chest or abdomen • Sudden dizziness • Confusion • Severe or persistent vomiting • Flu-like symptoms improve then return with severe fever • Children develop a blue skin color

  7. How It Spreads • Spreads as a traditional flu would spread • Through coughing, sneezing, touching • Mainly caused by touching surfaces that infected people have • Immunity is hard to build up because of the constant mutation
