The correct answer is: World Hepatitis Day.
World Hepatitis Day is an awareness day observed on 28 July every year to raise awareness of viral hepatitis, a group of liver infections caused by five different viruses: hepatitis A, hepatitis B, hepatitis C, hepatitis D, and hepatitis E. The day was first observed in 2008, and is now celebrated by over 200 countries and territories.
Hepatitis is a serious disease that can lead to liver failure, cirrhosis, and liver cancer. It is estimated that over 2 billion people worldwide have been infected with hepatitis B or C, and that over 1 million people die from hepatitis-related causes each year.
World Hepatitis Day is an opportunity to raise awareness of hepatitis, its prevention, diagnosis, and treatment. It is also an opportunity to call for action to eliminate hepatitis as a public health threat by 2030.
