Hepatitis D is a liver disease caused by the hepatitis D virus (HDV) and is considered uncommon in the United States. It is a satellite virus, which means it can only infect people who are also infected with the hepatitis B virus (HBV). There is currently no vaccine for hepatitis D, but vaccination against hepatitis B can prevent HDV infection. This is because hepatitis D requires hepatitis B virus for its replication and cannot occur in the absence of HBV.

What You'll Learn
- Hepatitis D is a liver disease caused by the hepatitis D virus (HDV)
- HDV requires hepatitis B virus (HBV) for its replication
- There is no hepatitis D vaccine, but the hepatitis B vaccine protects you from hepatitis D
- HDV spreads through contact with an infected person's blood or other body fluids
- Symptoms of hepatitis D include severe liver damage and can lead to death
Hepatitis D is a liver disease caused by the hepatitis D virus (HDV)
The hepatitis D virus spreads through contact with an infected person's blood or other body fluids. This can occur through sharing needles, having sex with an infected person, or coming into contact with their open sores. It can also spread from mother to child during birth, although this is rare. People who are at an increased risk of hepatitis D include those who are already infected with HBV, people who inject drugs, men who have sex with men, and those with hepatitis C or HIV infections.
There is currently no vaccine specifically for hepatitis D. However, vaccination against hepatitis B can prevent HDV infection. This is because the hepatitis B vaccine prevents HBV, which is necessary for the replication of HDV. Therefore, the best way to prevent hepatitis D is to take steps to prevent hepatitis B infection, such as getting vaccinated. Other preventative measures include not sharing needles or personal items that may have come into contact with an infected person's blood, such as razors or toothbrushes.
If a person contracts hepatitis D, they may experience severe symptoms and serious illness. Doctors diagnose hepatitis D through a person's medical history, a physical exam, and blood tests. Treatment options include a prescription medication called interferon, which can help treat some people with hepatitis D. It is also recommended that those with hepatitis D choose healthy foods and drinks and avoid alcohol to prevent further liver damage.

HDV requires hepatitis B virus (HBV) for its replication
Hepatitis D virus (HDV) is a communicable and serious liver disease that requires the hepatitis B virus (HBV) for its replication. HDV affects an estimated 5% of people globally who have a chronic infection with HBV. This amounts to approximately 12 million people.
HDV is considered a hybrid virus as it uses the HBV surface antigen (HBsAg) as its envelope protein, rendering it able to infect only patients that concomitantly harbour HBV. In other words, HDV is dependent on HBV for its transmission and spread. HDV infection can only occur in the presence of HBV, and people who are not immune to HBV are at risk of HDV infection. Those who are more likely to have HBV and HDV co-infection include indigenous people, people who inject drugs, and people with hepatitis C virus or HIV infection.
The risk of HDV infection also appears to be potentially higher in recipients of haemodialysis, men who have sex with men, and commercial sex workers. HDV superinfection markedly accelerates progression to cirrhosis when compared with HBV mono-infected persons. Patients with HDV-induced cirrhosis are at an increased risk of hepatocellular carcinoma (HCC). However, the mechanism by which HDV causes more severe hepatitis and a faster progression of fibrosis than HBV alone remains unclear.
Vaccination against hepatitis B can prevent HDV infection. Therefore, hepatitis D prevention services should focus on reducing HBV transmission through hepatitis B immunization, including timely birth doses, additional antiviral prophylaxis for eligible pregnant women, blood safety, safe injection practices in healthcare settings, and harm reduction services with clean needles and syringes.

There is no hepatitis D vaccine, but the hepatitis B vaccine protects you from hepatitis D
Hepatitis D is a serious liver disease that causes inflammation of the liver. It is considered uncommon in the United States, but it is most common in Eastern Europe, Southern Europe, the Mediterranean region, the Middle East, West and Central Africa, East Asia, and the Amazon Basin in South America. This disease is caused by the hepatitis D virus (HDV), which requires the hepatitis B virus (HBV) for its replication. Therefore, only people with hepatitis B can contract hepatitis D.
The hepatitis D virus spreads through contact with an infected person's blood or other body fluids, such as through sharing needles or other materials used to inject drugs, having sex with an infected person, or coming into contact with blood from open sores. It rarely spreads from mother to child during birth. However, it is important to note that hepatitis D is not spread through food or water, sharing eating utensils, breastfeeding, hugging, kissing, hand-holding, coughing, or sneezing.
Currently, there is no vaccine specifically for hepatitis D. However, because hepatitis D requires the presence of hepatitis B to replicate, getting vaccinated against hepatitis B also protects you from hepatitis D. This is because the hepatitis B vaccine prevents hepatitis B infection, which is necessary for an individual to contract hepatitis D. Therefore, the expansion of childhood hepatitis B immunization programs has resulted in a decline in hepatitis D incidence worldwide.
If you already have hepatitis B, you can take steps to prevent hepatitis D infection by not sharing needles or other materials used to inject drugs, wearing gloves if you must touch another person's blood or open sores, and not sharing personal items such as toothbrushes, razors, or nail clippers. It is also important to get tested for hepatitis B and D if you think you may have been exposed, as this can help prevent the spread of the infection to others.

HDV spreads through contact with an infected person's blood or other body fluids
Hepatitis D is a liver disease caused by the hepatitis D virus (HDV). It is not a stand-alone virus and requires the hepatitis B virus (HBV) for its replication. In other words, only people with hepatitis B can contract HDV. Therefore, the hepatitis B vaccine, which prevents hepatitis B, also prevents hepatitis D.
- Sharing needles or other materials used to inject drugs with an infected person.
- Exposure to blood from open sores of an infected person.
- Needle sticks or exposure to sharp instruments that may have come into contact with the blood of an infected person.
- Sharing personal items such as razors, toothbrushes, or nail clippers that may have been contaminated with the blood of an infected person.
- Having sex with an infected person.
It is important to note that hepatitis D cannot be spread through food or water, sharing eating utensils, breastfeeding, hugging, kissing, hand-holding, coughing, or sneezing.

Symptoms of hepatitis D include severe liver damage and can lead to death
Hepatitis D is a serious liver disease caused by the hepatitis D virus (HDV). It is an inflammation of the liver that can lead to severe liver damage and even death. HDV is known as a "satellite virus" as it can only infect people who are also infected with the hepatitis B virus (HBV)—it requires HBV for its replication and cannot exist without it.
The symptoms of hepatitis D are often more severe than those of other types of acute viral hepatitis infections, and it can progress rapidly towards hepatocellular carcinoma and liver-related death. Patients with HDV-induced cirrhosis are at a heightened risk of hepatocellular carcinoma. However, the mechanism by which HDV causes more severe hepatitis and a faster progression of fibrosis than HBV alone is not yet fully understood.
The hepatitis D virus spreads through contact with an infected person's blood or other body fluids, such as through sharing needles, having sex with an infected person, or coming into contact with their open sores. It rarely spreads from mother to child during birth. Those at an increased risk of contracting hepatitis D include people who inject drugs, sex partners of those infected with HBV and HDV, people coinfected with HIV and HBV, men who have sex with men, and indigenous people.
While there is currently no vaccine specifically for hepatitis D, getting vaccinated against hepatitis B can prevent HDV infection. This is because hepatitis D cannot occur in the absence of HBV. Therefore, preventing hepatitis B will also prevent hepatitis D. Antiviral medication, such as interferon, can be used to treat hepatitis D.
