I would be happy to help as much as I can. I would first start with some good websites:
( you then have to look up Hep B)
I liked the info on those the best! There is also a yahoo group you can join for adoptive families it does have a lot of good info too. You can pm me if you want that link!
Hepatitis B has a vaccine out to prevent infection to family members. (Children in most states are required to have the vaccine for school entry.) Adults who would be at risk of getting exposure to the disease can also be vaccinated. Remember that you would need to take precautions if there is blood or body fluid exposure (not saliva or tears, we are talking semen or vaginal secretions). If there was an exposure there would need to be a point of entry on the person exposed as well to risk infecting that individual.
Your child would need to see a specialist regularly to monitor the viral activity. Some children need treatment and others might not.
If you have other specific questions you can let me know!!
Good luck and let us know if there is any news to share!!
