There are a set of diseases that the Health Department is required to monitor. When a patient from Langlade County has a positive test result for one of these specific diseases, no matter where the testing occurred, the lab directly sends us the information. We are then required by the State of Wisconsin to follow up with the patient and conduct an interview to collect information relevant to the disease. This allows us to track any commonalities if an outbreak were to occur, and helps us to control the source of the illness.
