Although many viruses are classified into individual families based on a variety of physical and biological criteria, they may also be placed in groups according to the type of genome in the virion. Over 30 years ago virologist David Baltimore devised an alternative classification scheme that takes into account the nature of the viral nucleic …

For the first 60 years of virus discovery, there was no system for classifying viruses. Consequently viruses were named haphazardly, a practice that continues today. Vertebrate viruses may be named according to the associated diseases (poliovirus, rabies), the type of disease caused (murine leukemia virus), or the sites in the body affected or from which …
Since Monday I have been in Sitges, Spain for Europic 2008. This is a scientific meeting on picornaviruses held every other year in a European country. The picornaviruses are a family of non-enveloped, positive-strand RNA viruses, and includes poliovirus, rhinovirus, and foot-and-mouth disease virus. I have been attending Europic meetings since 1983, when it was …
