My partner had hepatitis a before, his doctor said that he is not contagious now since he already survived it. am i still at risk to got it?

Nope: Hepatitis A, unlike hepatitis B and C, does not cause a chronic illness. It is like most other viruses where it causes a self limited disease: the end of which either you survive it or succumb to the acute illness/liver failure. So if a person has survived it in the past, they will no longer have any active virus to pass on. Hope this helps.

No danger to you.: Hepatitis A is a predominantly acute gastrointestinal illness that is obtained/transmitted through fecal matter and contaminated food/water sources. Once you have had hepatitis A, you might be sick for ~ 3-4 weeks afterwards but then retain immunity for life. Blood testing will continue to show past exposure to Hep A, but there is no future danger for the patient or any future partners.
