World Hepatitis Day: Your Guide to the 5 Types of Hepatitis

Every year on 28 July, World Hepatitis Day shines a spotlight on one of the world’s most significant yet often preventable public health challenges. Hepatitis is endemic in many developing regions, including parts of Africa, where approximately 70% of chronic cases are found. Millions of people globally are living with viral hepatitis, many without even knowing it. In Southern Africa, hepatitis remains an important public health concern, with hepatitis B and hepatitis C continuing to contribute to chronic liver disease, cirrhosis and liver cancer.

Despite its impact, there is still widespread confusion about what hepatitis is, how it spreads and whether it can be treated. Understanding the different types of hepatitis is an important step towards protecting your health and reducing the risk of long-term liver damage.

What Is Hepatitis?

Hepatitis refers to inflammation of the liver. The liver performs hundreds of essential functions, including filtering toxins from the blood, storing nutrients, producing proteins and helping the body digest food. It is also responsible for producing clotting factors that are essential in preventing excessive bleeding and supporting normal blood clot formation.

When the liver becomes inflamed, its ability to perform these functions can be affected. In some cases, hepatitis is mild and resolves on its own. In others, it can become chronic or progress rapidly into acute, fulminant disease, which may lead to liver failure, hepatic encephalopathy and, in severe cases, death.

While viral infections are the most common cause of hepatitis worldwide, liver inflammation can also be caused by other microorganisms as well as metabolic conditions. Additional causes include excessive alcohol consumption, autoimmune conditions, certain medications and exposure to toxins.

The five main types of viral hepatitis are hepatitis A, hepatitis B, hepatitis C, hepatitis D and hepatitis E.

Hepatitis A

Hepatitis A is caused by the hepatitis A virus and primarily affects the liver for a short period. Unlike some other forms of hepatitis, hepatitis A does not usually cause chronic infection.

The virus is most commonly spread through contaminated food or water and poor sanitation. This means outbreaks can occur in areas where access to clean water and proper hygiene practices may be limited. Some people, particularly children, may show no symptoms at all but can still spread the virus through their stool to others who are not vaccinated. In symptomatic cases, individuals may also experience acute watery diarrhoea and vomiting.

Symptoms may include fatigue, nausea, abdominal discomfort, fever, loss of appetite, dark urine and jaundice, which causes yellowing of the skin and eyes.

Most people recover fully from hepatitis A without lasting liver damage. Vaccinations are available and remain one of the most effective ways to prevent infection.

Hepatitis B

Hepatitis B is one of the most common forms of viral hepatitis worldwide and remains a major public health concern, particularly in many African countries where chronic hepatitis B is highly prevalent.

The hepatitis B virus is transmitted through contact with infected blood and bodily fluids. Transmission can occur from mother to child during childbirth, through unprotected sexual contact, sharing needles or exposure to contaminated medical equipment.

Some people develop an acute infection and recover completely. However, others develop chronic hepatitis B, meaning the virus remains in the body for more than six months. Chronic infection is associated with ongoing liver inflammation and damage, increasing the risk of serious complications such as cirrhosis and liver cancer.

One of the challenges associated with hepatitis B is that many individuals experience few or no symptoms during the early stages of infection. As a result, people may unknowingly carry the virus for years before complications develop.

Fortunately, many people with chronic hepatitis B can live long, healthy lives with appropriate medical care, regular monitoring and treatment when required. Early diagnosis is critical in reducing the risk of liver damage and preventing transmission to others.

Vaccination against hepatitis B is highly effective and forms part of routine childhood immunisation programmes in many countries, including South Africa. Vaccination is also strongly recommended for people at increased risk of exposure, such as healthcare workers. In addition, testing all pregnant women for hepatitis B is an important strategy for reducing mother-to-child transmission. This is particularly important because infants infected during childbirth are at a much higher risk of developing chronic hepatitis B, which significantly increases their lifetime risk of liver cancer.

Hepatitis C

Hepatitis C is caused by the hepatitis C virus and is primarily transmitted through contact with infected blood. Transmission can occur through sharing needles, exposure to contaminated blood or medical equipment and, less commonly, through unprotected sexual contact or from mother to child during pregnancy or childbirth.

Historically, transmission sometimes occurred through unscreened blood transfusions. Today, improved blood screening practices have significantly reduced this risk.

Like hepatitis B, hepatitis C may not cause noticeable symptoms for many years. Some individuals only discover they have the infection when liver damage is detected during routine medical testing.

Untreated chronic hepatitis C can lead to cirrhosis, liver failure and liver cancer. Fortunately, modern antiviral medications have transformed the outlook for many patients. In many cases, treatment can successfully eliminate the virus from the body, making early testing and diagnosis especially important.

Unlike hepatitis A and hepatitis B, there is currently no vaccine available to prevent hepatitis C. Prevention therefore relies on reducing the risk of exposure through measures such as screening donated blood, practising safer sex, avoiding the sharing of needles and ensuring that medical equipment is sterile or single-use.

Hepatitis D

Hepatitis D is less common but can be particularly serious. The hepatitis D virus is unique because it can only infect individuals who already have hepatitis B. For this reason, hepatitis D is sometimes referred to as a “satellite virus.”

People living with both hepatitis B and hepatitis D may experience more severe liver disease and face a higher risk of complications than those with hepatitis B alone.

Preventing hepatitis B through vaccination is one of the most effective ways to prevent hepatitis D infection.

Hepatitis E

Hepatitis E is another viral infection that primarily spreads through contaminated food and water. It is most common in regions with limited access to clean sanitation systems and safe drinking water. Like hepatitis A, hepatitis E generally causes an acute infection rather than a chronic illness.

Most people recover fully without long-term complications. However, hepatitis E can be particularly dangerous for pregnant women, who may face a higher risk of severe illness.

Preventing hepatitis E relies on good hygiene and safe water practices. Treating drinking water by boiling it or using an appropriate hypochlorite solution, practising proper handwashing and following food safety guidelines can all help reduce the risk of infection.

What Are the Signs of Hepatitis?

One of the reasons hepatitis is sometimes called a “silent disease” is that symptoms may be mild or absent, particularly during the early stages.

When symptoms do occur, they often develop gradually and can resemble other common illnesses.

Common hepatitis symptoms may include:

• Persistent fatigue
• Fever
• Loss of appetite
• Nausea and vomiting
• Abdominal pain or discomfort
• Dark-coloured urine
• Pale stools
• Joint pain
• Jaundice (yellowing of the skin and eyes)
• In the case of hepatitis A and E, diarrhoea 

The presence and severity of symptoms can vary depending on the type of hepatitis and whether the infection is acute or chronic.

Anyone experiencing ongoing symptoms or signs of liver disease should seek medical assessment as soon as possible.

How Is Hepatitis Transmitted?

Different types of hepatitis spread in different ways.

Hepatitis A and hepatitis E are most commonly transmitted through contaminated food and water. In some settings, transmission may also occur via flies that contaminate food, while certain sexual practices, including oro-anal contact, can also increase the risk of infection.

Hepatitis B, hepatitis C and hepatitis D are generally spread through contact with infected blood or bodily fluids. This can occur through unprotected sexual contact, sharing needles, unsafe medical procedures or transmission from mother to child during pregnancy or childbirth.

Understanding how hepatitis is transmitted is an important part of prevention. Vaccination, safe healthcare practices, safer sexual practices, good hygiene and access to clean food and water all play important roles in reducing the spread of infection.

Alcoholic Hepatitis and Autoimmune Hepatitis

Not all hepatitis is caused by viruses.

Alcoholic hepatitis develops as a result of excessive alcohol consumption, which damages liver tissue and causes inflammation. Symptoms can range from mild liver irritation to severe liver disease. Limiting alcohol intake or avoiding alcohol altogether can help reduce the risk of developing alcohol-related liver disease. People who consume alcohol regularly should also consider having their liver function monitored through routine medical check-ups.

Autoimmune hepatitis occurs when the body’s immune system mistakenly attacks healthy liver cells. The exact cause is not fully understood, but genetic and environmental factors are believed to play a role.

Both conditions require medical evaluation and treatment, but their causes, progression and management differ significantly from viral hepatitis.

Hepatitis Treatment: Can Hepatitis Be Cured?

The answer depends on the type of hepatitis involved.

Hepatitis A and hepatitis E generally resolve on their own with supportive care, rest and adequate hydration.

Hepatitis B cannot currently be cured in most cases, but it can often be successfully managed with antiviral medications and regular monitoring. Many people with chronic hepatitis B live long and healthy lives when their condition is properly managed.

Hepatitis C represents one of the greatest success stories in modern medicine. Advances in antiviral therapy mean that many patients can now be cured after completing treatment.

Treatment for hepatitis D often focuses on managing the infection and reducing liver damage, while autoimmune hepatitis may require medications that suppress immune system activity.

The most important factor is early diagnosis. The sooner hepatitis is detected, the better the chances of preventing long-term complications.

Preventing Hepatitis in Southern Africa

Prevention remains one of the most effective tools in the fight against hepatitis.

Individuals can reduce their risk by:

• Receiving recommended vaccinations, particularly for hepatitis A and hepatitis B
• Practising good hand hygiene
• Drinking safe, clean water
• Following food safety guidelines
• Avoiding the sharing of needles or personal items that may be contaminated with blood
• Practising safer sex
• Attending regular health screenings when at increased risk

Increasing awareness, improving access to testing and encouraging vaccination are essential components of reducing the burden of hepatitis across Southern Africa.

World Hepatitis Day: Why Awareness Matters

World Hepatitis Day serves as an important reminder that hepatitis remains a major global health concern. While significant progress has been made in prevention, diagnosis and treatment, many people continue to live with hepatitis without knowing it.

Raising awareness helps individuals recognise symptoms, understand risk factors and seek appropriate medical care when needed.
