Reporting of Diseases, Emergency Illnesses, Health Conditions, and Laboratory Findings


Disease reporting and surveillance are important functions to monitor the status of the public's health. It allows the Connecticut Department of Public Health (DPH) to determine the epidemiology of diseases, see trends and establish preventive measures. The DPH and an advisory committee consisting of public health officials, clinicians and laboratorians, contribute to the process of updating the list of diseases for surveillance.

In accordance with Sections 19a-36-A3 and 19a-36-A4 of the Public Health Code and Sections 19a-2a and 19a-215 of the Connecticut General Statutes, diseases on the lists of reportable diseases, emergency illnesses and health conditions, and laboratory reportable significant findings are required to be reported to the DPH and the Local Health Director of the town in which the patient resides. These lists are reviewed annually and revised when necessary. The list of reportable diseases and laboratory findings are outlined annually in the  Connecticut Epidemiologist newsletter.



Disease Specific Reporting Forms

All forms are found on the DPH Forms page and most of them are fillable PDF forms. The primary disease reporting form for providers is the Reportable Disease Confidential Case Report Form PD-23. Laboratories use electronic laboratory reporting or the Reportable Laboratory Findings Form OL-15C to report diseases related to public health. Disease specific forms are available for the diseases listed below. 

Please use the on-line forms as much as possible. Copies of the 3-ply PD-23 and OL-15C can be ordered by calling the Epidemiology and Emerging Infections Program at 860-509-7994.
