Difference between Virulence and Pathogenicity?

[nukeman]

Greetings,

I have read several text regarding this, but I still can't manage do discriminate between them. So far what I've got is: Pathogenicity = The potential/ability of a infectious agent to cause damage. Virulence = The actual level of damage caused.

Is this correct or am I mistaken?

I'd say that pathogenicity is the ability to infect host, not damage
