flu+questioms+homework

The flu is very serious because it is a virus. THink of it as a super cold, in which by the time it reaches you it has mutated several times to adapt into a cold that can't be cured easily. Once you have it, then its to late to get the shot, and you have to just wait it out. If you get the shot before you are infected then you can prevent it from occuring in your body. It is sprezd through animals, and mainly ones that humans comsume. It is also transmitted through coffs ans sneezes, so it is widly considered to be an airbourn virus that can easliy be attained by people. Infected chickens and birds are usuially the first to get the disease, and then it spreads from person to person once they are infected. The benifits are not getting the flu or any of its symptoms. The downside is that you have to get a shot (YIKES) and you arm can get sore for a couple of weeks
