World Hepatitis Day , 28th July : Raising Awareness and Promoting Global Hepatitis Elimination

World Hepatitis Day , 28th July : Raising Awareness and Promoting Global Hepatitis Elimination

World Hepatitis Day, observed annually on July 28, is one of eight official global public health campaigns marked by the World Health Organization (WHO). The day aims to raise awareness of viral hepatitis, a group of infectious diseases known as hepatitis A, B, C, D, and E, and encourage prevention, diagnosis, and treatment. The significance of this day is underscored by the global burden of hepatitis, which affects millions of people worldwide and leads to severe health conditions such as liver cirrhosis and liver cancer.

History and Significance

Origin and Establishment

The first World Hepatitis Day was established in 2008 by the World Hepatitis Alliance, a patient-led and patient-driven non-governmental organization. Initially celebrated on May 19, the date was later changed to July 28 in 2010 to honor the birthday of Dr. Baruch Blumberg, the Nobel Laureate who discovered the hepatitis B virus and developed the first hepatitis B vaccine. This change was also part of the WHO's efforts to bring more global attention to the disease.

Objectives

World Hepatitis Day aims to achieve the following objectives:

1. Raise Awareness: Educate the public about the various types of hepatitis and the risks associated with the disease.
2. Promote Prevention: Highlight the importance of preventive measures such as vaccination, safe blood transfusions, and hygienic practices.
3. Encourage Testing and Diagnosis: Motivate individuals to get tested, especially those at higher risk, to ensure early diagnosis and treatment.
4. Support Treatment and Care: Advocate for access to treatment and care services for those affected by hepatitis.
5. Eliminate Stigma: Combat the stigma and discrimination associated with hepatitis to support affected individuals and communities.

Types of Hepatitis

Hepatitis A

Hepatitis A is a highly contagious liver infection caused by the hepatitis A virus (HAV). It is typically spread through ingestion of contaminated food and water or direct contact with an infectious person. While hepatitis A does not cause chronic liver disease, it can cause debilitating symptoms and, in rare cases, fulminant hepatitis (acute liver failure), which can be fatal.

• Symptoms: Fever, fatigue, loss of appetite, nausea, vomiting, abdominal pain, dark urine, and jaundice.
• Prevention: Effective vaccines are available, and improved sanitation and food safety measures can prevent transmission.

Hepatitis B

Hepatitis B is a serious liver infection caused by the hepatitis B virus (HBV). It can be transmitted through contact with infectious body fluids, such as blood, semen, and vaginal fluids. Hepatitis B can cause both acute and chronic infections, leading to liver cirrhosis and liver cancer if untreated.

• Symptoms: Jaundice, fatigue, abdominal pain, loss of appetite, nausea, and joint pain.
• Prevention: A safe and effective vaccine is available. Preventive measures include safe injection practices, screening blood donations, and safe sex practices.

Hepatitis C

Hepatitis C is a liver infection caused by the hepatitis C virus (HCV). It is primarily spread through blood-to-blood contact. While many people with hepatitis C do not exhibit symptoms, chronic infection can lead to severe liver damage, cirrhosis, and liver cancer.

• Symptoms: Fatigue, jaundice, dark urine, abdominal pain, and joint pain.
• Prevention: There is no vaccine for hepatitis C. Prevention relies on safe injection practices, screening blood donations, and avoiding sharing needles or other drug paraphernalia.

Hepatitis D

Hepatitis D, also known as delta hepatitis, is caused by the hepatitis D virus (HDV). It is a defective virus that requires the presence of hepatitis B virus to replicate. Hepatitis D infection can only occur in individuals who are already infected with hepatitis B, either as a co-infection or superinfection.

• Symptoms: Similar to hepatitis B but often more severe.
• Prevention: Vaccination against hepatitis B prevents hepatitis D infection. Management includes antiviral therapy for hepatitis B.

Hepatitis E

Hepatitis E is a liver disease caused by the hepatitis E virus (HEV). It is primarily transmitted through ingestion of contaminated water. Hepatitis E is usually self-limiting, but it can be severe in pregnant women and individuals with weakened immune systems.

• Symptoms: Fever, fatigue, loss of appetite, nausea, vomiting, abdominal pain, jaundice, and dark urine.
• Prevention: Improving sanitation, safe drinking water, and good personal hygiene practices are crucial for prevention. A vaccine is available in China but not widely accessible globally.

Global Burden of Hepatitis

Epidemiology

Viral hepatitis affects millions of people worldwide, causing significant morbidity and mortality. According to WHO estimates, approximately 325 million people live with chronic hepatitis B and C, and about 1.34 million people die annually due to hepatitis-related liver disease.

• Hepatitis A: Predominantly affects regions with poor sanitation, including parts of Africa, Asia, and Latin America.
• Hepatitis B: Highly endemic in sub-Saharan Africa, East Asia, and parts of the Pacific Islands.
• Hepatitis C: Prevalent in regions with high rates of unsafe medical practices, such as Egypt, Central Asia, and Eastern Europe.
• Hepatitis D: Coexists with hepatitis B, with higher prevalence in the Mediterranean Basin, Middle East, and parts of South America.
• Hepatitis E: Common in regions with inadequate water supply and sanitation, such as South Asia, Africa, and Central America.

Economic Impact

The economic burden of hepatitis is substantial, encompassing direct medical costs, productivity losses, and long-term disability. The costs of treatment and management, especially for chronic hepatitis B and C, can be significant, straining healthcare systems and individuals' finances.

Strategies for Prevention and Control

Vaccination

Vaccination is a cornerstone of hepatitis prevention. Safe and effective vaccines are available for hepatitis A and B, which also indirectly prevent hepatitis D.

• Hepatitis A Vaccine: Recommended for children in high-risk areas, travelers to endemic regions, and individuals with chronic liver disease.
• Hepatitis B Vaccine: Included in routine childhood immunization programs in many countries and recommended for high-risk groups such as healthcare workers and people with multiple sexual partners.

Safe Practices

• Blood Safety: Ensuring blood transfusions and organ transplants are screened for hepatitis viruses.
• Injection Safety: Promoting the use of sterile needles and syringes in healthcare and community settings.
• Safe Sex Practices: Using condoms and reducing the number of sexual partners to prevent sexually transmitted hepatitis B and C.

Public Awareness and Education

Raising awareness through educational campaigns helps reduce the stigma associated with hepatitis and promotes preventive behaviors. Public health messages should emphasize the importance of vaccination, safe practices, and regular testing.

Screening and Diagnosis

Early detection through screening programs is essential for managing hepatitis and preventing complications. High-risk groups, including people who inject drugs, healthcare workers, and individuals with multiple sexual partners, should be prioritized for testing.

Treatment and Care

Access to antiviral therapies for hepatitis B and C has improved significantly, but challenges remain in ensuring equitable access. Treatment can reduce the viral load, prevent liver damage, and improve quality of life for those affected.

Policy and Advocacy

Strong political commitment and effective policies are crucial for combating hepatitis. Governments should integrate hepatitis prevention and control into national health strategies, allocate sufficient resources, and engage stakeholders, including affected communities, healthcare providers, and international organizations.
