What is Viral Hepatitis?
Viral hepatitis is an inflammation of the liver caused by a viral infection. The liver is a vital organ responsible for filtering toxins from the blood, aiding in digestion, and storing nutrients. When it's inflamed, its function can be impaired, sometimes leading to severe health complications or even liver failure.
According to the World Health Organisation (WHO), over 300 million people worldwide are living with chronic viral hepatitis, and many are unaware of it. If left undiagnosed or untreated, viral hepatitis can lead to over a million deaths each year. However, hepatitis is preventable, treatable, and in many cases curable. It is always advisable to undergo early diagnosis for effective treatment.
Depending on the transmission, the severity of illness it causes, and how it can be treated or prevented, there are five main types of viruses that cause viral hepatitis: Hepatitis A, B, C, D, and E.
What are the Different Types of Hepatitis?
Each type of hepatitis is caused by a different virus and has its own mode of transmission, symptoms, and treatment approach. Here are the different types of hepatitis:
Hepatitis A
Hepatitis A is an acute liver infection spread through contaminated food and water or close contact with an infected person. It doesn’t lead to chronic infection and is preventable through vaccination.
Hepatitis B
This type is transmitted through contact with infectious body fluids, such as blood or sexual fluids. Hepatitis B can be both acute and chronic. Chronic cases can lead to severe complications, but there is an effective vaccine available.
Hepatitis C
Often referred to as a "silent" disease, hepatitis C spreads primarily through blood-to-blood contact. It frequently leads to chronic infection and is a major cause of liver cancer. While there is no vaccine, highly effective treatments are available.
Hepatitis D
Hepatitis D occurs only in people infected with hepatitis B, as it needs the HBV virus to replicate. It is transmitted through contact with infectious blood. Preventing hepatitis B also prevents hepatitis D.
Hepatitis E
This type is transmitted mainly through contaminated water and is most prevalent in regions with poor sanitation. It usually causes acute infection and is particularly dangerous for pregnant women.
World Hepatitis Day 2025 Theme
World Hepatitis Day 2025 is observed globally with a new theme each year to focus efforts and messaging. The World Hepatitis Day theme for 2025 is “Hepatitis: Let's Break It Down”
The theme highlights the urgent need to remove financial, social, and systemic obstacles, including stigma, that stand in the way of eliminating hepatitis and preventing liver cancer.
History of World Hepatitis Day (WHD)
World Hepatitis Day (WHD) was established to raise global awareness about viral hepatitis and to encourage efforts toward its prevention, diagnosis, and treatment. The day is observed annually on July 28, chosen to honour the birthday of Dr. Baruch Blumberg, the scientist who discovered the hepatitis B virus and developed the first hepatitis B vaccine.
The first World Hepatitis Day was organised in 2008 by the World Hepatitis Alliance in partnership with the World Health Organisation (WHO). Since then, it has grown into a global movement with governments, health organisations, and communities worldwide coming together to promote education and action against hepatitis.
Over the years, World Hepatitis Day has played a crucial role in bringing attention to the burden of hepatitis, advocating for better healthcare policies, and pushing for increased access to vaccines and treatments. It continues to be a vital platform to unite people worldwide in the fight against viral hepatitis and its complications, such as liver cancer.
Importance and Significance of World Hepatitis Day (WHD)
World Hepatitis Day (WHD) plays a crucial role in global health by drawing attention to viral hepatitis, a disease that often remains unnoticed but affects hundreds of millions worldwide. The day is important because it helps increase public awareness, reduces stigma, and promotes education about the disease.
Many people living with hepatitis are unaware of their condition, which allows the virus to silently damage their liver over time. By observing World Hepatitis Day, health organizations and communities educate people about what hepatitis is, its symptoms, modes of transmission, and the importance of early testing and treatment.
WHD also serves as a platform to advocate for stronger healthcare policies, better access to vaccines, affordable treatments, and improved screening programs. It encourages governments and international bodies to prioritise hepatitis elimination as a public health goal.
Stigma and misinformation often prevent people from seeking testing and treatment. World Hepatitis Day helps challenge misconceptions, encouraging empathy and support for those affected.
World Hepatitis Day is significant because it unites the global community in the fight against hepatitis, promoting prevention, early diagnosis, and access to life-saving care, bringing us closer to a future free of hepatitis-related illness and death.
Who is at Risk for Hepatitis?
While hepatitis can affect anyone, certain groups of people are at higher risk of contracting the disease due to their lifestyle, environment, or medical history. Here are some high-risk individuals who can:
High-Risk Groups Include:
People Who Inject Drugs: Sharing needles or other drug paraphernalia can easily transmit hepatitis B and C viruses through infected blood.
Healthcare Workers: Frequent exposure to blood and bodily fluids increases the risk of accidental infection if proper precautions are not taken.
Individuals with Multiple Sexual Partners: Unprotected sex increases the chance of transmitting hepatitis B and, to a lesser extent, hepatitis C.
Infants Born to Infected Mothers: Hepatitis B can be passed from mother to baby during childbirth if preventive measures aren’t in place.
People Receiving Blood Transfusions or Organ Transplants: Especially in areas where blood screening is inadequate.
Residents or Travelers in Areas with Poor Sanitation: Exposure to contaminated food and water can lead to hepatitis A and E infections.
People with Tattoos or Piercings Done in Unregulated Settings: Using non-sterile equipment can expose individuals to hepatitis viruses.
What are the Treatment Options for Hepatitis Virus?
Hepatitis treatment depends on the type of hepatitis virus involved, the stage of the infection, and the patient’s general health. While some types of hepatitis resolve on their own, others require medical intervention to prevent serious liver damage. Here are some common treatment types and symptom management options for different types of hepatitis virus:
Treatment for Acute Hepatitis A and E
Acute hepatitis A and E infections are usually self-limiting, meaning they resolve on their own without causing long-term liver damage. Treatment mainly focuses on supportive care, which includes plenty of rest, proper nutrition, and staying well-hydrated. Most people recover fully within a few weeks to months without any specific antiviral medication.
Treatment for Chronic Hepatitis B
Chronic hepatitis B often requires antiviral medications to suppress the virus and prevent liver damage. Commonly prescribed drugs include tenofovir and entecavir, which help reduce the amount of virus in the body. Treatment may be long-term, sometimes lifelong, depending on the severity of the infection and the patient's response. Regular monitoring of liver function and viral load is essential to manage the disease effectively. In advanced cases with significant liver damage, a liver transplant may be necessary.
Treatment for Chronic Hepatitis C
Chronic hepatitis C is now highly curable with direct-acting antiviral (DAA) medications. These oral treatments typically last 8 to 12 weeks and have a high success rate, often clearing the virus completely with minimal side effects. Early diagnosis and treatment significantly reduce the risk of complications such as liver cirrhosis and liver cancer.
Treatment for Hepatitis D
Treatment for hepatitis D is more complicated because this virus requires hepatitis B to replicate. Managing hepatitis D generally involves treating the underlying hepatitis B infection. Some patients may benefit from interferon-based therapies, but the effectiveness varies. Research is ongoing to find more targeted and effective treatments for hepatitis D.
Management of Hepatitis-Related Liver Damage
For patients with advanced liver disease caused by hepatitis, ongoing management is crucial to monitor and prevent complications like cirrhosis or liver cancer. Lifestyle changes such as avoiding alcohol, eating a healthy diet, and maintaining a healthy weight can support liver health. In severe cases, liver transplantation may be the only option. Regular medical follow-ups are essential to track disease progression and adjust treatment as needed.
What are the Prevention Tips for Hepatitis Virus?
Hepatitis prevention is crucial to reducing the global burden of liver disease. While some types of hepatitis can be prevented with vaccines, others require changes in behaviour and public health measures. By understanding how each type is transmitted, we can take effective steps to protect ourselves and others.
Vaccination
Hepatitis A and B can be effectively prevented through vaccination. The hepatitis B vaccine also indirectly protects against hepatitis D, which only occurs in those already infected with hepatitis B.
These vaccines are safe, widely available, and recommended for all infants, healthcare workers, and high-risk individuals.
In some regions, a hepatitis E vaccine is available, mainly for use in outbreak situations, although it is not yet globally accessible.
Safe Food and Water Practices
Hepatitis A and E are transmitted through the faecal-oral route, usually from contaminated food or water.
To prevent infection, drink only clean, safe water, eat properly cooked food, and practice good hand hygiene, especially in areas with poor sanitation.
Avoid raw or undercooked shellfish and food from questionable sources while traveling.
Safe Sex Practices
Hepatitis B and, less commonly, hepatitis C can be spread through unprotected sex.
Using condoms and being aware of your partner’s health status can significantly reduce the risk.
Individuals with multiple sexual partners or those with STIs should be regularly tested.
Avoid Sharing Personal Items
Never share razors, toothbrushes, or nail clippers, as they can carry traces of infected blood.
People who inject drugs should use new, sterile needles every time and avoid sharing injection equipment.
Safe Medical and Cosmetic Procedures
Always ensure sterile equipment is used during medical procedures, blood transfusions, dental care, tattoos, or piercings.
Only visit licensed and reputable providers who follow strict hygiene and sterilization standards.
Blood Screening and Organ Donation
In healthcare settings, proper blood screening before transfusions and ensuring safe organ transplants help prevent the spread of hepatitis B and C.
This is especially important in regions where access to reliable screening is limited.
Maternal Screening and Infant Vaccination
Pregnant women should be screened for hepatitis B. If positive, appropriate steps, including immediate vaccination of the newborn, can prevent transmission from mother to child.
Newborns should receive the hepatitis B vaccine within 24 hours of birth as part of routine immunisation.
