世界肝炎日——2011年7月28日
世卫组织首个正式的世界肝炎日，是要提高人们对病毒性肝炎及其引起的疾病的认识和了解。
这一天是重点关注一些具体行动的机遇，比如：加强病毒性肝炎及其相关疾病的预防、筛查及控制；提高乙肝疫苗的覆盖率并将其纳入到国家计划免疫规划之内；以及协调全球对肝炎做出的应对。

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.
