Does Hepatitis B have spontaneous viral clearance just like HCV?
Does Hepatitis B have spontaneous viral clearance just like HCV?
i was diagnosed with Acute HBV...what is the rate of which adults clear the virus on their own?
Have you been diagnosed with chronic or acute HBV? Do you understand the difference?
"Spontaneous Undetectable Hepatitis B Virus DNA Is Uncommon, especially without HBeAg Clearance
SUMMARY: Clearance of hepatitis B virus (HBV) DNA from the blood seldom occurs without treatment even after a decade, researchers reported at the 45th Annual Meeting of the European Association for the Study of the Liver (EASL 2010) last month in Vienna. Among people who experience hepatitis B "e" antigen (HBeAg) clearance, however, the likelihood of also achieving undetectable viral load was higher, approaching 50% at 10 years..."
"...."Spontaneous seroclearance of HBV DNA was a rare event, even after HBeAg seroclearance," the investigators concluded. "Lower baseline viral load and central obesity [were] associated with higher possibility of decreasing HBV DNA to undetectable level, whereas higher serum ALT level during follow-up associated with a lower possibility of HBV DNA decline."

A) The risk for chronic infection varies according to the age at infection and is greatest among young children. Approximately 90% of infants and 25%–50% of children aged 1–5 years will remain chronically infected with HBV. By contrast, approximately 95% of adults recover completely from HBV infection and do not become chronically infected.
