Dear AJK,
The viral replication in your liver has ceased so you are no longer infectious. By “previous” I mean that your infection is in the past. Your immune control will very effectively protect you from any possible future infection so there is no concern in this regard.
In very rare cases, reactivation of HBV infection can occur when persons who previously recovered from HBV infection take immunosuppressive therapies. This is why it will always important to mention to any doctor you see that you have recovered from HBV infection.
Hope this helps…
