Hepatitis D, also known as “delta hepatitis,” is a liver infection caused by the hepatitis D virus (HDV). Hepatitis D only occurs in people who are also infected with the hepatitis B virus.

In combination with hepatitis B virus, hepatitis D has the highest fatality rate of all the hepatitis infections, at 20%. A recent estimate from 2020 suggests that currently 48 million persons are infected with this virus.

In cases where a liver transplant is needed, approximately 70 percent of people live 5 years or longer after the operation.

Sources: Humans are the reservoir for hepatitis D, which is usually transmitted by contact with blood or body fluids, particularly sharing drug paraphernalia. Humans and animals (swine) are the reservoir for hepatitis E which is transmitted most commonly through fecally contaminated food, water, and environment.

Who is at risk? Chronic HBV carriers are at risk for infection with HDV. People who are not immune to HBV (either by natural disease or immunization with the hepatitis B vaccine) are at risk of infection with HBV which puts them at risk of HDV infection.

Hepatitis B is a life-threatening liver infection that is caused by the hepatitis B virus, whereas, hepatitis D infection only occurs in people who are infected with the hepatitis B virus. It replicates autonomously within hepatocytes, but requires hepatitis B surface antigen for proliferation.

Hepatitis D virus is transmitted in several ways. It can pass via blood, or contact with other body fluids such as semen, vaginal fluid, or saliva of an infected person.

Most adults with hepatitis B recover fully, even if their signs and symptoms are severe. Infants and children are more likely to develop a chronic (long-lasting) hepatitis B infection. A vaccine can prevent hepatitis B, but there’s no cure if you have the condition.

Diagnosis of hepatitis B infection Acute hepatitis B is a clinical diagnosis identified by the detection of HBsAg, symptoms, high serum aminotransferases. Usually anti-HBc IgM can be detected and HBV DNA is present. HBeAg can also be identified in most acute phase of infections, but has little clinical importance.

Most adults who acquire HBV clear the virus within a few months, and their hepatitis B surface antigen test result will be negative after that time. Some people remain infected and continue to test positive for hepatitis B surface antigen.

Persons who do not respond to the primary hepatitis B vaccine series (i.e., anti-HBs <10 mIU/mL) should complete a second vaccine series or be evaluated to determine if they are HBsAg-positive. For the second series, a different brand of vaccine should be administered.

Those who no longer have protective levels of antibody against the hepatitis B virus will be offered a booster dose of the hepatitis B vaccine….Duration of Long-term Immunity After Hepatitis B Virus Immunization.

To put it simply, yes, a person living with hepatitis B can get married. In fact, a healthy relationship can be a source of love and support for those who may feel alone in their diagnosis. Transmission of hepatitis B can be prevented in your partner; it’s a vaccine preventable disease!

A positive anti-HBs (or HBsAb) test result means you are “immune” and protected against the hepatitis B virus and cannot be infected. You are not infected and cannot spread hepatitis B to others.

Anyone who lives with or is close to someone who has been diagnosed with chronic Hepatitis B should get tested. Hepatitis B can be a serious illness, and the virus can be spread from an infected person to other family and household members, caregivers, and sexual partners.

The estimated carrier life expectancy is 71.8 years, as compared to 76.2 years among noncarriers (Figure ​ 5). These results are consistent with other estimates, which indicate that 15% to 40% of HBV carriers die of liver complications.

No. Hepatitis B is a sexually transmitted disease, but it is spread in other ways, too. This is a hardy virus that can exist on almost any surface for up to one month. You can get infected through contact with an infected person’s blood or body fluids.

Hepatitis B (HBV) is 50 to 100 times easier to transmit sexually than HIV ( the virus that causes AIDS). HBV has been found in vaginal secretions, saliva, and semen. Oral sex and especially anal sex, whether it occurs in a heterosexual or homosexual context, are possible ways of transmitting the virus.

Hepatitis B is spread when blood, semen, or other body fluid infected with the hepatitis B virus enters the body of someone who is not infected. People can become infected with the virus from: Birth (spread from an infected mother to her baby during birth)

Hepatitis A is caused by the hepatitis A virus (HAV). The virus is found in the stool (feces) of HAV-infected people.

Several antiviral medications — including entecavir (Baraclude), tenofovir (Viread), lamivudine (Epivir), adefovir (Hepsera) and telbivudine (Tyzeka) — can help fight the virus and slow its ability to damage your liver. These drugs are taken by mouth. Talk to your doctor about which medication might be right for you.

Hepatitis B can’t be cured, but it almost always goes away on its own. There are medications that can help treat long-lasting hepatitis B infections.

If the virus has been in the blood for more than 6 months, it is considered a permanent (or chronic) hepatitis B infection. About 15 to 40% of individuals develop chronic hepatitis B. Chronic hepatitis B, if left untreated, can cause serious liver injury and increase the chance of liver cancer.

That diet should include:

• Plenty of fruits and vegetables.
• Whole grains such as oats, brown rice, barley, and quinoa.
• Lean protein such as fish, skinless chicken, egg whites, and beans.
• Low-fat or non-fat dairy products.
• Healthy fats like those in nuts, avocados, and olive oil.

Those who are more likely to have HBV and HDV co-infection include people who inject drugs, indigenous people and people with hepatitis C virus or HIV infection. The risk of co-infection also appears to be potentially higher in recipients of hemodialysis, men who have sex with men and commercial sex workers.

While hepatitis C tends to get more attention and research funding, hepatitis B is considerably more common and causes more liver-related cancer and death worldwide than hepatitis C. Combined, chronic hepatitis B and C account for approximately 80% of the world’s liver cancer cases.

Key points about alcoholic hepatitis Hepatitis is inflammation of the liver that leads to liver cell damage and cell death. Alcoholic hepatitis is caused by drinking too much alcohol. The liver breaks down alcohol and if, over time, you drink more alcohol than the liver can process, it can become seriously damaged.

There are 3 main types of hepatitis: hepatitis A, B, and C. Hepatitis C can be more severe and is the most deadly, but even those with acute illness can recover without lasting liver damage. Up to 70% of those chronically infected with hepatitis C develop chronic liver disease, and up to 20% develop cirrhosis.

A person can have and spread hepatitis A, even if that person does not have any symptoms. In fact, hepatitis A is most contagious before symptoms appear.
