Hepatitis B-Part 2: Treatment and Prevention

Hepatitis B is a potentially life-threatening liver infection caused by the hepatitis B virus (HBV). It can cause chronic infection and puts people at high risk of death from cirrhosis and liver cancer.

In the first part of the article, you have read the epidemiology, mode of transmission of Hepatitis B virus, its sign and symptoms, groups at risk, the relationship of HBV and HIV infection, and how the diagnosis is confirmed. In this part of the article, we shall discuss about its treatment and prevention.

You can also take a free mock test on Hepatitis B.

Hepatitis B: Part 1 - Epidemiology and Clinical Features

Overview 

Hepatitis is an inflammation of the liver that's caused by a variety of contagious viruses and non-infectious agents leading to a range of health problems, some of which can be fatal. There are five main strains of the hepatitis virus, known as types A, B, C, D and E. While their infection results in liver disease, they differ in important ways including modes of transmission, severity of the illness, geographical distribution and prevention methods. 

Particularly types B and C lead to chronic disease in hundreds of millions of people and together are the most common cause of liver cirrhosis, liver cancer and viral hepatitis related deaths. 

An estimated 354 million people worldwide having no access to testing and treatment live with hepatitis B or C. 

Some types of hepatitis are preventable through vaccination. A WHO study found that an estimated 4.5 million premature deaths could be averted in low-and middle- income countries by 2030 through vaccination, individual tests, drugs and education campaigns. WHO’s global hepatitis strategy, championed by all WHO Member States, aims to reduce new hepatitis infections by 90 and deaths by 65 between 2016 and 2030.

Hepatitis B is a potentially life-threatening liver infection caused by the hepatitis B virus (HBV). It can cause chronic infection and puts people at high risk of death from cirrhosis and liver cancer.
