Detailed explanation-1: -This subsection of the Names and taxonomy section only exists in viral entries and indicates the host(s) either as a specific organism or taxonomic group of organisms that are susceptible to be infected by a virus.

Detailed explanation-2: -Indeed, viruses have the remarkable ability to spread from one host to another host, hosts that belong to the three cellular domains of life-Archaea, Bacteria, and Eukarya. This constitutes their host range.

Detailed explanation-3: -A virus is a tiny, infectious particle that can reproduce only by infecting a host cell. Viruses “commandeer” the host cell and use its resources to make more viruses, basically reprogramming it to become a virus factory. Because they can’t reproduce by themselves (without a host), viruses are not considered living.

Detailed explanation-4: -One or several virus-encoded glycoproteins are inserted into the envelope. These proteins are exposed at the virion surface and are responsible therefore of the initial interactions of the virus with the target cell, leading to “virus entry”.
