In 1987, 676 blood samples were collected from inhabitants of the Bhadrakali and Kotyang villages in Nepal. The samples were tested for the prevalence of antibody to hepatitis A virus (anti-HAV), hepatitis B surface antigen (HBsAg), antibody to hepatitis B core antigen (anti-HBc), second-generation antibody to hepatitis C virus (anti-HCV) and antibody to human T-lymphotropic virus type-I (anti-HTLV-I). Anti-HAV was present in 99.3% of the people surveyed. The prevalence of anti-HAV reached 100% in the < 25 age group and was as high or only slightly lower in all other age groups. The prevalence of HBsAg was 0.3% and of anti-HBc 7.7%. Anti-HCV was found in 0.1% of the residents. No significant difference by gender or village was noted in the prevalence of anti-HAV, HBsAg, anti-HBc, or anti-HCV. No anti-HTLV-I-positive persons were identified. These data suggest that the prevalence of hepatitis B and C virus infections in Nepal is low in contrast to hepatitis A virus infection, and that human T-lymphotropic type-I infection may be absent in this population.
1987年，从尼泊尔巴德拉克利村和科蒂扬村的居民中采集了676份血样。对这些血样进行了甲型肝炎病毒抗体（抗-HAV）、乙型肝炎表面抗原（HBsAg）、乙型肝炎核心抗原抗体（抗-HBc）、丙型肝炎病毒第二代抗体（抗-HCV）和人类嗜T淋巴细胞病毒I型抗体（抗-HTLV-I）的流行率检测。99.3%的受调查者体内存在抗-HAV。在<25岁年龄组中，抗-HAV流行率达到100%，在所有其他年龄组中也同样高或仅略低。HBsAg流行率为0.3%，抗-HBc流行率为7.7%。在0.1%的居民中发现了抗-HCV。在抗-HAV、HBsAg、抗-HBc或抗-HCV的流行率方面，未发现性别或村庄之间存在显著差异。未发现抗-HTLV-I阳性者。这些数据表明，与甲型肝炎病毒感染相比，尼泊尔乙型和丙型肝炎病毒感染的流行率较低，并且该人群中可能不存在人类嗜T淋巴细胞病毒I型感染。
