115/400 Muong minority pupils of boarding school in Hoa Binh province, all studied subjects have 3 genarations of Muong minority (grandparents, parents and themshelves being Muong minority), from 15 to 19 years old. Using Sero check product of USA to examine the ratio of HBsAg. Results: 19.05% of the boys having HBsAg(+), 13.38% of the girls having HBsAg(+). So the ratio of HBsAg(+) in girls are lower than in boys but it is not significant. The ratio of HBsAg(+) at the age of 15 is 19.61%, the age of 16-17 is 14.74% and the age of 18-19 is 16.67%, there is not significant between groups

The study has determined the seroprevalence and the risk factors of C and B hepatitis virus infection among cambodian patients visited to HCM city University Medical Centre. Results found an endemic prevalence of 19.74% of anti HCV(+) serum, anti-HBC(+) 74.84%, 15.84% HBsAg(+). 3.04% of anti-HCV(+) and HBsAg. Risk factors for HCV infection are concentration campain staying, traditional acupuncture, multiple sex partners injecting glass syringes.

Hepatitis B virus (HBV) infection has long been a critical public health challenge in China. National surveys revealed a prevalence of approximate 10% for chronic HBV infection in general population. HBV has been the leading cause of chronic hepatitis, cirrhosis, and liver cancers in Chinese population and a common pathogen of acute viral hepatitis. Meanwhile, the epidemic provided important opportunities to research the natural history, public health impact, and therapeutic and preventive interventions for HBV in China. In this review, we summarized the selected key epidemiological studies since 1970s regarding HBV infection and its associated liver diseases in China, and provided considerations for future research, prevention and treatment of HBV.

With the decline in hepatitis B virus (HBV) incidence and the increase in the life expectancy of infected individuals, the population infected with HBV is experiencing rapid aging, leading to an escalating risk of co-morbid chronic noncommunicable diseases (NCDs). This study summarizes research related to the comorbidity between HBV and NCDs, discussing the aging of the HBV-infected population, the mechanisms, prevalence, and management of this comorbidity. This study provides insights into potential directions for future research on the comorbidity between HBV and NCDs and aims to provide a basis for further research and the development of prevention and treatment strategies for the comorbidity of NCDs among HBV-infected individuals in China.

A study was conducted among 427 HIV-positive patients at Bach Mai hospital in 6 months early 2002. The results showed that: the rate of HIV- positive patients in anti-HCV positive group was 81.03%, the rate of HBsAg in HIV- positive patients was 18.26%. The rate of co-infection of Hepatitis C virus, Hepatitis B virus in HIV- positive patients was 14.9%. The rate of hepatitis C virus infection in HIV- positive persons infected through injecting drug use was 88.5%; in HIV- positive persons infected both through injecting drug use and sex was 83.67%. The rate of HIV- positive in patients infected through sex was 47.44%

Study was carried out on 22 HBsAg positive outpatients (14 males and 8 females, over 19 years old), all of them hadn't received any drug for hepatitis and HBV vaccine, and were treated at Central Military Hospital 108. All patients were treated with syrup of Hebevera 40ml twice a day. Results: syrup of Hebevera had possibilities of clearing HBsAg, HBeAg in patients' serum, stimulating immune system to produce antiHBe, protecting hepatic cells against necrotic inflammation, normalizing high ALT and AST. Beside, syrup of Hebevera has broad indications, no side-effects, and easy to use

A study was carried out on 737 seamen working in maritime transport companies at Hai Phong. The results showed that the prevalence of hepatitis B virus (HBV) infection among seamen was 54,86%, in which 15.57% were found to be positive with HbsAg and 39.29% positive with anti HBs. The HBV infection rate increased with age. The highest HBV infection rate was in 30 – 49 age group. Furthermore, the HBV infection rate increased with the number of years of service, and was highest when people had worked for 6 – 15 years. HBV infection rate among the seamen with good knowledge on hepatitis was likely lower than that of the seamen with inadequate or incorrect knowledge about hepatitis
