Pen. Code, § 7521

(a) When a parole or probation officer learns from responsible medical authorities that a supervised person in his or her custody has any of the conditions listed in Section 7520, but that the supervised person has not properly informed his or her spouse, the officer may ensure that this information is relayed to the spouse only through either the chief medical officer of the institution from which the person was released or the physician and surgeon treating the spouse or the supervised person. The parole or probation officer shall seek to ensure that proper counseling accompanies release of this information to the spouse, through the person providing the information to the inmate’s spouse.

(b) If a parole or probation officer has received information from appropriate medical authorities that one of his or her supervised persons is HIV infected or has AIDS or hepatitis B or C, and the supervised person has a record of assault on a peace officer, and the officer seeks the aid of local law enforcement officers to apprehend or take into custody the supervised person, he or she shall inform the officers assisting him or her in apprehending or taking into custody the supervised person, of the person’s condition, to aid them in protecting themselves from contracting AIDS or hepatitis B or C.

(c) Local law enforcement officers receiving information pursuant to this subdivision shall maintain confidentiality of information received pursuant to subdivision (b). Willful use or disclosure of this information is a misdemeanor. Parole or probation officers who willfully or negligently disclose information about AIDS or hepatitis B or C infection, other than as prescribed under this title or any other provision of law, shall also be guilty of a misdemeanor.

(d) For purposes of this section, “supervised person” means a person on parole, probation, mandatory supervision pursuant to paragraph (5) of subdivision (h) of Section 1170, or postrelease community supervision.
