Working with health care providers, schools, and childcare staff, the program investigates confirmed and suspected cases of reportable diseases. 

Surveillance, or the collection and analysis of data from infected and exposed individuals, helps to identify the cause of diseases to prevent and control their spread. Communicable diseases can be passed from person to person. Some examples are pertussis or whooping cough, measles, tuberculosis and hepatitis.
