World Hepatitis Day (WHD) 2025: Uniting in the Fight Against a Global Health Threat

Viral hepatitis is one of the most widespread and serious infectious diseases, affecting millions of people around the world, often going undetected until it causes significant liver damage. Despite its high burden, public awareness around the condition is still limited. To address this gap, World Hepatitis Day is observed every year on 28th of July, aiming to raise awareness, encourage testing, and promote prevention and treatment. In line with this goal, this blog aims to shed light on the disease, covering its symptoms, causes, and treatment. Let us begin with how World Hepatitis Day came into being and why it continues to be important.

History and Significance of World Hepatitis Day

World Hepatitis Day is observed every year on 28 July to raise global awareness about viral hepatitis and the urgent need to prevent, diagnose, and treat the condition. The date marks the birth anniversary of Dr Baruch Blumberg, who discovered the Hepatitis B virus and developed the first vaccine for it. His contribution laid the foundation for major breakthroughs in hepatitis research and prevention.

The World Health Organization officially recognised the day in 2010, aiming to draw attention to the millions of people living with hepatitis who remain undiagnosed and untreated. Over the years, World Hepatitis Day has helped governments, health bodies, and communities worldwide to highlight the disease burden, promote testing, improve access to care, and work towards the global goal of eliminating viral hepatitis as a public health threat by 2030.

What is Viral Hepatitis?

The liver plays a vital role in filtering toxins, processing nutrients, and supporting overall health. When a viral infection causes inflammation in this organ, it disrupts these essential functions and places strain on the entire body. Viral hepatitis refers specifically to liver inflammation caused by certain viruses that target the liver directly. The infection may be mild in some cases, but in others, it can progress silently for years and cause lasting damage.

What makes viral hepatitis especially concerning is that many infected individuals do not show symptoms until the liver is already significantly affected. This silent progression often delays diagnosis and increases the risk of complications.

What Are the Different Types of Viral Hepatitis?

Viral hepatitis is classified into five main types: Hepatitis A, B, C, D, and E. Each type is caused by a different virus and has its own way of spreading, affecting the liver, and progressing over time.

• Hepatitis A: Usually spreads through contaminated food or water. It causes a short-term infection and does not lead to long-term liver problems in most cases.
• Hepatitis B: Transmitted through blood, unprotected sex, or from mother to baby during birth. It can lead to chronic infection and increase the risk of liver cirrhosis or liver cancer.
• Hepatitis C: Mainly spreads through contact with infected blood, often through unsafe medical procedures or sharing of needles. It often becomes chronic and may cause serious liver damage over time.
• Hepatitis D: Only occurs in people who are already infected with Hepatitis B. It can make the infection more severe and harder to treat.
• Hepatitis E: Similar to Hepatitis A, it spreads through contaminated water. It usually causes a short-term infection but can be more dangerous during pregnancy.

Each type of hepatitis varies in its symptoms, duration, and outcomes. Some are preventable through vaccination, and others can be treated effectively if detected early. 

What are the Symptoms of Viral Hepatitis?

The symptoms of viral hepatitis can range from mild to severe, and in many cases, there may be no symptoms at all, especially in the early stages. When symptoms do appear, they often resemble those of common viral illnesses, which can make the infection harder to detect without testing.

Common signs of viral hepatitis include:

• Tiredness or weakness
• Loss of appetite
• Fever
• Nausea or vomiting
• Abdominal pain, especially near the liver (right upper side)
• Dark-coloured urine
• Pale stools
• Yellowing of the skin and eyes (jaundice)

In some cases, these symptoms may appear suddenly and last a few weeks, or they may develop slowly and persist for months if the infection becomes chronic. 

How Does Viral Hepatitis Spread?

Viral hepatitis can spread through several routes, depending on the specific virus. Some types are transmitted through contaminated food or water, while others spread through blood and body fluids. The risk of infection often increases in settings with poor sanitation, unsafe medical practices, or lack of awareness about prevention methods.

Hepatitis A and E are typically spread through the faecal-oral route, which means a person can become infected by consuming food or water that has been contaminated with the faeces of someone who has the virus. This is more common in areas with limited access to clean drinking water and proper sanitation. Eating raw or undercooked shellfish from contaminated water can also increase the risk.

Hepatitis B, C, and D mainly spread through contact with infected blood or other body fluids. Common ways this can happen include:

• Sharing needles or syringes, especially among people who inject drugs
• Receiving contaminated blood products or undergoing medical procedures with unsterile equipment
• Unprotected sexual contact with an infected person, particularly in the case of Hepatitis B
• From mother to baby during childbirth, especially in the case of Hepatitis B
• Sharing personal items like razors or toothbrushes that may have traces of infected blood

Hepatitis D is unique because it only occurs in individuals who are already infected with Hepatitis B, and it shares the same modes of transmission.

Some forms of hepatitis can also spread within households or through close contact, although this is less common. It is important to remember that hepatitis cannot spread through casual contact such as hugging, kissing, or sharing meals.

How is Hepatitis Diagnosed?

Diagnosing hepatitis involves several steps that help identify the type of virus involved, assess the extent of liver involvement, and determine whether the infection is acute or chronic. Since symptoms are often mild or absent in the early stages, testing is key to detecting the infection before serious damage occurs.

Medical History and Risk Assessment

The process usually begins with a discussion about possible risk factors. Doctors often ask about recent travel to areas with poor sanitation, consumption of unsafe food or water, history of injecting drug use, sexual activity, past medical procedures, or blood transfusions. They may also inquire about exposure to someone known to have hepatitis or if the person works in a healthcare setting. This helps identify the most likely type of hepatitis and guides the next steps in diagnosis.

Physical Examination

A physical examination may follow, focusing on signs that suggest liver involvement. These can include yellowing of the skin or eyes, pain or tenderness in the upper right side of the abdomen, or signs of fluid buildup. However, many individuals may not show visible symptoms, especially in the early stages, making laboratory tests an essential part of the diagnosis.

Blood Tests

Blood tests are the most important part of diagnosing hepatitis. These tests check for the presence of specific viruses and measure how well the liver is functioning. Liver enzymes such as ALT and AST are commonly checked to detect inflammation. Additional blood tests may look for antibodies or viral genetic material, which help confirm the type of hepatitis and whether the infection is recent or long-standing.

Imaging Tests

If blood test results suggest liver damage, imaging tests may be recommended. An ultrasound can reveal signs such as liver enlargement, fatty deposits, or fluid accumulation. In people with long-term hepatitis, a fibroscan may be used to measure liver stiffness, which helps detect fibrosis or cirrhosis without the need for invasive procedures.

Liver Biopsy

In some cases, a liver biopsy may be required to better understand the condition of the liver. A small tissue sample is taken and examined under a microscope. This helps doctors assess the extent of inflammation or scarring and decide on the most suitable treatment approach, especially in chronic cases or when imaging results are unclear.

Diagnosis plays a crucial role in the management of hepatitis, as early detection not only improves treatment outcomes but also helps prevent the spread of the infection to others.

What are the Treatment Options?

The approach to treating viral hepatitis depends on the type of virus, how advanced the infection is, and the condition of the liver. Some types are clear on their own with basic care, while others require long-term treatment to manage the virus and prevent serious complications.

Treatment for Acute Hepatitis

In most cases of acute hepatitis, such as Hepatitis A and E, the infection is short-lived and does not require specific antiviral medicines. Treatment focuses on supportive care to help the liver recover. This includes plenty of rest, a balanced diet, and staying well-hydrated. Medicines may be used to relieve symptoms such as fever or nausea, but hospitalisation is rarely needed unless symptoms are severe or complications arise. With proper care, full recovery usually occurs within a few weeks to months.

Treatment for Chronic Hepatitis B

Chronic Hepatitis B cannot be cured completely in most cases, but antiviral medicines can help keep the virus under control. These medicines reduce the amount of virus in the body, lower the risk of liver scarring (fibrosis), and help prevent liver failure or cancer. Treatment is often long-term and requires regular monitoring to assess how the liver is responding and to adjust the plan if needed. In some cases, treatment may not start right away but is recommended based on liver function tests and the amount of virus in the blood.

Treatment for Chronic Hepatitis C

Chronic Hepatitis C is now one of the most treatable forms of viral hepatitis. The most effective treatment is a group of medicines known as direct-acting antivirals (DAAs). These are taken for a few weeks to a few months, depending on the case. In most people, DAAs can completely clear the virus from the body, greatly reducing the risk of future liver problems. Regular follow-up is still important after treatment to make sure the liver remains healthy and no complications develop later.

Treatment for Hepatitis D

Hepatitis D only occurs in people who already have Hepatitis B. It is more difficult to treat and often requires a specialist’s care. In some cases, medicines used for Hepatitis B may help manage Hepatitis D, but the response to treatment is often less predictable. Newer treatments are being studied, but availability may vary.

How Can Hepatitis Be Prevented?

Preventing hepatitis involves a mix of safe practices, improved hygiene, vaccination, and public awareness. Since each type of viral hepatitis spreads in different ways, prevention strategies vary, but they all focus on stopping transmission and protecting liver health.

Vaccination

Vaccines are available for Hepatitis A and B and are highly effective. These vaccines not only protect individuals but also help reduce the spread of infection in the wider community. In many countries, Hepatitis B vaccination is included in the national immunisation schedule, and a combined Hepatitis A and B vaccine is also available.

Although there is no vaccine yet for Hepatitis C or D, preventing Hepatitis B can also reduce the risk of Hepatitis D, as the latter only occurs in people who already have Hepatitis B. Research is ongoing for a vaccine against Hepatitis C.

Safe Food and Water

To prevent Hepatitis A and E, which spread through contaminated food and water, it is important to practise proper hygiene and food safety. Drinking clean, boiled, or filtered water, eating food that is properly cooked, and washing hands before meals and after using the toilet can greatly lower the risk of infection. These measures are especially important in areas with poor sanitation.

Avoiding Contact with Infected Blood and Body Fluids

For Hepatitis B, C, and D, avoiding direct contact with infected blood or body fluids is essential. This includes:

• Not sharing needles, syringes, or any sharp objects
• Ensuring medical equipment is sterile and properly handled
• Choosing licensed blood banks for transfusions
• Using barrier protection during sexual activity, such as condoms
• Avoiding the sharing of personal items like razors or toothbrushes

Safe medical and dental practices and regular screening in high-risk groups also help reduce the spread of infection.

Preventing Transmission from Mother to Baby

Hepatitis B can be passed from an infected mother to her baby during childbirth. This risk can be reduced with proper medical care. Pregnant women should be screened for Hepatitis B during prenatal check-ups. If the infection is present, the newborn should receive a dose of the Hepatitis B vaccine and hepatitis B immunoglobulin (HBIG) within 12 hours of birth. These measures significantly lower the chances of the baby developing a chronic infection.

How Can You Contribute This World Hepatitis Day?

World Hepatitis Day serves as a reminder that individual actions can support the global effort to eliminate viral hepatitis. Several simple but meaningful steps can help prevent the spread of infection and reduce the burden of liver disease.

• Get tested if at risk: Testing is important for those who may have been exposed through blood contact, unprotected sex, unsafe injections, or past medical procedures. Early diagnosis helps prevent complications and limits further spread.
• Encourage others to get tested: Talking to family or friends about hepatitis and encouraging them to get screened can help uncover silent infections and reduce stigma around the condition.
• Get vaccinated: Hepatitis B vaccination is available and effective. Those who are not vaccinated, especially children and people in high-risk settings, should consider getting immunised. In some cases, the Hepatitis A vaccine may also be recommended.
• Share accurate information: Raising awareness through reliable sources helps counter myths and supports early prevention. This could include sharing articles, attending local events, or posting informative messages on social media.
• Support safe practices in daily life: Avoid sharing sharp items such as razors or toothbrushes. Always use sterile equipment for medical or cosmetic procedures and practise safe sex to reduce the risk of transmission.
• Advocate for better public health measures: Supporting access to clean water, proper sanitation, and safe healthcare helps lower the spread of hepatitis, especially in underserved areas.
