2. Hepatitis D is a defective form of the virus that needs Hepatitis B to exist.

A) True

B) False

The given statement is true.

Explanation:

HDV or hepatitis D virus refers to a virus, which needs hepatitis B virus for its replication. The HDV infection takes place concurrently or as super-infection with hepatitis B virus. About five percent of individuals with chronic HBV infection are co-infected with HDV, causing a sum of 15 to 20 million individuals infected with HDV globally.

The co-infection of HDV-HBV is regarded to be the most extreme kind of chronic viral hepatitis because of the rapid cases of liver-associated death and hepatocellular carcinoma. The infection of hepatitis D can be prevented with the application of hepatitis B vaccines.
