非洲HBV感染率很高,人群中HBsAg(+)者亦增高至8％～15％,而欧洲及北美洲仅0.1％～0.5％,此病毒的慢性携带者使肝细胞癌的发病率增加。非洲首位恶性肿瘤就是肝癌,其发病率为20～150/100000,而欧洲仅10/100000,而且主要是年轻患者。20～50岁。要预防肝癌,首先要控制乙肝及HBV不同方式的传播。HBsAg慢性携带者亦能在围产期垂直传播。在刚果此携带者估计有9.6％,肝癌占恶性肿瘤中的首位,但对HBV传播的研究却没有,本研究主要目的是:①刚果孕妇HBV的测定;②估计母儿垂直传播的发病率。
In Africa, the rate of HBV infection is very high. The population of HBsAg (+) is also increased to 8% to 15%, while in Europe and North America only 0.1% to 0.5%. The chronic carriers of this virus increase the incidence of hepatocellular carcinoma. The first malignant tumor in Africa is liver cancer, its incidence is 20 ~ 150/100000, while Europe only 10/100000, and mainly young patients. 20 ~ 50 years old. To prevent liver cancer, we must first control the spread of hepatitis B and HBV in different ways. Chronic HBsAg carriers also spread vertically during the perinatal period. In the Congo this carrier is estimated to have 9.6%, liver cancer ranks first in malignant tumors, but no study of HBV transmission, the main purpose of this study are: ① Congo pregnant women HBV determination; ② estimate the incidence of mother-child vertical transmission.
