Disease Surveillance
Communicable diseases must be reported to the ACHD as specified in Pennsylvania’s Disease Control and Prevention Act of 1955. Public health officials use reports to identify disease clusters, determine at-risk populations, assess burden of disease, monitor trends, and recommend measures to stop disease transmission.
