2. What is a Virus?

A virus is a microscopic organism that may cause mild to severe illness in humans. Virus organisms are 100 times smaller than a single bacteria cell, which is itself 100 times smaller than the diameter of a human hair. A virus is not a living organism; it multiplies by entering a human, animal, or bacterial cell; it takes control of the cell by inserting genetic material into the cellular cavity. The occupied cell produces virus particles instead of healthy cell components. These particles combine to create more viruses, which escape the cells and repeat the process.
