The World Health Organization (WHO) has officially classified Hepatitis D as a carcinogen. This decision emphasizes the critical role of the Hepatitis B vaccine in providing protection and preventing co-infection. Learn more about the significance of this classification and the importance of vaccination in safeguarding against these viruses.
What Makes Hepatitis D Dangerous?
- Hepatitis D (HDV) relies on the presence of the Hepatitis B virus (HBV) to cause infection.
- Co-infection or superinfection with Hepatitis B is necessary for Hepatitis D to affect individuals.
- HDV enhances the risk of liver cancer significantly when combined with HBV.
How Does Hepatitis D Spread?
- Transmission of HDV occurs through blood transfusions, sharing needles, and sexual contact.
- In India, certain high-risk groups may have a higher prevalence of HDV infection.
Diagnosis and Prevention
- Diagnosing Hepatitis D involves a blood test for HDV-RNA.
- Vaccination against Hepatitis B is crucial for preventing Hepatitis D.
- Additional preventive measures include safe blood transfusion practices and safe sex practices.
Long-Term Risks and Treatment Challenges
- Co-infection with HBV and HDV poses a higher risk of liver cirrhosis and cancer.
- Treatment of Hepatitis D remains challenging, with limited access to newer antiviral therapies.
Why the WHO Classification Matters
- WHO’s classification of Hepatitis D as carcinogenic will lead to increased research funding and public health awareness.
- Stronger screening and vaccination campaigns are expected following this classification.
Key Takeaways for Competitive Exams:
- Hepatitis D is now classified as a cancer-causing virus by the WHO.
- Vaccination against Hepatitis B is essential for protection against Hepatitis D.
- Preventive measures and early diagnosis play a crucial role in managing these viruses.
- Increased global efforts are needed to address the risks associated with Hepatitis D.
