Viruses

What is a virus? microscopic, nonliving particle Invades and then reproduces inside a living cell.

Characteristics Virus are not living. Shapes: rod, round, spikey

How viruses multiply Attaches to a cell Injects DNA into cell Takes over cell parts Makes copies using cell parts Breaks open the cell (cell dies) Repeats on other cells Step-by-Step: Virus Attacking Cell

Viral Diseases AIDS Chicken pox Influenza

Viral Diseases Measles Polio Rabies

Treatment for viruses No medications can cure viral infections. Over-the-counter medications can treat symptoms.

Preventing Viruses Vaccine – prevents spread of some viral diseases. Made from a dead or weakened virus. This helps the body recognize the live virus when it comes in. Now it will be ready to attack it before it makes you sick.
