Surveillance

HCV Surveillance - Couple outdoors

Since hepatitis C (HCV) first began to be tracked by the Vermont Department of Health, over 7,000 people in Vermont have been reported as having acute or chronic HCV All health care providers and laboratories serving Vermont are required by the state to report all positive HCV tests. HCV test results that are reported to the Health Department are kept confidential and are assessed for follow up by surveillance staff. Confirmed cases are then reported to the Centers for Disease Control and Prevention (CDC) through the National Electronic Disease Surveillance System (NEDSS). On this page you will find selected Vermont HCV surveillance information. HCV surveillance is particularly challenging in light of CDC’s estimate that up to 50% of people living with the infection in the U.S. do not know they have it. As a result, the information presented below may not reflect the many Vermonters who are likely infected with HCV but unaware of their status. It may also include HCV cases among people who are no longer living in Vermont (people who moved away or passed away).
