How We Do Notifiable Disease Surveillance

Text Equivalent


  1. Patient
    A person feels ill and goes to the doctor.
  2. Healthcare Team
    Doctor diagnoses or laboratory  tests confirm a disease that is reportable by state law to the local or state public health department. Doctor or lab sends information about this disease to the local or state public health department.
  3. Public Health Department
    The public health department receives disease data and uses them to:
  • identify  and control disease outbreaks
  • ensure that the patient is effectively treated  so disease is not spread
  • provide  testing and preventive  care to those exposed to the disease
  • control sources of exposure.
  • The state public health department sends information about national notifiable  diseases to CDC.
