Grace Givens and Callie Chase
What is it?
• Subtype of the Influenza Virus
• Respiratory virus that constantly changes
• Mix of swine, human, and avian influenza
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
• Over 20,000 deaths
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
Cell Structure (Continued)
Difficulty breathing or shortness of breath
Pain or pressure in chest or abdomen
Sudden dizziness
Severe or persistent vomiting
Flu-like symptoms improve then return with severe fever
Children develop a blue skin color
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
