    ¡¾Abstract¡¿ AIM: To explore the epidemic situation, epidemic serotype of hepatitis and its trend of prevalence in the military forces, so as to guide the disease prevention and control. METHODS: We collected and analyzed the epidemiological data on hepatitis in the calendar years 1957-2005 of the troops and examinated some serum samples. ELISA was used to detect the indicators of hepatitis A, C, D and E and RIA was employed to detect the indicators of hepatitis B. RESULTS: The sporadic cases of hepatitis were mostly found in the calendar years, occasionally the localized cases were seen. The incidence rate fluctuated about 2¡ë before 1980, reached the highest in 1969(3.54¡ë), declined steadily since 1981 to 0.11¡ë in 1995, and wandered about 1¡ë in 1996-2005. Among the 5 kinds of hepatitis, type A was controlled in the incidence and type B was relatively most frequent. The soldiers have a high incidence rate of over 50%. CONCLUSION: In the prevention and control of hepatitis, we should focus our attention on hepatitis B. Of course, the prevention against hepatitis A should not be ignored. ......
