Hepatitis B is an infectious disease, which can also be transmitted by contact. Blood and secretory products of the body may be infectious. The extent and mode of contact as well as the quantity of infectious agents probably are responsible for the extent and course of the disease. Morbidity of hepatitis B is known: hepatitis B still is acquired in most cases by inoculation or blood transfusion. There seems to be a subclinical epidemic process mainly due to contact infection: the extent of this process can at the best only be estimated. The role of the different secretory products of the body in this process has not yet been clarified.
乙型肝炎是一种传染病，也可通过接触传播。人体的血液和分泌产物可能具有传染性。接触的程度和方式以及传染源的数量可能决定了疾病的范围和病程。乙型肝炎的发病率是已知的：在大多数情况下，乙型肝炎仍然是通过接种或输血感染的。似乎存在一个主要由接触感染引起的亚临床流行过程：这个过程的范围充其量只能估计。人体不同分泌产物在这个过程中的作用尚未阐明。
