This article is about the influenza virus of 1918 and today. It bascially states that this virus has been around since then but has just mutated into other forms of the virus. The influenza virus of today is a descendent of the 1918 influenza virus. This article talks about the structure of the virus, it has eight genes, two of which code for the surface proteins. There also 16 H subtypes and 9 N subtypes which therefore allows the virus to make 144 different strains of this virus, but only 3 that they know of have been transmitted to humans. It also talks about how the virus is transferred from animal to human. They still dont have all the answers to how it transfers to humans, they are working on that. All we can do is stay cautious about our surroundings, dont touch our face after contact with someone sick, covering mouths when we cough, and last but not least wash your hands as often as you can.
