Hello,
thanks for using health care magic.
Hepatitis B is transmitted sexually and through direct contact with blood or blood products such as semen, plasma etc. According to WHO, the virus can stay out side the body for up to seven days and during this period transmission is possible if someone who has not been vaccinated against Hepatitis B to pick up the infection. Hepatitis B also can be transmitted by use of contaminated non sterilized metallic objects such as needles, blades or simply by coming in contact with contaminated blood.
Hepatitis B exist in both acute and chronic stages. In the chronic stage, a given marker of Hepatitis B known as Hepatitis B surface antigen remain positive for more than six months and it could remain positive for far beyond 6 months. This is the case for chronic carriers.
It is also possible to be infected with the virus and remain negative for Hepatitis B surface antigen in the initial stage of the infection.
So to partially answer your question,
Yes, there could be a fowl play,
Also, it could be that she came in contact with a contaminated blood
or she got infected through contaminated sharp objects like in the saloon,
or she got the infection long ago.
However, the above are based on the assumption that she is truly infected as you did not give the results of her test that said she was positive for Hepatitis B which could have been misinterpreted.
Let me know if you have more query.
