WHO Calls for Urgent action against Hepatitis D,Now classified as Carcinogenic
Table of Contents
The World Health Institution (WHO) is urging global action to control Hepatitis D,recently classified as “carcinogenic to humans” by the International Agency for Research on Cancer (IARC). This classification places Hepatitis D alongside Hepatitis B and C as a known cause of cancer. WHO News Release
Understanding Hepatitis D
Hepatitis D is a liver infection caused by the Hepatitis D virus (HDV). it’s unique because it can onyl infect people who are already infected with Hepatitis B. HDV relies on Hepatitis B virus (HBV) for its replication and spread. Therefore, preventing Hepatitis B through vaccination also prevents Hepatitis D. CDC – Hepatitis D
How Hepatitis D Leads to Cancer
Chronic Hepatitis D infection can lead to cirrhosis (scarring of the liver) and liver failure. Cirrhosis, irrespective of the cause, significantly increases the risk of developing hepatocellular carcinoma (HCC), the most common type of liver cancer. The IARC classification confirms the direct link between chronic HDV infection and HCC development. National Cancer Institute – Liver Cancer Prevention
WHO’s Call to Action
The WHO has issued a strong call to governments and partners to accelerate efforts to eliminate viral hepatitis as a public health threat. This includes:
- Increased Vaccination Coverage: Expanding access to Hepatitis B vaccination, which also protects against Hepatitis D.
- Improved Testing and Diagnosis: Scaling up testing for Hepatitis B and D, particularly among high-risk populations.
- Access to Treatment: Ensuring access to affordable and effective treatments for both Hepatitis B and D. Currently, treatment for Hepatitis D is limited, but research is ongoing. WHO – Viral hepatitis Fact Sheet
- Public Awareness Campaigns: Raising awareness about viral hepatitis, its prevention, and treatment options.
The Global Burden of Hepatitis D
An estimated 5% of people with chronic Hepatitis B are also infected with Hepatitis D, representing around 15-20 million people globally. Hepatitis D is particularly prevalent in certain regions, including parts of Asia, Africa, and the Amazon basin.The infection can be more severe than Hepatitis B alone,leading to a faster progression to cirrhosis and liver failure.

Key takeaways
- Hepatitis D has been classified as carcinogenic to humans by the IARC.
- Hepatitis D requires Hepatitis B to exist and spread.
- Vaccination against Hepatitis B provides protection against Hepatitis D.
- The WHO is urging increased global efforts to eliminate viral hepatitis.
- Early diagnosis and treatment are crucial for preventing severe liver disease and cancer.
The WHO’s renewed focus on Hepatitis D underscores the urgent need for a complete global strategy to combat viral hepatitis and reduce its devastating impact on public health.Continued research, increased funding, and collaborative efforts are essential to achieve the goal of eliminating viral hepatitis as a public health threat by 2030.
