Emergence and immergence of viruses

Viruses have an extremely long history and they are extremely widely spread in the planet. They are the simplest biological organisms which consist of genetic information and mechanisms to transfer this information into host for multiplication. It is therefore a natural way to comprehend virus as a piece of information. Viruses are highly dependent on their hosts and utilize their life cycles. In viral life cycle, it is essential that new susceptible individuals need to become infectious. For this purpose, viruses have evolved to utilize different routes of transmission and survival mechanisms. In this article the mechanisms for emergence and immergence of the most significant virus types are analyzed according to Boolean logic analysis in order to provide new insights for how we perceive emergence.
