Hepatitis Awareness: Types, Prevention & Government Initiatives
When is World Hepatitis Day and What is This Year’s Theme?
On July 28, the world commemorates World Hepatitis Day. The purpose of World Hepatitis Day is to support hepatitis prevention, diagnosis, and treatment. In 2023, the theme of World Hepatitis Day is set to be "One Life, One Liver."
Hepatitis: Introduction
The term "hepatitis" refers to a group of infectious diseases that primarily affect the liver. It is derived from the Greek words "hepar" (which means liver) and "-itis" (which denotes inflammation). It has been acknowledged for centuries and there is historical proof from early civilisations. But in recent years, our knowledge of hepatitis has significantly changed.During a hepatitis infection, the liver, a crucial organ in charge of detoxification, metabolism, and nutrient storage, turns into a battlefield. In this blog, we will discuss the followings - What are the different types of hepatitis, hepatitis and liver cancer, hepatitis prevention strategies, and government initiatives to fight hepatitis.
The Different Types of Hepatitis:
Liver disease can be brought on by a variety of things, including viruses, alcohol, toxins, and autoimmune reactions. But in this blog, we will focus on understanding types of viral hepatitis that is A, B, C, D, and E.1. Hepatitis A: The Contagious Liver Infection – Hepatitis A is typically spread via the fecal-oral route, which is frequently caused by improper sanitation and hygiene practises. The virus can spread more easily through contaminated food, water, or close contact with an infected person. Hepatitis A rarely results in permanent liver damage, despite the fact that it can be uncomfortable and cause symptoms like fatigue and jaundice.
Most people get completely better in a few weeks or months. Hepatitis A vaccines have been developed, especially for those who are more likely to contract the disease, such as tourists who visit unsanitary areas or people who work in certain occupations.
2. Hepatitis B: The Silent Threat – Hepatitis B is a serious health risk for people all over the world since the infection can spread through sexual contact, infected blood, and from mother to child during childbirth. Being known as a "silent" infection stems from the fact that many people with chronic hepatitis B initially exhibit no symptoms.
However, it can eventually worsen and lead to serious liver problems like cirrhosis and liver cancer. Hepatitis B vaccination is advised for everyone, but it's especially important for infants and high-risk groups like nurses and people who have multiple sexual partners.
3. Hepatitis C: The Chronic Liver Disease – Blood-to-blood contact is the main way that the Hepatitis C virus spreads. It may cause chronic infection and, if left untreated, cirrhosis, hepatocellular carcinoma, and progressive liver damage.
There is no vaccine for Hepatitis C, in contrast to Hepatitis A and B. However, developments in medical science have resulted in the creation of direct-acting antiviral drugs, which have high cure rates and improve the prognosis for people with hepatitis C.
4. Hepatitis D: The Coinfection Factor – Hepatitis D, also referred to as "delta hepatitis," can only affect people who have already contracted hepatitis B. More severe liver disease is frequently caused by this coinfection than by Hepatitis B alone.
Similar to Hepatitis B, Hepatitis D is primarily spread through blood and sexual contact. Hepatitis B infection can be prevented through vaccination, which also lowers the chance of developing Hepatitis D.
5. Hepatitis E: The Waterborne Menace – Contaminated water is a major source of hepatitis E transmission, especially where facilities for sanitation are lacking. Hepatitis E infection during pregnancy increases the risk of fatal complications such as fulminant hepatitis.
Hepatitis E typically disappears without the need for treatment. Pregnant women and those with weakened immune systems, however, require close observation and medical care.
Hepatitis and Liver Cancer:
Hepatocellular carcinoma, or HCC, is a type of liver cancer that can develop when a person has a chronic infection with certain hepatitis viruses, particularly Hepatitis B and C. These viruses can cause the liver to become chronically inflammatory, which can result in liver nodules that eventually turn into cancerous tumours.1. Hepatitis B and Liver Cancer – One of the main risk factors for liver cancer is chronic hepatitis B infection. HCC is more likely to develop when there is an extended blood concentration of the Hepatitis B surface antigen (HBsAg) and elevated liver enzyme levels. The risk of liver cancer in people with chronic hepatitis B can be decreased, though, by early detection and antiviral therapy.
2. Hepatitis C and Liver Cancer – Another important risk factor for liver cancer is persistent Hepatitis C infection. A person is more likely to develop HCC the longer they have had HCV infection and the higher their viral load. People with chronic hepatitis C may experience a lower risk of developing liver cancer if they receive effective treatment with direct-acting antivirals (DAAs).
3. Fibrosis and Cirrhosis – The risk of liver cancer is significantly increased when chronic hepatitis infections result in the development of liver fibrosis (liver scarring) and cirrhosis (advanced liver scarring). People with cirrhosis need to be regularly monitored and under surveillance in order to detect HCC early because it is regarded as a precancerous condition.
Hepatitis Prevention Strategies:
Hepatitis infections need to be prevented and controlled using a multifaceted strategy that includes vaccination, screening, safe practises, education, and collaboration. The prevalence of hepatitis and the complications it causes are being reduced as a result of public health initiatives aimed at at-risk groups and vulnerable communities. The elimination of viral hepatitis as a significant threat to public health requires an extensive and coordinated effort at the global, regional, and local levels.1. Vaccination: Particularly for Hepatitis A and B, vaccination is a crucial component of hepatitis prevention. Hepatitis A and B vaccines can be obtained easily, safely, and effectively. The prevalence of these infections is significantly lowered by immunising at-risk individuals, healthcare professionals, and visitors to areas with a high hepatitis prevalence.
2. Screening and Testing: Regular hepatitis testing and screening are essential for early diagnosis and effective treatment, especially in high-risk populations. Through screening, it is possible to find asymptomatic carriers and take the necessary preventive and medical measures.
3. Safe Injection Practices: In order to stop the spread of hepatitis, especially Hepatitis C, it is essential to promote safe injection techniques, especially among intravenous drug users and in medical settings. Infection risk can be decreased with the use of sterile, clean needles and appropriate infection control procedures.
4. Blood and Organ Donation Screening: In order to stop the spread of hepatitis through blood transfusions and organ transplants, strict screening procedures for blood and organ donations are necessary. The recipients' health is protected by making sure that all donated blood and organs are thoroughly tested for hepatitis viruses.
5. Education and Awareness Campaigns: In order to stop hepatitis infections, public health programmes emphasising education and awareness are essential. Through these campaigns, the public is meant to be made aware of the various types of hepatitis and their transmission methods, risk factors, and treatment options.
6. Improving Sanitation and Water Quality: Improving sanitation and water quality is crucial for reducing the risk of waterborne transmission in areas where Hepatitis E is prevalent. Hepatitis E is made less prevalent by proper sewage management, safe drinking water accessibility, and hygiene instruction.
7. Treatment and Care Access: It is critical to guarantee that people with chronic hepatitis have access to appropriate medical care and treatment. Direct-acting antivirals (DAAs) for Hepatitis C and antiviral medications for Hepatitis B have revolutionised treatment outcomes, resulting in viral suppression and better patient quality of life.
8. Public Health Surveillance: In order to track the prevalence, incidence, and trends of hepatitis infections, effective public health surveillance systems are crucial. The early detection and response to outbreaks are made possible by surveillance data, which also helps inform targeted prevention efforts.
9. Global and Regional Collaboration: In order to reduce the burden of hepatitis on the world, cooperation between nations and regions is essential. A unified approach to prevention, treatment, and control is fostered by the sharing of best practises, resources, and knowledge.
Indian Government Initiatives to Fight Hepatitis:
To combat hepatitis and minimize its impact on public health, the Indian government has put in place a number of initiatives and programmes. Here are a few of these crucial initiatives taken to combat hepatitis by Indian government:1. National Viral Hepatitis Control Program (NVHCP): The NVHCP, which was introduced in 2018, aims to prevent and control viral hepatitis, especially Hepatitis B and C. The programme focuses on increasing awareness, offering free hepatitis testing and treatment, and strengthening the healthcare system for efficient management.
2. Universal Immunization Program (UIP): As part of their regular immunisation schedule, the UIP offers free Hepatitis B vaccination to all infants. In accordance with the regulations, children are given different doses of vaccine as they reach specific ages.
3. Pradhan Mantri Jan Arogya Yojana (PMJAY): The government offers families who are economically vulnerable health insurance coverage through this programme, also known as Ayushman Bharat. The PMJAY ensures that access to healthcare does not become restricted by financial limitations by providing coverage for the treatment of hepatitis and other illnesses.
4. National Health Mission (NHM): The NHM includes numerous health initiatives, such as hepatitis prevention and management. It focuses on enhancing healthcare delivery systems, developing capacity, and raising hepatitis awareness among the general public.
5. Integrated Counselling and Testing Centres (ICTCs): These facilities provide private HIV, Hepatitis B, and Hepatitis C testing and counselling services. Early detection, counselling, and referral for suitable care and treatment are all crucial tasks performed by ICTCs.
6. National AIDS Control Organization (NACO): NACO supports the prevention and treatment of viral hepatitis despite being primarily HIV/AIDS-focused. It attempts to reduce the spread of hepatitis via shared injection equipment and blood transfusions.
Together, these initiatives and programmes aim to improve hepatitis early detection and treatment, lower the prevalence of the disease, and raise public awareness of it. To succeed in the goal of eradicating hepatitis as a significant public health issue in India, however, ongoing efforts, awareness, and resources are necessary.
