Hepatitis C virus (HCV) has recently been recognized as an emerging pathogen of surprising proportions.
The clinical liver illness associated with HCV infection can be minimal or none, but in a notable number of persons it can ultimately cause debilitating chronic liver disease, fibrosis, cirrhosis, and hepatic failure, and it is likely related to an increased incidence of hepatocellular carcinoma.
From 1991 to 1994, an annual electronic census was sent to 168 Veterans Health Administration facilities requesting serologic data on HCV in patients seen in Department of Veterans Affairs facilities.
Response rate to the mandatory survey was 100%. In 1991,6,612 individual patients were reported as positive for HCV antibody in the Department of Veterans Affairs system.
This increased yearly from 1992 to 1994 with 8,365,14,097, and finally 18,854 persons, respectively.
This represents an increase of more than 285% during the 4-year period.
Increases in HCV antibody for the same period were seen in all major regions of the United States and in the specified large metropolitan areas.
In the New York area and in coastal California, this trend of new case identification may have plateaued during 1993 and 1994.
Overall, total patients seen nationally in the Veterans Health Administration increased by only 4.87% during the same period, 1991 to 1994.
Thus, the increase in persons positive for HCV antibody is not based on work load alone. (...)
