(a) Whenever a State or local law enforcement authority learns of a case of an illness, health condition, or unusual disease or symptom cluster, reportable pursuant to rules adopted by the Department or by a local board of health or local public health authority, or a suspicious event that may be the cause of or related to a public health emergency, as that term is defined in Section 4 of the Illinois Emergency Management Agency Act, it shall immediately notify the Illinois Emergency Management Agency and the Department or local board of health or local public health authority.

(b) Whenever the Department or a local board of health or local public health authority learns of a case of an illness, health condition, or unusual disease or symptom cluster, reportable pursuant to rules adopted by the Department or by a local board of health or a local public health authority, or a suspicious event that it reasonably believes has the potential to be the cause of or related to a public health emergency, as that term is defined in Section 4 of the Illinois Emergency Management Agency Act, it shall immediately notify the Illinois Emergency Management Agency, the appropriate State and local law enforcement authorities, other appropriate State agencies, and federal health and law enforcement authorities and, after that notification, it shall provide law enforcement authorities with such other information as law enforcement authorities may request for the purpose of conducting a criminal investigation or a criminal prosecution of or arising out of that matter. No information containing the identity or tending to reveal the identity of any person may be redisclosed by law enforcement, except in a prosecution of that person for the commission of a crime.

(c) Sharing of information on reportable illnesses, health conditions, unusual disease or symptom clusters, or suspicious events between and among public health and law enforcement authorities shall be restricted to the information necessary for the treatment in response to, control of, investigation of, and prevention of a public health emergency, as that term is defined in Section 4 of the Illinois Emergency Management Agency Act, or for criminal investigation or criminal prosecution of or arising out of that matter.

(d) The operation of the language of this Section is not dependent upon a declaration of disaster by the Governor pursuant to the Illinois Emergency Management Agency Act.
