本文介绍了用RPHA法检测舟山劳务输出(出国前)男性渔民631名,检出HBsAg阳性122名,阳性率为19.33%,比外地和本地其他人群携带水平高;不同船舶人群HBsAg阳性分布呈非均匀性。对渔民HBsAg高携带现象的原因作了初步分析。认为存在渔民因长期在船上的特殊生活条件和HBsAg阳性的炊事员引起传播的可能性,提出了渔民用餐实行分食制和加强炊事员疾病监测管理等防止乙型肝炎传播。 In this paper, 631 male fishermen from Zhoushan were surveyed by RPHA method. Among them, 122 were positive for HBsAg, the positive rate was 19.33%, which was higher than that of other local and other local populations. The positive distribution of HBsAg in different ships was non- Uniformity. The reasons for the high carrying of HBsAg in fishermen were analyzed. The author thinks that fishermen may spread their food because of their long-term special living conditions on the ship and the HBsAg-positive cooks. It proposed that the fishermen should adopt the catering system and strengthen the monitoring and management of the illnesses of the cooks to prevent the spread of Hepatitis B.
