Blog 1: Virology is the branch of science that deals with the study of viruses. It may sound bland and simple but there is a lot more to it then you think. There are many many types of viruses and all of them can result in a multitude of different sicknesses or diseases. It starts of by a virus entering the body through a wound or an open passageway like the mouth. This leads to that virus infecting one cell in the body. When the cell is infected the virus put its DNA in the cell to tell it what to do. After the cell has been infected it start to multiply very quickly. The virus can not muliple in the body unless it has a host (cell). A virus can multiply really fast and spread far across the body. This is why you get sick. One single virus can not get you sick by itself but when it multiples it can. A virus can cause a lot of sicknesses such as the common cold, the flu, chicken pox, ebola, and lots more. A virus can give you a simple sickness like a normal cold or a very dangerous one like ebola that can spread around an area faster than the blink of an eye. Viruses can take genetics from one host to another, even if they are not related. http://www.news-medical.net/health/What-is-a-Virus.aspx http://www.ucmp.berkeley.edu/alllife/virus.html
