1984年9月对驻甬潜、快艇部队进行了调查。其调查及检测方法与前文(驻沪海军水面舰艇部队病毒性肝炎流行病学调查,《海军医学》3(3)1985)相同。现将本文主要数据报告如下。本次调查512人,其中海勤267人(潜艇164人,快艇103人),陆勤245人。受检的某潜艇支队1983年病毒性肝炎发病率为2.03‰;现患率为9.87‰。某快艇支队1983年病毒肝炎发病率为1.28‰;现患率为4.76‰,表明潜艇部队发病率及现患率均高于快艇部队。这一结果除可能与不同单位病毒性肝炎流行强度有关外,尚与卫生条件及劳动强度有关。驻甬潜、快艇部队HB_sAg阳性率为10.94％,抗—HBS阳性率为16.60％,抗—HBC
September 1984 in Ningbo submarine, speedboat forces were investigated. The investigation and testing methods are the same as the previous article (Epidemiological Investigation of Viral Hepatitis in Surface Forces of the Shanghai Navy and Surface Naval Force, 3 (3) 1985). Now the main data of this report is as follows. The survey of 512 people, including 267 people in the sea (submarine 164 people, speedboat 103), Lu Qin 245 people. The submarine submarine examined in 1983 the incidence of viral hepatitis was 2.03 ‰; the prevalence was 9.87 ‰. A speedboat detachment in 1983 the incidence of viral hepatitis was 1.28 ‰; prevalence was 4.76 ‰, indicating that the incidence and prevalence of submarine forces were higher than the speedboat forces. In addition to this result may be related to the prevalence of viral hepatitis in different units, but also with the health conditions and labor intensity. In Ningbo submarine, the positive rate of HB_sAg in speedboat troops was 10.94%, the positive rate of anti-HBS was 16.60%, anti-HBC
