Disease reporting
Health care providers and clinical laboratories are required by law to report cases and suspect cases of hepatitis A to local health departments within one working day of identification.
Cases are subject to restriction on school and day-care attendance, food handling, and patient care while in the communicable stage of the disease, or for the duration of any diarrhea and/or vomiting. If sufficient measures have been taken to prevent transmission, or the disease is no longer communicable, worksite, child-care and school restrictions can be removed by the local public health authority; school restrictions can be removed by a school nurse or health care provider; and health-care facility restrictions can be removed by the facility's infection control committee.
