World Hepatitis Day 2026 Observed on 28 July
World Hepatitis Day (WHD) is observed every year on 28 July to raise awareness about viral hepatitis and accelerate efforts to eliminate it as a public-health threat by 2030. The 2026 theme is 'Hepatitis: Let's Break It Down.' The date marks the birth anniversary of Dr. Baruch Samuel Blumberg, the Nobel laureate who discovered the Hepatitis B Virus (HBV) in 1967. The World Health Organization (WHO) officially designated 28 July as WHD in 2010 (Resolution WHA63.18), with the first WHO-recognised observance held in 2011. Hepatitis is inflammation of the liver, caused mainly by hepatitis viruses A, B, C, D and E.
