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 …

Recently while driving north on the New York State Thruway I passed the exit for the town of Coxsackie, NY (population 8,884). I grabbed my camera and photographed the exit sign, and reminded myself to write about the virus named after this small town. In the summer of 1947 there were several small outbreaks of …
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 …
Marburg virus has been isolated from Egyptian fruit bats (Rousettus aegyptiacus) living in Kitaka Cave, Uganda, demonstrating that bats are a natural reservoir of the virus. Marburg virus, the founding member of the Filoviridae, is an enveloped virus with a negative-strand RNA genome. Other members of the filovirus family are the five species of ebolavirus. Filoviruses …
The Centers for Disease Control and Prevention (CDC) would like to know what the public feels about the impending H1N1 influenza vaccination program this fall. The agency plans to conduct ten meetings in different parts of the United States to learn if the public would like a massive vaccination campaign, or a reduced effort. The meetings …

A few weeks ago I asked readers to find the errors in the following statement concerning an experimental influenza vaccine produced by Protein Sciences which involves synthesis of the viral HA protein in insect cells. They warned that the virus could mutate during the southern hemisphere’s flu season before returning north in a more lethal form …
