Infectious Disease Reporting and Data

Infectious Disease Reporting and Data

Vermont’s list of reportable diseases and the time frames in which they are required to be reported to the Health Department are specified in Vermont law (Reportable and Communicable Disease Rule). 

The Vermont Department of Health depends on reports of diseases and conditions of public health concern to protect the health of Vermont residents. Timely reporting ensures that cases of communicable disease can be investigated quickly so steps can be taken to prevent the spread of the disease. Organizations and professionals who know or suspect that a person has (or has died of) a disease dangerous to the public’s health are required to report to the Health Department.

Health care providers and laboratories are required by law to notify the Health Department regarding patients with certain suspected or confirmed reportable diseases. Both laboratory confirmed and clinical diagnoses are reportable within 24 hours. Immediate reporting is essential for a limited number of conditions that require prompt public health follow-up (like measles and meningococcal disease), and for diseases that might indicate a bioterrorism incident.

Reportable and Communicable Disease Rule

  • School health officials
  • Administrators of long-term care and assisted living facilities
  • Any other health care provider, as defined by 18 V.S.A  9402
