They are looking for a host organism to infect so that they can use the machinery in the cell to multiply and create more viruses. Viruses are choosy about what they infect; plant viruses will only plants, some viruses only infect bacteria whilst others infect animals.
Introduction to viruses. A virus is a biological agent that reproduces inside the cells of living hosts. When infected by a virus, a host cell is forced to produce thousands of identical copies of the original virus at an extraordinary rate. Unlike most living things, viruses do not have cells that divide; new viruses are assembled in the infected host cell. But unlike still simpler infectious agents, viruses contain genes, which gives them the ability to mutate and evolve. Over 5,000 species of viruses have been discov
