About: World Hepatitis Day

World Hepatitis Day, observed on July 28 every year, aims to raise global awareness of hepatitis — a group of infectious diseases known as hepatitis A, B, C, D, and E — and encourage prevention, diagnosis and treatment. Hepatitis affects hundreds of millions of people worldwide, causing acute and chronic disease and killing close to 1.34 million people every year. Hepatitis can cause inflammation of the liver both acutely and chronically, and can kill a person. In some countries hepatitis B is the most common cause of cirrhosis and may also cause liver cancer. World Hepatitis Day is one of 11 official global public health campaigns marked by the World Health Organization, along with World Health Day, World Chagas Disease Day, World Blood Donor Day, World Malaria Day, World Immunization Week, World Tuberculosis Day, World No Tobacco Day, World Patient Safety Day, World Antimicrobial Awareness Week and World AIDS Day.
