4. Facts About Viruses They DO NOT eat or grow
They DO NOT do any chemical process
They DO NOT respond to light or stimuli
Antibiotics DO NOT work on Virus; there is no drug to cure any virus

5. More Facts about Viruses
They are smaller than bacteria, plant and animal cells
They come in thousands of shapes
They replicate using the lytic and lysogenic cycle
They are able to infect organisms through carriers, air, touch and vectors
Vaccines can prevent some virus from infecting

6. Even more Facts about Viruses
Viruses invade a host and replicate and kill the host’s cells
A carrier is an infected person-can show the signs of the disease or not for example HIV infected person
A vector is an organism (except for humans) that can spread a disease for example:
Tick-Rocky Mountain Spotted Fever and Lyme's Disease
Mosquito- West Nile Virus and Malaria
Flea-Black Plague
