What Are Viruses?
Viruses have been hitting the headlines a lot recently. A virus is simply a tiny submicroscopic viral agent that replicates within the living cells of a living organism. Viruses can infect all forms of living organisms, from plants and animals to humans and microorganisms, such as bacteria. They can also invade the living tissues of other organisms through a process called infection, where they replicate and spread throughout the body.
