The Persistent Public Health Challenge of Hepatitis in India
Despite advancements in vaccination, sanitation, and public health initiatives since the 1950s, hepatitis remains a significant cause of mortality in India. The core challenges persist: silent transmission, low public awareness, and delayed medical intervention.
Viral Classification and Impact
Hepatitis is a group of five distinct viruses that affect the liver:
-
Hepatitis A and E: Transmitted via the fecal-oral route through contaminated food and water. They typically cause acute, short-term infections and are prevalent in areas with poor sanitation. Hepatitis E poses a significant risk to pregnant women.
-
Hepatitis B and C: Transmitted through infected blood and bodily fluids. These can lead to chronic, long-term infections, potentially progressing to cirrhosis and liver cancer if not managed.
-
Hepatitis D: A secondary infection that only affects individuals already infected with Hepatitis B.
National Prevalence vs. Actual Burden
According to the 2023 HIV Sentinel Surveillance Plus report, India is classified as a "low prevalence" country by WHO standards, with national seroprevalence rates of approximately for Hepatitis B and or Hepatitis C. However, these percentages translate to millions of infected individuals, a majority of whom are unaware of their condition. Diagnosis often occurs only after the onset of severe complications, such as liver damage or cancer.
Key Factors Driving Hepatitis Transmission
Several factors contribute to the ongoing prevalence of hepatitis in India:
-
Seasonal Spikes: The monsoon season consistently triggers a sharp increase in acute viral hepatitis A and E cases, with some hospitals recently reporting a 40% rise. This is attributed to waterlogging and contamination of water sources.
-
Delayed Diagnosis: Subtle initial symptoms, such as fatigue and mild jaundice, are often dismissed. A common misconception that jaundice is self-limiting leads to critical delays in seeking medical care, which can result in acute liver failure requiring transplantation.
-
Systemic Deficiencies:
-
Screening and Awareness: Routine screening is uncommon, particularly in rural and semi-urban regions. Public understanding of the different hepatitis types, their transmission, and symptoms is critically low.
-
Healthcare Infrastructure: A lack of trained personnel for early detection, coupled with the high cost of treatment and patchy vaccine coverage, presents significant barriers to effective control.
-
Unsafe Practices: Transmission of Hepatitis B and C is fueled by unsafe medical practices, including unsterilized equipment in informal clinics and inadequately screened blood transfusions. For Hepatitis A and E, a lack of access to safe drinking water and basic sanitation remains a fundamental problem, as seen in recurrent outbreaks in states like Kerala.

Recommendations for Control and Prevention
Experts recommend a multi-pronged strategy focused on shifting from treatment to prevention:
-
Vaccination: Integrate the Hepatitis B vaccine universally into birth and school immunization schedules.
-
Screening: Launch targeted, mass screening campaigns for high-risk groups, including pregnant women and healthcare workers.
-
Infection Control: Enforce strict safety and sterilization protocols across all healthcare facilities, from large hospitals to local clinics.
-
Treatment Accessibility: Subsidize and improve access to treatments, especially for Hepatitis C.
-
Public Education: Utilize community health workers and local institutions to raise awareness about hygiene, symptoms, and prevention.
-
Capacity Building: Train primary healthcare workers to recognize early signs of hepatitis and facilitate timely referrals.
