What are viruse
A virus is a submicroscopic infectious agent that replicates only inside the living cells of an organism
What is important about them?
The importance of a virus is not due to the virus itself, but to the hosts they infect and affect, and many viruses are important because they cause diseases in humans, animals, or crops.
Are they of any use to us
Some viruses we come across protect humans against infection by other pathogenic viruses. For example, latent (non-symptomatic) herpes viruses can help human natural killer cells (a specific type of white blood cell) identify cancer cells and cells infected by other pathogenic viruses.
