Hepatitis B is a serious liver disease caused by the hepatitis B virus (HBV). It is characterized by inflammation of the liver that may lead to cirrhosis (scarring and hardening of the liver tissues), liver damage, liver cancer, and, sometimes, even death.
Babies who get hepatitis B at birth are more likely to get a chronic infection. However, in adults, it may not last long because the body fights off the infection within a few months, making them immune for the rest of their life.
There is no permanent cure available yet. However, for chronic hepatitis B, maintaining a healthy diet and lifestyle, avoiding alcohol, and proper treatment can slow down the disease progression, reduce the chances of liver cancer, and increase the chances of surviving.
An annual visit to the doctor is highly recommended to determine liver health using blood and imaging tests. Early detection leads to a better treatment outcome.
What is hepatitis B?
Hepatitis B is a liver infection caused by the hepatitis B virus (HBV) that can affect people of all ages and is commonly found throughout the world.
Around the world, there are about 292 million infected people. The United States alone exceeds 2 million infections.
2 types of hepatitis B
- Acute: An initial infection caused by the hepatitis B virus. Most people (approximately four out of every five infected adults) can recover from this acute infection.
- Chronic: If the infection lasts for more than six months, it is termed chronic hepatitis B, which is the type that leads to severe liver inflammation, scarring, and liver cancer.
What are the symptoms of hepatitis B?
Some may not show any signs and symptoms, whereas some recently infected people may present with mild to intense symptoms that last for weeks, which may include:
- Muscle or joint pain
- Abdominal pain
- Decreased appetite
- Weakness or lack of energy
- Jaundice (yellowing of the skin or eyes)
- Passing light-colored urine
How does hepatitis B spread?
A person may get infected with the hepatitis B virus through exposure to body fluids of an infected person, such as blood and semen.
People can get the infection by:
- Unprotected sex with the infected person
- Sharing or using infected needles for medications, drugs, piercings, and tattoos
- Sharing daily routine items (containing body fluids), such as toothbrushes, nail cutters, razors, or piercing jewelry
- Getting treated with unsterile or infected surgical instruments
- Getting bitten by the infected person
- Being born to an infected pregnant female
- Blood transfusions and organ transplants
Be aware that hepatitis B does not spread by:
- Hugging, shaking hands, or touching
- Cheek or lip kissing
- Sneezing or coughing
- Consuming food prepared or touched by an infected person
- Breastfeeding (mother to child transmission is negligible through breastfeeding if the baby receives timely hepatitis B immunoglobulin and vaccine)
- Sharing utensils, such as spoons or forks
Risk factors of hepatitis B virus
People who unknowingly carry the virus in their blood without any signs and symptoms and can infect others are called “hepatitis B carriers.” (Children born to infected mothers are at a higher risk of being carriers.)
People at risk for getting hepatitis B infection include:
- People having unprotected sex or are diagnosed with other sexually transmitted diseases
- Children born to infected women
- Health-care providers
- People who tend to share needles
- People living in high-risk countries
- Vulnerable people living in prisons and old age homes
- People on dialysis
- Men who have sex with men
- Human immunodeficiency virus-positive people
3 ways to diagnose hepatitis B
The virus can get easily detected within 30 to 60 days of infection or almost after 90 days of initial exposure to the virus. Most people often get to know they are infected when they opt for blood donations.
The three primary ways to diagnose hepatitis B virus (HBV) include:
- Blood examination: A blood serum or plasma test enables one to know the presence of the virus.
- Hepatitis B surface antigen and antibody (HBsAg): Antigens are proteins present on the HBV, and antibodies are proteins made by the immune cells of the body. These may be seen in the blood between 1 and 10 weeks after exposure and may vanish once you recover after four to six months.
- Hepatitis B surface antibody (anti-HBs): These antibodies are responsible for lifelong immunity and are seen in the blood once the hepatitis antigen disappears.
- Abdominal ultrasonography: An ultrasound shows the size, shape, and blood flow to the liver.
- Liver biopsy: Liver tissue sample is removed through a small incision and analyzed under the microscope.

How is hepatitis B treated?
More than 90 percent of adults infected with hepatitis B ultimately recover from their symptoms.
Acute hepatitis B
Medical treatment is not required. The healthcare provider may recommend:
- Plenty of fluids
- Adequate rest
- Maintaining a healthy diet
- Avoiding alcohol consumption
Chronic hepatitis B
Drug therapy is recommended for active liver disease.
- Injectable interferons, such as interferon alfa and pegylated interferon.
- Antivirals, such as adefovir dipivoxil, entecavir, lamivudine, telbivudine, and tenofovir alafenamide
In rare cases of advanced hepatitis B, a liver transplant may be done.
Can hepatitis B be prevented?
Hepatitis B virus is contagious. The best way to prevent the infection is by getting vaccinated.
According to the World Health Organization (WHO), the vaccine is 98 to 100 percent effective in guarding against the virus, safe, and widely available.
Though not confirmed, some studies suggest vaccine effectiveness lasts for the entire life, and a few studies speculate it to be effective for 20 years. If a person is exposed to the hepatitis B virus (HBV) and is not vaccinated against HBV or they aren’t sure of their vaccination status, the doctor may administer hepatitis B immunoglobulin, preferably within 12 hours of the exposure to prevent the disease. This may be followed by vaccination against hepatitis B.

Hepatitis B (HBV, Hep B)The hepatitis B virus (HBV, hep B) is a unique, coated DNA virus belonging to the Hepadnaviridae family of viruses. The course of the virus is determined primarily by the age at which the infection is acquired and the interaction between the virus and the body's immune system. Successful treatment is associated with a reduction in liver injury and fibrosis (scarring), a decreased likelihood of developing cirrhosis and its complications, including liver cancer, and a prolonged survival.

How Does a Person Get Hepatitis?There are various types of hepatitis, which a person can get by food or water contaminated with the fecal matter of an infected person, sexual contact, blood transfusion, sharing needles, direct contact with an infected person’s blood or body fluid, transfer from mother to the fetus, tattoo needles, or needle prick.
Is Hepatitis B Contagious?
Hepatitis B is a type of liver infection. Hepatitis B is spread through person-to-person contact or through personal items like razors, toothbrushes, etc. Symptoms of hepatitis B include fever, yellowish skin (jaundice), dark urine, fatigue, nausea, and vomiting. There is no drug to cure hepatitis B; however, there is a hepatitis B vaccine available.
Is Hepatitis Contagious?Hepatitis means "inflammation of the liver," and there are several different types of such as A, B, C, D, and E. Some types of hepatitis are contagious and some types are not. Hepatitis symptoms vary upon the type of disease; however, the following symptoms may develop in someone with hepatitis: fatigue, nausea and vomiting, abdominal pain and discomfort, jaundice (yellowing of the skin and whites of the eyes), and loss of appetite. Treatment for hepatitis depends upon the cause. Some types of hepatitis have a vaccine to prevent spread of disease such as hepatitis A and B.

Hepatitis (Viral Hepatitis A, B, C, D, E, G)
Hepatitis is most often viral, due to infection with one of the hepatitis viruses (A, B, C, D, E, F (not confirmed), and G) or another virus (such as those that cause infectious mononucleosis, cytomegalovirus disease). The main nonviral causes of hepatitis are alcohol and drugs. Many patients infected with hepatitis A, B, and C have few or no symptoms of illness. For those who do develop symptoms of viral hepatitis, the most common are flu-like symptoms including: loss of appetite, nausea, vomiting, fever, weakness, tiredness, and aching in the abdomen. Treatment of viral hepatitis is dependent on the type of hepatitis.
What Does it Mean If You Have Urobilinogen in Your Urine?Urobilinogen is a substance that is produced when bilirubin, a waste product produced by the breakdown of red blood cells, is processed in the liver and released into the intestine. Excess urobilinogen in urine may indicate liver diseases, such as viral hepatitis, cirrhosis, or liver damage. It is caused by drugs, toxic substances, or conditions associated with increased red blood cell destruction (hemolytic anemia). In a person with low urine urobilinogen and/or signs of liver dysfunction, it can be indicative of hepatic or biliary obstruction.
What’s Worse, Hepatitis A, B, or C?Because there is no vaccination available against hepatitis C, hepatitis C is often considered worse than hepatitis A or B.
