A virus enters your body through your nose, mouth, or a small break in your skin. Once the virus is inside, it attacks your cells one at a time. It takes control over a cell and makes the cell produce more of the virus. A few hours, days, or even years later, that cell explodes with hundreds of new viruses. These new viruses attack the cells around them. They make those cells produce even more viruses. As these viruses take over more and more cells, you begin to feel sick.
