Hep A
administer this within 2 weeks of exposure to Hep A if not previously vaccinated
immune globulin
administer for contacts to provide passive immunity
immunoglobulin

C
what test to confirm C
no specific
med management of C
antiviral agents. Combination of interferon and ribavirin
new meds for Hep C. Expensive

this requires hepatitis B surface antigen for its replication
D
these two cause super infection
B,D
fecal/oral route and resembles A. Abrupt onset.
