World Hepatitis Day serves as a powerful reminder that viral hepatitis remains one of the world’s most serious yet often overlooked public health challenges. Across the World Health Organization’s Western Pacific Region, more than 100 million people are living with hepatitis B or hepatitis C, representing more than one-third of the global disease burden. Despite the availability of effective prevention, testing, and treatment, millions remain unaware of their infection or are unable to access the healthcare services they need.

The Western Pacific Region includes a diverse group of countries and territories stretching across East Asia, Southeast Asia, and the Pacific. While healthcare systems have made significant progress in recent decades, hepatitis continues to place a heavy burden on individuals, families, and national health services. The disease often progresses silently, with many people experiencing no symptoms for years until severe liver damage has already occurred.

Hepatitis B and hepatitis C are viral infections that primarily attack the liver. Both viruses can cause chronic infection, leading to progressive inflammation and permanent liver damage over time. If left untreated, chronic hepatitis may develop into liver cirrhosis, liver failure, or hepatocellular carcinoma, the most common form of primary liver cancer. Together, these complications contribute to hundreds of thousands of preventable deaths every year worldwide.

One of the greatest challenges in combating hepatitis is that many infected individuals remain undiagnosed. Because the disease frequently causes few or no early symptoms, people may unknowingly carry the virus for decades while continuing to transmit it to others. Without routine screening, infections often remain hidden until advanced liver disease develops, reducing treatment options and increasing healthcare costs.

Expanding access to hepatitis testing has therefore become a central public health priority. Simple blood tests can identify hepatitis B and C infections, allowing healthcare providers to begin appropriate monitoring or treatment before irreversible liver damage occurs. Early diagnosis also enables patients to adopt healthier lifestyles, receive vaccinations where appropriate, and reduce the risk of transmitting the virus to family members or others.

Medical advances have transformed the outlook for people living with viral hepatitis. Although chronic hepatitis B cannot yet be completely cured, antiviral medications can effectively suppress the virus, reduce liver inflammation, and significantly lower the risk of cirrhosis and liver cancer. Hepatitis C has become one of the few chronic viral diseases that can be cured in most patients through modern direct-acting antiviral medicines, often within a few months of treatment.

Vaccination remains one of the most successful tools for preventing hepatitis B. Routine immunisation of newborns and children has dramatically reduced infection rates in many countries and is considered one of the most effective public health interventions for preventing liver disease later in life. Combined with safe medical practices, infection-control measures, blood screening, and public awareness campaigns, vaccination continues to play a vital role in reducing transmission.

Despite these advances, barriers to healthcare persist across many communities. Limited awareness, social stigma, financial constraints, inadequate healthcare infrastructure, and unequal access to diagnostic services often prevent people from seeking testing or continuing treatment. In rural and underserved regions, shortages of trained healthcare professionals and laboratory facilities further complicate efforts to identify and manage infections.

Public education campaigns linked to World Hepatitis Day aim to address these challenges by encouraging people to learn about hepatitis, understand their personal risk, and seek medical advice when appropriate. Increasing awareness helps dispel misconceptions surrounding the disease while promoting earlier diagnosis and reducing discrimination against people living with chronic viral infections.

Healthcare experts also emphasise the importance of integrating hepatitis services into broader primary healthcare systems. Combining screening with routine health check-ups, maternal healthcare, HIV programmes, and community outreach initiatives can improve early detection while making services more accessible and affordable.

The fight against hepatitis aligns closely with the World Health Organization’s goal of eliminating viral hepatitis as a public health threat by 2030. Achieving this objective will require sustained investment in vaccination programmes, affordable diagnostics, treatment access, healthcare workforce training, surveillance systems, and public awareness initiatives. Governments, healthcare providers, international organisations, and civil society all have essential roles in expanding access to life-saving services.

For individuals, one of the most effective actions is simply getting tested. Knowing one’s hepatitis status allows people to receive timely care, protect family members, and prevent long-term complications. Early treatment not only improves health outcomes but also reduces future healthcare costs associated with advanced liver disease.

As World Hepatitis Day draws global attention to this preventable and treatable disease, the message remains clear: breaking down barriers to testing, treatment, and prevention can save millions of lives. Through stronger healthcare systems, expanded public awareness, and equitable access to medical services, countries across the Western Pacific and beyond have an opportunity to significantly reduce the burden of hepatitis and move closer to a future free from this silent but deadly disease.
