Etymology
the term 'poliovirus' is a modern scientific compound, directly combining greek and latin roots to describe the specific causative agent of poliomyelitis. the first element, 'polio-', is derived from the greek 'polios' (grey), a reference to the grey matter of the spinal cord which the disease inflames and damages. the second element, '-virus', comes from the latin word for 'poison' or 'slimy liquid', which in modern virology denotes a submicroscopic infectious agent. thus, the word's construction logically denotes the 'grey matter poison,' accurately reflecting the pathogen's target and its pathogenic nature.
Analysis

polio is from greek 'polios', meaning 'grey', referring to the grey matter of the spinal cord affected by the disease. virus is from latin 'virus', meaning 'poison, slimy liquid'.
Examples
the global effort to eradicate poliovirus has been largely successful through widespread vaccination.
the poliovirus is primarily transmitted through the fecal-oral route.
scientists study the structure of the poliovirus to develop more effective antiviral treatments.
