A virus does not possesses the tendency to reproduce outside the host cell, as they are devoid of the needed cellular machinery. Thus, it invades and combines itself with a particular host cell, administers its genetic substance, and proliferates by utilizing the genetic substance of the host, and thus, create new viruses within the host.
