Mississippi Code Title 41. Public Health § 41-41-11

Any person authorized and empowered to consent to surgical or medical treatment or procedures for himself or another may also waive the medical privilege for himself or the other person and consent to the disclosure of medical information and the making and delivery of copies of medical or hospital records. Any such waiver or consent shall survive the death of the person giving the same. No such waiver shall be needed for the cooperation with the furnishing of information to the State Department of Health, its representatives or employees in the discharge of their official duties. However, the State Department of Health shall not reveal the name of a patient with his case history without having first been authorized to do so by the patient, his personal representative, or legal heirs in case there be no personal representative.
