Quantifying Hepatitis B and C Burden in Asia

CDA Foundation, Asia

Viral hepatitis continues to be one of the deadliest infections in the world, attributed as the cause of one death every 25 seconds, as well as being identified as the leading cause of liver cancer in the world.  Most cases of hepatitis B virus (HBV) and hepatitis C virus (HCV) infections are in Asia, so it is important to quantify the disease burden in Asia to help international agencies, public health organizations and policy-makers develop strategies to eliminate these infections.

Today, there are many treatments to eliminate viral hepatitis.  With the availability of vaccines that can effectively prevent Hepatitis B, many countries have adopted large-scale vaccination practices for infants, one such example being China. Treatment for Hepatitis B has also been developed for patients who had been infected prior to the availability of vaccines, and existing treatments for Hepatitis C can cure patients within the span of 12 weeks.  However, many cases of HBV and HCV still remain untreated to this day.

Since 2018, the ZeShan Foundation has been providing funding to the Center for Disease Analysis Foundation in their efforts to help countries in Asia eliminate hepatitis B and C in the region.  To study and publish a report on the breadth of hepatitis B and C burden across Asia, the CDA Foundation worked closely with Asian countries to collect data on the number of people infected, diagnosed, and treated. In this project, mathematical models were used to estimate the impact of viral hepatitis in Asia, the summary of which is shown below.  From the data collected, an estimate of 188 million people in Asia are infected with hepatitis B (Figure 1) and another 34 million with hepatitis C (Figure 2).  For more details, please view the CDA Foundation’s website:  https://cdafound.org/dashboard/polaris/dashboard.html.

The compiled research reveals that a majority of global HBV- and HCV-related cases of liver cancer and liver related deaths are concentrated in Asia (Figure 3).  This analysis will help Asian countries obtain more funding for the elimination of viral hepatitis, and additionally recruit support from their government to test and treat this population through HBV vaccinations.

When an unknown printer took a galley of type and scrambled it to make a type specimen book.

Neque porro quisquam est qui dolorem ipsum quia dolor sit amet, consectetur, adipisci velit…Lorem Ipsum is simply dummy text of the printing and typesetting industry. Lorem Ipsum has been the industry’s standard dummy text ever since the 1500s, when an unknown printer took a galley of type and scrambled it to make a type specimen book. It has survived not only five centuries, but also the leap into electronic typesetting, remaining essentially unchanged. It was popularised in the 1960s with the release of Letraset sheets containing Lorem Ipsum passages, and more recently with desktop publishing software like Aldus PageMaker including versions of Lorem Ipsum.

When an unknown printer took a galley of type and scrambled it to make a type specimen book. It is a long established fact that a reader will be distracted by the readable content of a page when looking at its layout. The point of using Lorem Ipsum is that it has a more-or-less normal distribution of letters, as opposed to using ‘Content here, content here’, making it look like readable English. Many desktop publishing packages and web page editors now use Lorem Ipsum as their default model text, and a search for ‘lorem ipsum’ will uncover many web sites still in their infancy. Various versions have evolved over the years, sometimes by accident, sometimes on purpose (injected humour and the like).

Combating Hepatitis in Western Pacific Region

World Health Organisation Office for the Western Pacific Region (WPRO), Asia

Since 2013, ZeShan Foundation has been providing support to the World Health Organisation Office for the Western Pacific Region (WPRO). ZeShan’s grants aid WPRO in combating viral hepatitis in the region, and includes the allocation of specific support to the China office.

Viral hepatitis is responsible for 1.4 million deaths globally. There are estimated to be 115 million people with chronic hepatitis B (HBV) infection and 14 million with chronic hepatitis C (HCV) infection living in the Western Pacific Region, accounting for 40 % of people burdened with chronic hepatitis B and C across the globe. 

Chronic HBV and HCV is known to lead to the development of cirrhosis and liver cancer over time. With 60% of the worlds’ affected population, the Western Pacific Region has the highest number of deaths caused by liver cancer globally, which is also the 6th top cause of death in the region. Six of the top ten countries with the highest incidence (new annual cases) of liver cancer in the world include Mongolia (highest incidence globally), Viet Nam, Lao People’s Democratic Republic, Cambodia, China and South Korea.  This being said, early testing and treatment can effectively reduce the progression of these diseases and subsequently the risk of development of liver cancer.

The grant support from ZeShan Foundation has vaulted WPRO into leading the action on viral hepatitis in the Region, and has allowed the organization to establish regional responses in the effort to eliminate viral hepatitis as outlined by the Global Health Sector Strategy for Viral Hepatitis 2016-2021 . With the elimination of viral hepatitis being highlighted within the 2030 Sustainable Development Goals, the Regional Action Plan for Viral Hepatitis in the Western Pacific 2016-2020  has been endorsed by all countries in the Western Pacific Region, which defines specific actions to be taken in order to better understand hepatitis epidemics. The outlined actions include awareness and knowledge building among stakeholders, strengthening public policy, and data generation, which will also be essential factor in the process of enhancing prevention strategies and improving access to affordable screening, diagnosis and treatment of hepatitis B and C.

Figure 1 illustrates the current progress in hepatitis response programmes in the Western Pacific Region, which underscores the critical importance of national leadership, development of national response plans and having data to inform policy and decision making.

Supporting countries to scale up interventions towards hepatitis elimination

The Western Pacific Region has led global efforts in working towards hepatitis elimination. Some of the regional successes include the triple elimination of mother-to-child transmission of HIV, syphilis, and hepatitis B, as well as the scaled up hepatitis testing and treatment encompassed in Universal Health Coverage.

Raising public awareness on viral hepatitis

To improve awareness around viral hepatitis and its impact on health, WHO offices in all countries work closely with the Ministries of Health and their partners to provide information to the public. Every year, awareness is raised globally through World Hepatitis Day on 28th July.
