Hepatitis Viruses

Key Points

  • Hepatitis A (HAV), hepatitis B virus (HBV), and hepatitis C virus (HCV) are prevalent and infectious causes of liver disease.
  • HBV infection is preventable through vaccination, most commonly administered in 2 or 3 injections over the course of 6 months.
  • Although there is no vaccine for HCV, current treatment regimens can cure more than 90% of cases.
  • Careful medical histories can capture insight about patients to help identify those potentially posing infection risk.
  • Treatment plans need to be adapted to optimize patient management according to their unique medical condition(s).
  • Dentists and all staff with direct patient contact should comply with all standard precautions (e.g., wearing appropriate personal protective equipment and disinfecting all equipment and surfaces after each patient) for all patients.
