Chronic Hepatitis B Infection
What is Chronic Hepatitis B Infection?
Chronic Hepatitis B infection is a long-term viral illness that affects the liver. It happens when the Hepatitis B virus stays in your body for more than six months. Your immune system cannot clear the virus on its own.
The virus attacks liver cells and causes inflammation over time. This ongoing damage can lead to serious problems like cirrhosis or liver cancer. Many people with chronic Hepatitis B do not feel sick for years, even as the virus quietly harms their liver.
About 296 million people worldwide live with chronic Hepatitis B. The condition is manageable with proper care and monitoring. Regular blood tests help track the virus and protect your liver health.
Symptoms
- Fatigue and feeling tired for no clear reason
- Yellowing of skin and eyes, also called jaundice
- Dark-colored urine
- Pain or discomfort in the upper right abdomen
- Loss of appetite and unintended weight loss
- Nausea and vomiting
- Joint pain and muscle aches
- Fever and general feeling of being unwell
Many people with chronic Hepatitis B have no symptoms for years or even decades. The virus can silently damage your liver without obvious warning signs. This is why regular blood testing is essential for anyone at risk.

Causes and risk factors
Chronic Hepatitis B develops when the Hepatitis B virus enters your bloodstream and your immune system cannot eliminate it. The virus spreads through contact with infected blood or body fluids. Common ways people get infected include birth from an infected mother, unprotected sexual contact, sharing needles, and accidental needle sticks in healthcare settings. The virus does not spread through casual contact like hugging, sharing food, or coughing.
Your risk is higher if you were born in areas where Hepatitis B is common, including parts of Asia, Africa, and the Pacific Islands. Other risk factors include having multiple sexual partners, living with someone who has Hepatitis B, using injection drugs, working in healthcare, receiving dialysis, or having HIV. People infected as babies or young children are much more likely to develop chronic infection compared to adults. About 90% of infected infants become chronically infected, while only 5% of infected adults do.
How it's diagnosed
Doctors diagnose chronic Hepatitis B through blood tests that detect viral markers and antibodies. The Hepatitis B Surface Antigen test shows if the virus is currently in your body. If this marker stays positive for more than six months, it confirms chronic infection. Additional tests like Hepatitis B Core Antibody and Hepatitis Be Antibody help determine how active the infection is and whether your body is trying to fight it.
Rite Aid offers Hepatitis B testing as an add-on to our annual blood panel at Quest Diagnostics locations nationwide. Your doctor may also order liver function tests to check for damage and imaging studies like ultrasound to look at your liver. Regular monitoring helps track the virus and catch any problems early.
Treatment options
- Antiviral medications like tenofovir or entecavir to slow virus reproduction and reduce liver damage
- Regular blood tests every 3 to 6 months to monitor virus levels and liver function
- Avoid alcohol completely, as it speeds up liver damage
- Maintain a healthy weight through balanced nutrition and regular physical activity
- Get vaccinated against Hepatitis A to prevent additional liver stress
- Inform sexual partners and household contacts so they can get vaccinated
- Never share personal items like razors or toothbrushes that might have blood on them
- Talk to your doctor before taking any new medications or supplements, as some can harm the liver
- Consider liver imaging and screening for liver cancer if you have advanced disease

Frequently asked questions
Acute Hepatitis B is a short-term infection that lasts less than six months. Your immune system usually clears the virus on its own. Chronic Hepatitis B means the virus stays in your body for more than six months. Your immune system cannot eliminate it, and the infection can last for years or even a lifetime.
There is no cure that completely eliminates the virus in most cases. However, antiviral medications can control the virus and prevent liver damage. Some people achieve what doctors call a functional cure, where the virus becomes undetectable. Regular treatment and monitoring help most people live long, healthy lives with this condition.
Most people need blood tests every 3 to 6 months to monitor virus levels and liver health. Your doctor checks markers like Hepatitis B Surface Antigen and liver enzymes. If you are taking antiviral medication or have active liver disease, you may need testing more often. Regular monitoring catches problems early and guides treatment decisions.
Yes, the virus can spread through blood and body fluids, but casual contact is safe. Your family cannot get infected from hugging, kissing, sharing food, or being in the same room. The virus can spread through sexual contact, sharing personal items with blood on them, or from mother to baby during birth. All household members and sexual partners should get vaccinated for protection.
A positive Hepatitis B Surface Antigen test means the virus is currently in your body. If this test stays positive for more than six months, it confirms chronic infection. Your doctor will order additional tests to see how active the virus is and whether your liver is being damaged.
Yes, you can safely have a baby with proper medical care. Pregnant women with Hepatitis B can pass the virus to their baby during birth. Babies born to infected mothers need Hepatitis B vaccine and immune globulin within 12 hours of birth. These treatments prevent infection in more than 95% of cases.
Not everyone develops serious liver damage, but the risk is real without proper care. Some people carry the virus with minimal liver inflammation for decades. Others develop cirrhosis or liver cancer over time. Regular blood tests, antiviral treatment when needed, and healthy lifestyle choices significantly reduce your risk of serious complications.
No, you should avoid alcohol completely if you have chronic Hepatitis B. Alcohol speeds up liver damage and increases your risk of cirrhosis and liver cancer. Even small amounts of alcohol can harm your liver when combined with the virus. Talk to your doctor if you need help quitting.
Avoid alcohol completely to protect your liver. Maintain a healthy weight through nutritious eating and regular exercise, as excess weight can worsen liver damage. Get enough sleep and manage stress to support your immune system. Take all medications as prescribed and attend regular check-ups to monitor your condition.
