acute phase
past exposure
you are way more likely to get this disease than HIV from a needle stick
Hep B
Risk of Chronic Infection After Acute Exposure is highest in
newborns of HepBeAg+ mothers
Actively replicating virus in the body (HBeAg), if mother has this then newborns are very likely to get chronic hep B
this is used to monitor antiviral therapy for Hep B
HBV DNA
this is the main test for Hep B and earliest indicator of acute Hep B infection
HBsAg
Response to surface antigen, this means you cleared it or have immunity
HBsAb or anti-HBsAg
Hep B virus is replicating and very infectious
HBeAg
Hep D requires
Hep B, treat Hep B and D will go away
Negative RNA indicates recovery
progression to chronic hep B is shown when
HBsAg is present forever
