Tuberculosis & Communicable Disease Control

PLEASE NOTE: As part of our response to COVID-19, the Health Department has announced changes to its schedule and services that impact this service area.

On-site scheduled PPD screening is on hold until further notice. Please call 203-854-7776 for more information. 

The Tuberculosis (TB) and Communicable Disease Control Program staff work with medical providers, educate the public, and perform disease surveillance, investigations, and contact tracing to prevent the occurrence and spread of infectious disease and epidemics.


The TB Control Program evaluates, diagnoses, and treats latent (inactive) TB disease with free medication. The division also provides TB screening and educational programs, and monitors TB activity within the community. Skin testing is also available by appointment for a $30 charge. With the report of an active case of TB, program staff will conduct an investigation of the disease to locate the source.

Other Communicable Diseases

The Communicable Disease Program conducts surveillance of all reportable communicable diseases in the Norwalk area. The division offers investigation and outbreak control of diseases such as bacterial meningitis, hepatitis, foodborne illnesses, rubella (German measles), and whooping cough.

The Health Department staff also act as contacts between state and local health care agencies to prevent diseases. In addition, staff are available to speak and provide educational programs for schools and community groups.
