世界肝炎日——2011年7月28日
世衛組織首個正式的世界肝炎日，是要提高人們對病毒性肝炎及其引起的疾病的認識和了解。
這一天是重點關注一些具體行動的機遇，比如：加強病毒性肝炎及其相關疾病的預防、篩查及控製；提高乙肝疫苗的覆蓋率並將其納入到國家計劃免疫規劃之內；以及協調全球對肝炎做出的應對。

背景資料
乙型肝炎病毒圖片(來自CDC):
Hepatitis means inflammation of the liver. Toxins, certain drugs, some diseases, heavy alcohol use, and bacterial and viral infections can all cause hepatitis. Hepatitis is also the name of a family of viral infections that affect the liver; the most common types in the United States are hepatitis A, hepatitis B, and hepatitis C.
Hepatitis B is caused by infection with the Hepatitis B virus (HBV). The incubation period from the time of exposure to onset of symptoms is 6 weeks to 6 months. HBV is found in highest concentrations in blood and in lower concentrations in other body fluids (e.g., semen, vaginal secretions, and wound exudates). HBV infection can be self-limited or chronic.
