Full Form of HDV
What is HDV?
Hepatitis Delta Virus (HDV) is a defective RNA virus that requires the presence of Hepatitis B Virus (HBV) for its replication and transmission. It causes the most severe form of viral hepatitis in humans, often leading to rapid progression to cirrhosis and hepatocellular carcinoma. In India, HDV infection is a significant public health concern, particularly among patients already infected with HBV. It is transmitted through contact with infected blood or bodily fluids, similar to HBV. Diagnosis is typically done through serological tests detecting anti-HDV antibodies or HDV RNA. The virus is most prevalent in the Amazon basin, parts of Africa, the Middle East, and Asia, including India. Treatment options are limited; pegylated interferon alpha is the only approved therapy, though newer antivirals are under development. Prevention primarily relies on HBV vaccination, as immunity against HBV prevents HDV infection. In Indian medical examinations such as NEET PG or AIIMS PG, HDV is a frequently tested topic in virology and hepatology, especially regarding its unique defective nature and clinical outcomes. Awareness and early detection are critical to managing the burden of this severe liver disease in India.

The patient with chronic HBV infection was also found to have HDV co-infection, which significantly increased his risk of liver failure.
HDV — frequently asked questions
What is the full form of HDV?
The full form of HDV is Hepatitis Delta Virus, a defective RNA virus that causes severe hepatitis in people already infected with Hepatitis B virus.
How is HDV transmitted in India?
HDV is transmitted through contact with infected blood or bodily fluids, similar to Hepatitis B, and is more common in people with chronic HBV infection or those who use injectable drugs.
Is there a vaccine for HDV in India?
There is no specific vaccine for HDV, but the Hepatitis B vaccine effectively prevents HDV infection as HDV requires HBV to replicate.
