Hepatitis: protecting BMETs & CEs.
Hepatitis is the primary occupational hazard for healthcare workers. Not until the 1970s were hepatitis viruses isolated and identified as types A and B. In the late 1970s, hepatitis D was discovered as a major cause of fulminant hepatitis. Soon, it was evident that another type was also at work. Because testing was only available for types A and B, the new category was referred to as non-A, non-B. In the 1980s, scientists identified two more viruses from this non-A, non-B group, namely hepatitis E and hepatitis C. These five types of hepatitis have different modes of transmission. The fecal-to-oral route is the mode of transmission for hepatitis types A and E. But, types B and D are bloodborne pathogens. With the advent of a safe vaccine for hepatitis B, this category is declining. To date, hepatitis C appears to have multiple routes of transmission, with half the cases being posttransfusion. In the United States, 85,000 people per year develop chronic hepatitis C, which ultimately leads to severe liver damage. This paper addresses each of the five viruses that have been grouped by routes of transmission, prevention techniques for BMETs and CEs, and statistics of reported cases to the Centers for Disease Control and Prevention (CDCP) over the last 20 years.
