Current through Register Vol. 48, No. 28, July 12, 2024
a)
				Investigation of Outbreaks
1) Any pattern of
				cases, or increased incidence of any illness beyond the expected number of
				cases in a given period, that may indicate an outbreak, including but not
				limited to suspected or confirmed outbreaks of foodborne or waterborne disease,
				or outbreaks transmitted by laboratory acquisition, animal contact,
				person-to-person contact, inhalation or other transmission method, or in
				healthcare settings due to breaches in infection control practices shall be
				reported to the local health authority within 24 hours. Outbreaks shall be
				reported if there is a public health significance to the event, including, but
				not limited to, evidence of severe illness (deaths or hospitalizations),
				institutional outbreaks, outbreaks involving a population at increased risk for
				severe complications, outbreaks of reportable diseases or conditions, outbreaks
				of unknown etiology, outbreaks with a controllable source, or outbreaks which
				are very large or rapidly progressing or if there is the possibility of
				transmission to humans from animals.
2) All suspected or confirmed foodborne
				outbreaks shall be investigated by the local health authority where the food
				was prepared, or by the Department or another relevant agency (e.g., Illinois
				Department of Agriculture, federal Food and Drug Administration) if the local
				authority does not have regulatory authority or is unable to perform the
				investigation. If multiple jurisdictions are involved, the jurisdiction where
				the food was prepared shall be in charge of the investigation unless determined
				otherwise. All suspected or confirmed outbreaks not caused by foodborne
				transmission shall be investigated by the local health authority where the
				exposure occurred.
3) If the
				investigation determines that an outbreak has occurred, the jurisdiction in
				charge of the investigation shall enter the outbreak within 24 hours from
				notification from outbreak facility or cluster detection by local health
				authority into the Department's ORS. Within 30 days of the end of the outbreak
				investigation, the final information shall be entered into ORS.
4) When outbreaks occur in any business,
				organization, institution, private home or health care facility, staff in the
				establishment where the outbreak occurred may be considered to be contacts to
				cases and may be required by the local health authority to submit specimens for
				testing.
5) Reporting entities, as
				defined in Section 690.200(a)(1),
				are required to report any known or suspected common-source outbreaks and any
				intoxication caused by marine organisms, including paralytic shellfish
				poisoning, ciguatera and scombroid.
6) See Section
				690.20(a)(9) and
				(a)(10) for guidance on the control of viral
				gastroenteritis outbreaks.
