Keep reading for more on asymptomatic hepatitis B infections, how common they are, how the virus is transmitted, common symptoms, possible treatments, and prevention strategies.
What Is a Hepatitis B Carrier?
People who are called carriers of hepatitis B have a chronic (long-term) infection but don’t feel ill and don’t have any symptoms. Though a person who is a hepatitis B carrier has no symptoms, they can transmit the virus to other people.
How Common Are Hepatitis B Carriers?
Of all people with a hepatitis B infection, about 6% and up to 10% are considered carriers. Children may be more likely to be carriers. Around 90% of babies who become infected with the virus during birth are carriers. Further, about half of the children who become infected under the age of 5 become hepatitis B carriers.
How Is Hepatitis B Transmitted?
Hepatitis B is transmitted from one person to another due to contact with infected body fluids, primarily blood, and semen. Transmission can occur during the following:
Birth (from a birthing person to their baby)Sex with a person who is infectedUse of shared needlesUse of other personal items (such as razors and toothbrushes)Contact with open sores on a person who is infected
Preventing the Spread of Hepatitis B
One of the most important tools of prevention for hepatitis B is vaccination. The hepatitis B vaccines are recommended for infants through adults ages 60 and older who are not already infected.
Fever Fatigue Jaundice Pain in the abdomen or joints Nausea and vomiting Dark-colored urine Light-colored bowel movements
Avoiding contact with bodily fluids that could transmit the virus is also a key strategy for prevention. This includes using barrier methods during sex, not sharing personal items, and not sharing used needles.
Hepatitis B Diagnosis
Over half of the people living with a hepatitis B infection don’t know they are infected. A healthcare provider can give you a blood test to tell whether you have hepatitis B. Many people with hepatitis B find out they have the infection when they donate blood.
Treatment
Treatment will depend on whether the infection you have is acute or chronic. A healthcare provider may not treat acute hepatitis infections other than by managing symptoms. Often, your healthcare provider will recommend that you get enough sleep, fluids, and nutritious foods in your meals to help you feel better. It’s also possible that an acute infection will go on its own.
People born in countries that have a prevalence rate of the virus that’s greater than 2%People who were unvaccinated as babies and had parents that came from countries with a higher prevalence of hepatitis BMen who have sex with menPeople who use injectable drugsPeople living with HIV, diabetes, or end-stage kidney failurePeople who live with or have had sex with someone who has hepatitis BPeople who are on immunosuppressive therapyBabies born to someone who has hepatitis B
If your body doesn’t clear the infection, it can result in chronic infection. A healthcare provider may prescribe an antiviral medication to treat chronic infection, but not everyone with a chronic infection needs to be treated. There is not yet a cure for hepatitis B, but the treatment helps to suppress the virus in the body and reduces the risk of liver damage and liver cancer.
Summary
Hepatitis B can cause acute or chronic infections that may result in liver damage, scarring, or cancer. In the course of a chronic infection, some people may not have any symptoms or feel sick. They are referred to as carriers and they can infect other people. Between 6% and 10% of people who have a hepatitis B infection are considered carriers.
The hepatitis B virus is transmitted through contact with bodily fluids, primarily the blood and semen of someone infected. A healthcare provider can diagnose a hepatitis B infection through a blood test. Acute infections may not be treated, but antiviral medications may be prescribed to people with chronic infections. Vaccination is a top prevention strategy, along with avoiding contact with bodily fluids that may transmit the virus.
A Word From Verywell
Like many other infections, hepatitis B is a virus that many people have but don’t know it. Getting vaccinated against the virus is one of the best strategies for prevention. Further, understanding the factors that increase your risk for infection can help you discuss when and if you should be tested for hepatitis B. Knowing your (positive or negative) status will help you make decisions about how to prevent infection in others and get timely treatment to reduce the risk of liver damage.
