Why in News?
The recently released Global Hepatitis Report 2024 by the World Health Organisation (WHO) has highlighted India as one of the nations facing a significant burden of viral hepatitis, particularly Hepatitis B and C infections.
What are the Key Findings of the Report?
- India's Hepatitis Burden:
- Prevalence in India:
- India is one of the countries with the highest burden of viral hepatitis.
- India has an estimated 2.9 crore people living with Hepatitis B infection and 0.55 crore living with Hepatitis C infection.
- There were over 50,000 new Hepatitis B cases and 1.4 lakh new Hepatitis C cases reported in India in 2022.
- These viral hepatitis infections killed 1.23 lakh people in India in 2022.
- Drivers of Hepatitis Infections in India:
- Both Hepatitis B and C infections are transmitted through various means, including mother-to-child transmission, unsafe blood transfusions, contact with infected blood, and needle-sharing among drug users.
- Despite advancements in blood safety protocols, mother-to-child transmission remains a primary mode of infection for Hepatitis B in India.
- Both Hepatitis B and C infections are transmitted through various means, including mother-to-child transmission, unsafe blood transfusions, contact with infected blood, and needle-sharing among drug users.
- Diagnosis and Treatment Coverage:
- In India, only 2.4% of Hepatitis B cases and 28% of Hepatitis C cases are diagnosed.
- Treatment coverage is even lower, at 0% for Hepatitis B and 21% for Hepatitis C, despite the availability of affordable generic medicines.
- Barriers to Improving Hepatitis Outcomes:
- Limited reach and utilisation of the National Viral Hepatitis Control Program.
- Need to expand access to affordable diagnostics and treatment services under the program.
- Requirement to treat all diagnosed individuals, regardless of disease stage, to reduce health consequences and transmission.
- Prevalence in India:
- Global:
- Mortality Trends:
- Viral hepatitis caused an estimated 1.3 million deaths globally in 2022, on par with tuberculosis.
- Hepatitis B accounted for 83% of these deaths, while hepatitis C accounted for 17%.
- The rise in mortality suggests an increase in hepatitis-related liver cancer cases and deaths.
- The number of new viral hepatitis infections declined from 2.5 million in 2019 to 2.2 million in 2022.
- Viral hepatitis caused an estimated 1.3 million deaths globally in 2022, on par with tuberculosis.
- Prevalence:
- Globally, an estimated 304 million people were living with hepatitis B and C in 2022.
- WHO estimates indicate that 254 million people lived with hepatitis B and 50 million with hepatitis C in 2022.
- 12% of the burden is among children, particularly for hepatitis B.
- Globally, an estimated 304 million people were living with hepatitis B and C in 2022.
- Barriers to Scaling Up Testing and Treatment:
- Lack of funding and limited decentralisation have restricted the scaling up of testing services.
- Many countries are still not procuring hepatitis medicines at the available generic prices, leading to high costs.
- Patent-related barriers remain an obstacle to accessing affordable hepatitis C medicines in some countries.
- Mortality Trends:
What are the Key Facts About Hepatitis?
- About:
- Hepatitis is caused by infectious viruses (viral hepatitis), and noninfectious agents, leading to a range of health problems, some of which can be fatal.
- There are five main strains of the hepatitis virus: A, B, C, D, and E, each with different modes of transmission, severity, geographical distribution, and prevention methods.
- Types B and C are the most common cause of liver cirrhosis (a condition in which the liver is scarred and permanently damaged), liver cancer, and viral hepatitis-related deaths.
- Some types of hepatitis are preventable through vaccination, and an estimated 4.5 million premature deaths could be prevented by 2030 through vaccination, diagnostic tests, medicines, and education campaigns.
- WHO's global hepatitis strategy aims to reduce new hepatitis infections by 90% and deaths by 65% between 2016 and 2030.
- Symptoms and Severity:
- Hepatitis A, B, C, D, and E can exhibit mild or no symptoms.
- Symptoms of hepatitis A, B, and C include fever, malaise, loss of appetite, diarrhoea, nausea, abdominal discomfort, dark-coloured urine, and jaundice.
- Chronic liver infection, cirrhosis, and liver cancer can result from hepatitis A, B, and C.
- Hepatitis D is found in people already infected with hepatitis B and can cause a more serious infection and accelerated progression to cirrhosis. Chronic hepatitis D is rare.
- Hepatitis E symptoms include mild fever, reduced appetite, nausea, vomiting, abdominal pain, itching, skin rash, joint pain, jaundice, dark urine, pale stools, and hepatomegaly or acute liver failure.
Way Forward
- Treating an estimated 40 million people with hepatitis B and curing 30 million people with hepatitis C by 2026 is crucial to regain the trajectory towards elimination.
- Targeted efforts are required to reach specific high-risk populations affected by viral hepatitis.
- Integrate hepatitis services into primary healthcare settings to improve access for individuals across all socioeconomic backgrounds.
- Expand and improve the National Viral Hepatitis Control Program by increasing funding, broadening its scope, and enhancing coordination among stakeholders. Prioritise early diagnosis and treatment initiation through the program.
