swine flu

I've done my research and this is what i found out....Swine flu is also called hog flu and pig flu. Swine flu is common in swine in the Midwestern part of the United States. It is said that swine flu is rare in humans, but people who work with swine are at risk of catching swine influenza. The H1N1 form of swine flu is one of the descendants of the Spanish flu that caused a pandemic in humans from 1918-1919. The virus is constantly changing which avoids the protective antibodies that people have developed in response to the previous exposures that they have had. This new outbreak of swine flu is due to a new type of swine flu known as influenza A virus subtype H1N1 that comes from reassortment of one strain of human influenza virus. It is not known where the origins of this new strain come from but the World Organization for Animal Health reports that this strain isn’t just in swine. It can pass from human to human with ease because it is and unidentified mutation. Swine flu causes only mild symptoms and the person that is infected can make a full recovery without requiring medical attention and without the help of antiviral medicines....that was my extra credit for the anatomy quiz.
