I realize I’m weighing in late since I just joined the list, but have you been diagnosed with chronic hepatitis B? Or is it possible that this is a new infection and you could still get rid of the virus? 90% of adults who are infected are able to clear the virus after 3-6 months. So it’s important to get tested again before assuming you have chronic hepatitis B (unless the clinic definitely said you have “chronic” hepatitis B). If you have your lab tests and are willing to post them, we could help figure out whether you have a new or chronic infection.
If you know it’s a chronic infection (meaning you test positive for HBV again after 6 months), I agree with Thomas that you may never know exactly how you were infected with HBV. If you were born outside the U.S., it could be that your mother unknowingly transmitted the virus when you were born (called maternal to child transmission). This is the most common route of transmission outside the U.S. because women are not tested for HBV before giving birth (in the U.S. all pregnant women are tested for HBV before delivering so their baby can get the first dose of the HBV vaccine within the first 12 hours of life). However, if you were born in the U.S., you could have gotten the HBV from a sexual partner or even as a young child (playground bloody scrape, etc.), maybe even from a dental or medical procedure (most unlikely but not out of the realm of possibilities).
Again, sorry I’m entering the conversation so late, but hopefully you are feeling calmer and have a better understanding of your situation? Thanks, Joan
