Hepatitis B vs Hepatitis C: Symptoms, Transmission, Testing & Treatment

Hepatitis B and Hepatitis C are viral infections that affect the liver. Although they can cause similar liver problems, they are caused by different viruses and differ in how they spread, how they are prevented and how they are treated.

One of the biggest challenges is that many people with chronic hepatitis B or hepatitis C may have no obvious symptoms for years.

During this time, ongoing infection can potentially damage the liver.

Understanding the differences between Hepatitis B (HBV) and Hepatitis C (HCV) can help people recognise risk factors, seek appropriate testing and access treatment when needed.

What Is Viral Hepatitis?

Hepatitis means inflammation of the liver.

The liver performs many essential functions, including processing nutrients, helping remove harmful substances from the blood and producing proteins needed by the body.

Several viruses can cause viral hepatitis.

The major types include:

• Hepatitis A
• Hepatitis B
• Hepatitis C
• Hepatitis D
• Hepatitis E

Hepatitis B and C are particularly important because both can develop into chronic infections and cause long-term liver damage.

What Is Hepatitis B?

Hepatitis B is a liver infection caused by the hepatitis B virus (HBV).

HBV infection may be acute or chronic.

An acute infection occurs during the initial period after acquiring the virus. Many adults are able to clear an acute HBV infection naturally.

However, some people develop chronic hepatitis B, meaning the infection remains in the body.

The likelihood of developing chronic infection is much higher when HBV is acquired during infancy or early childhood.

What Is Hepatitis C?

Hepatitis C is caused by the hepatitis C virus (HCV).

Like hepatitis B, HCV initially causes an acute infection.

Some people clear the virus naturally, but many untreated infections become chronic.

Chronic hepatitis C can gradually damage the liver and may eventually lead to complications such as cirrhosis or liver cancer.

The major difference today is that modern antiviral medicines can cure most people with hepatitis C.

Hepatitis B vs Hepatitis C: What’s the Difference?

Although both infections affect the liver, there are several important differences.

These differences make accurate diagnosis particularly important.

How Is Hepatitis B Transmitted?

HBV can spread through infected blood and certain body fluids.

Transmission may occur through:

• Birth from a mother with HBV to her baby
• Sexual contact
• Sharing needles or injection equipment
• Exposure to infected blood
• Sharing certain personal items contaminated with blood
• Unsafe medical or tattooing equipment

HBV is not normally spread through casual everyday contact such as hugging, coughing or sharing a meal.

How Is Hepatitis C Transmitted?

Hepatitis C primarily spreads through blood-to-blood contact.

Potential routes include:

• Sharing needles or injection equipment
• Unsafe medical procedures
• Blood transfusions performed in settings or periods where adequate screening was unavailable
• Needlestick injuries
• Unsterile tattoo or piercing equipment
• Sharing personal items contaminated with blood

Sexual transmission can occur, although the likelihood varies depending on circumstances.

HCV can also be transmitted from mother to baby during pregnancy or childbirth.

What Are the Symptoms of Hepatitis B and C?

Many people with hepatitis B or hepatitis C experience no symptoms, particularly during chronic infection.

When symptoms do occur, they may include:

• Fatigue
• Fever
• Loss of appetite
• Nausea
• Vomiting
• Abdominal discomfort
• Joint pain
• Dark urine
• Pale or clay-coloured stools
• Yellowing of the skin or eyes (jaundice)

These symptoms are not specific to viral hepatitis.

Blood tests are required to determine whether HBV or HCV infection is present.

Why Can Hepatitis Remain Undetected?

Chronic viral hepatitis can sometimes be described as a “silent” infection because significant liver damage may develop without obvious symptoms.

A person may feel healthy even while inflammation or scarring is occurring in the liver.

This is why testing can be important for people with relevant risk factors or those for whom screening is recommended.

How Is Hepatitis B Diagnosed?

Hepatitis B is diagnosed using blood tests.

Several HBV markers may be measured because each provides different information.

These can include:

HBsAg

Hepatitis B surface antigen (HBsAg) can indicate a current HBV infection.

Anti-HBs

Hepatitis B surface antibody (anti-HBs) may indicate immunity following vaccination or recovery from infection.

Anti-HBc

Hepatitis B core antibody (anti-HBc) indicates previous or ongoing exposure to HBV and is not produced by vaccination alone.

HBV DNA

An HBV DNA test measures the amount of hepatitis B virus in the blood.

It can help doctors assess viral replication and monitor treatment in appropriate patients.

Because HBV blood-test interpretation can be complex, results should be reviewed by a qualified healthcare professional.

How Is Hepatitis C Diagnosed?

Testing for hepatitis C commonly involves more than one step.

HCV Antibody Test

The first test often checks for antibodies against hepatitis C.

A reactive antibody test indicates that a person has been exposed to HCV at some point.

It does not necessarily mean the virus is still present.

HCV RNA Test

If the antibody test is reactive, an HCV RNA test can determine whether hepatitis C virus is currently present in the blood.

This confirms an active infection.

Can Hepatitis B Be Cured?

Chronic hepatitis B can be effectively managed, but currently available treatments do not routinely eliminate the virus completely.

Antiviral medicines can suppress HBV replication and reduce the risk of liver damage in people who meet treatment criteria.

Not everyone with chronic HBV needs antiviral treatment immediately.

Some people require regular monitoring instead.

Doctors may consider factors such as:

• HBV DNA level
• Liver enzyme levels
• Degree of liver damage
• Age
• Other medical conditions
• Family and clinical history

Regular monitoring remains important even when treatment is not currently required.

Can Hepatitis C Be Cured?

Yes.

Modern medicines known as direct-acting antivirals (DAAs) can cure most people with hepatitis C.

Treatment commonly involves oral medication for a defined period, often approximately 8–12 weeks, although the regimen and duration depend on individual circumstances.

A successful cure is generally confirmed when HCV RNA remains undetectable after the appropriate period following completion of treatment.

Is There a Vaccine for Hepatitis B?

Yes.

A highly effective hepatitis B vaccine is available and is an important method of preventing HBV infection.

Vaccination is particularly important as part of routine immunisation programs and for people who may have increased exposure risk.

Healthcare professionals can determine whether vaccination or additional testing is appropriate.

Is There a Vaccine for Hepatitis C?

Currently, there is no approved vaccine for hepatitis C.

Prevention therefore focuses on reducing exposure to infected blood and identifying and treating people who have HCV.

What Happens If Hepatitis B or C Is Left Untreated?

Chronic viral hepatitis can cause persistent inflammation in the liver.

Over time, this may lead to fibrosis, which means scar tissue begins forming.

Advanced scarring is known as cirrhosis.

Possible long-term complications include:

• Cirrhosis
• Liver failure
• Portal hypertension
• Liver cancer
• Other complications of advanced liver disease

Not every person with chronic hepatitis develops these complications, but appropriate monitoring and treatment can substantially reduce risk.

Hepatitis and Liver Cancer

Both chronic hepatitis B and chronic hepatitis C can increase the risk of hepatocellular carcinoma, the most common form of primary liver cancer.

The level of risk varies according to the individual and the extent of liver disease.

Some patients with chronic viral hepatitis require regular liver cancer surveillance.

A healthcare professional can determine whether surveillance is appropriate and how often it should be performed.

How Can Hepatitis B and C Be Prevented?

Prevention strategies include:

• Receiving hepatitis B vaccination when appropriate
• Never sharing needles or injection equipment
• Using sterile equipment for tattoos and piercings
• Following safe medical injection practices
• Avoiding sharing razors or toothbrushes that may contain blood
• Using appropriate protection when there is a risk of sexual transmission
• Testing during pregnancy according to medical guidance
• Following appropriate blood-screening practices

Testing and treating infections also play an important role in reducing transmission.

Frequently Asked Questions

Which is more serious: Hepatitis B or Hepatitis C?

Both can cause serious chronic liver disease. The individual risk depends on factors including duration of infection, viral activity, liver damage and other health conditions.

Which hepatitis has a vaccine?

A vaccine is available for hepatitis B. There is currently no approved hepatitis C vaccine.

Is Hepatitis C completely curable?

Modern direct-acting antiviral medicines can cure most people with hepatitis C.

Is chronic Hepatitis B curable?

Current treatments can suppress chronic HBV very effectively, but a routine complete cure is not currently available for most patients.

Can Hepatitis B and C cause liver cancer?

Yes. Chronic HBV and HCV infections can increase the risk of liver cancer.

Can someone have hepatitis without symptoms?

Yes. Both infections can remain asymptomatic for years, which is why testing is important when appropriate.

Can Hepatitis B spread by sharing food?

HBV is not generally transmitted by sharing meals, hugging, coughing or other ordinary casual contact.

When Should You Consider Hepatitis Testing?

Testing may be appropriate based on medical history, pregnancy, potential blood exposure, previous medical procedures, injection-drug exposure, sexual exposure, country or region of birth, or other clinical risk factors.

Screening recommendations can vary by age, country and individual circumstances.

A healthcare professional can recommend the appropriate HBV or HCV tests.

Conclusion

Hepatitis B and Hepatitis C are different viral infections that can both cause chronic liver disease.

Hepatitis B can be prevented with vaccination and can often be effectively controlled with antiviral treatment when treatment is needed.

Hepatitis C currently has no vaccine, but modern direct-acting antiviral medicines can cure most infections.

Because both infections can remain silent for years, appropriate testing is one of the most important steps toward preventing serious liver complications.
