Viruses can exist in two states. The virus is completely inactive when it is not in contact with a host cell. There is no internal biological activity occurring within the virus at this time, and the virus is effectively reduced to a static organic particle. Viruses are called virions in this simple, clearly non-living stage. Virions can stay in this inactive form for long periods, patiently waiting for the right host to come along. When a virion comes into contact with the right host, it becomes active and is labelled as a virus. It now exhibits characteristics that are characteristic of living organisms, such as reacting to its surroundings and focusing its efforts on self-replication.
