Is there any such thing as a non-self-spreading virus? Or, to re-phrase the question using some of the alternative, interchangeable, technical terms which pop up: is there any such thing as a non-transmissible, non-self-disseminating, non-contagious, non-horizontally-transferable virus?
The answer is no. Viruses only exist by hijacking living cells and forcing them to churn out viral particles. Viruses wouldn't exist if they weren't self-spreading, transmissible, self-disseminating, contagious, horizontally transferable (and uncontrollable).
So, what are we talking about?
