http://www.cdc.gov/ncidod/diseases/hepatitis/b/fact.htm I especially like the un-well written parts of:
"Men who have sex with men."
and personal favorite:
"Do not shoot drugs; if you shoot drugs, stop and get into a treatment program; if you can't stop, never share drugs, needles, syringes, water, or "works", and get vaccinated against hepatitis A and B."
yum.
