There is currently no legislation or case law obliging patients to tell their doctors, nurses, dentists, surgeons, paramedics or any other health professionals that they are HIV-positive. This means that whether or not you decide to disclose your HIV status to your doctor (or any other health-care professional) is up to you. Your personal health information, including your HIV status, is private, personal information.
