- This article is about a biological infectious particle; for the computer term, see computer virus. For other uses, see virus (disambiguation).
A virus (Latin, poison) is a submicroscopic particle that can infect the cells of a biological organism. At the most basic level viruses consist of genetic material contained within a protective protein shell called a capsid, which distinguishes them from other virus-like particles such as prions and viroids. The study of viruses is known as virology, and those who study viruses are called virologists.
Viruses are similar to obligate intracellular parasites as they lack the means for self-reproduction outside a host cell, but unlike parasites, which are living organisms, viruses are not truly alive. They infect a wide variety of organisms, both eukaryotes (such as animals and plants) and prokaryotes (such as bacteria). A virus infecting bacteria is known as a bacteriophage, which is used mainly in its shortened form phage.
