  1. Virulence is, by MeSH definition, the degree of pathogenicity within a group or species of parasites as indicated by case fatality rates and/or the ability of the organism to invade the tissues of the host. The pathogenicity of an organism - its ability to cause disease - is determined by its virulence factors. The noun virulence derives from the adjective virulent. Virulent can describe either disease severity or a pathogen's infectivity. The word virulent derives from the Latin word virulentus, meaning "a poisoned wound" or "full of poison.
  2. Virulence is a peer reviewed medical journal that covers microbiology and immunology specifically, microorganism pathogenicity, the infection process and host–pathogen interactions. It is published 8 times per year by Taylor & Francis. It was previously published 6 times per year by Landes Bioscience. The journal was established in 2010 by Eva M. Riedmann, and Eleftherios Mylonakis. The editor-in-chief is Eleftherios Mylonakis.
