Notwithstanding any other provision of law, a minor 12 years of age or older who may have come into contact with any sexually transmitted disease as designated by the State Board of Health may give consent to the furnishing of medical care related to the diagnosis or treatment of such disease, provided a duly licensed practitioner of medicine in Alabama authorizes such diagnosis and treatment. The consent of the minor shall be as valid and binding as if the minor had achieved his or her majority, as the case may be. Such consent shall not be voidable nor subject to later disaffirmance because of minority. The medical provider or facility of whatever description providing diagnostic procedures or treatment to a minor patient who has come into contact with any designated sexually transmitted disease, may, but shall not be obligated to, inform the parent, parents or guardian of any such minor as to the treatment given or needed.
