H1N1 Virus
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
1968
• 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

constant mutation
