KEY POINTS
- Hepatitis:
-
- Hepatitis refers to an inflammatory condition of the liver.

HEPATITIS IN INDIA
- 40 million people are chronically infected with the Hepatitis B virus and 6 to 12 million with the Hepatitis C virus.
- In 2018 the National Viral Hepatitis Control Programme (NVHCP) was launched which has the target to eliminate Hepatitis C by 2030. The program is the largest program for Hepatitis B and C diagnosis and treatment in the world.
- Hepatitis B is included under India’s Universal Immunization Programme (UIP) which provides free of cost vaccination against a total of 12 vaccine-preventable diseases.
- The first recombinant DNA-based vaccine for Hepatitis B infection was made in India by Hyderabad-based Shantha Biotech.
