Hepatitis D or delta virus (HDV) is a defective single-stranded RNA virus requiring the presence of hepatitis B virus (HBV) for its expression and replication. HDV is a 35- to 37-nm spherical particle enveloped by a lipoprotein coat derived from HBsAg. HDV-RNA consists of 1680 nucleotides, and replication is limited to hepatocytes.

In most cases, HDV is the dominant virus in the infection. As it suppresses HBV to low levels, it utilizes HBV's surface proteins to as...
Arguably the biggest challenge in diagnosing hepatitis D is recognizing the signs of infection. Because hepatitis D is uncommon in the United States, it can sometimes be overlooked in a patient—particularly in cases of HBV/HDV coinfection. By contrast, HDV superinfection is often recognized by the sudden worsening of symptoms in people previously d...

Treatment guidelines for sexually transmitted infections (STIs), updated by the Centers for Disease Control and Prevention (CDC) in 2021, note that there is no specific treatment available for people experiencing acute hepatitis B. People with chronic hepatitis B sh...
The best way to prevent hepatitis D is to prevent hepatitis B. By getting vaccinated with one of three approved hepatitis B vaccines—Engerix-B, Recombivax HB, or Heplisav B—you can prevent HDV from causing harm if you do get infected. Although HDV can enter cells on its own, it cannot replicate without HBV. Without the means to rapidly grow, HDV ca...
Hepatitis D cannot be cured, so a person will need to take care of their liver by making changes to their diet and lifestyle, such as: 1. Avoiding alcohol: Alcohol not only damages liver cells but also causes fat to build up in the liver, leading to hepatic steatosis(fatty liver disease). 2. Stopping cigarettes:Cigarette smoke can aggravate already...
