Summary

Hepatitis C is a blood-borne viral infection. While rare in the UK, high-risk groups need protection through strict cross-infection control measures, as no vaccine is available.

Area of Science:

  • Hepatology
  • Virology
  • Infectious Diseases

Background:

  • Non-A, non-B hepatitis, now known as hepatitis C, is a significant viral infection transmitted via blood and blood products.
  • Infection often leads to chronic liver disease, despite being frequently asymptomatic initially.

Purpose of the Study:

  • To inform healthcare professionals, particularly in dentistry, about the risks and management of hepatitis C.
  • To emphasize the importance of cross-infection control in preventing transmission within healthcare settings.

Main Methods:

  • Review of transmission routes and risk factors for non-A, non-B hepatitis.
  • Assessment of current UK prevalence and at-risk populations.
  • Evaluation of existing preventative measures, including vaccination limitations.

Main Results:

  • Hepatitis C is primarily transmitted through blood and blood products.
  • Prevalence in the general UK population is low (<1%), but higher in specific risk groups.
  • Hepatitis B vaccination does not confer protection against hepatitis C.

Conclusions:

  • Standard cross-infection control procedures are essential for preventing hepatitis C transmission in healthcare.
  • Dental professionals and staff must adhere to rigorous protocols to protect both patients and themselves.
  • Ongoing vigilance is required due to the potential for chronic liver disease following infection.
