WebFeb 4, 2024 · Viruses are bits of genetic information, either RNA or DNA, surrounded by protein. A virus needs a living host, such as a person, plant or animal. To spread, a virus gets into a host's body and then into the host's cells. Then it takes over the host cell's machinery, using it to make more of the virus. Diseases caused by viruses include:
