Nonetheless, the lack of an effective vaccine, the high rates of chronic infection and the limited effectiveness of treatment may cause concern for dental workers who come into contact with blood in : their daily practices. Description of the Disorder. The authors discuss the natural history, diagn osis and treatment, and patterns of transmission of HCV infection, includin g the Centers for Disease Control and Prevention's recommendations for mana gement and follow-up of health care workers after occupational exposure to HCV. Clinical Implications, In the absence of an effective vaccine or postexposu re prophylaxis, prevention of occupational transmission of HCV in dental se ttings continues to rely on the use of universal precautions, including bar rier precautions and the safe handling of sharp instruments.
