Viral hepatitis (A, B, C, D, and E) is the leading cause of inflammation of liver tissue (hepatitis). The disease burden associated with hepatitis A and E occurs shortly after infection; it is more severe among adults. With hepatitis A and E, the number of incident cases (new acute infections) is important from a public health perspective. Long-term hepatitis has been shown to cause cirrhosis and hepatocellular carcinoma in patients. The disease burden associated with hepatitis B, C, and D appears 10 to 20 years after infection. Thus, the prevalence of these infections is important from a public health perspective.
病毒性肝炎（A、B、C、D 和 E 型）是导致肝组织炎症（肝炎）的主要原因。甲型和戊型肝炎的疾病负担在感染后不久就会显现，且成年人的病情更为严重。从公共卫生的角度来看，甲型和戊型肝炎的新发感染病例数很重要。研究表明，长期的乙型、丙型和丁型肝炎会导致患者发生肝硬化和肝细胞癌。这些感染的流行率从公共卫生的角度来看很重要，因为它们出现在感染后 10 到 20 年。
