我国是乙型肝炎的高发区,从人群总体乙型肝炎病毒(HBV)感染率分析,大约10%的儿童也被HBV所感染。而在所有的肝炎病毒中,危害最大的是乙型肝炎病毒。因为感染后,个体可以成为无症状病毒携带者。新生儿期及3岁以下的婴幼儿感染后大多数成为表面抗原或病毒携带者,这些携带者中的一部分能发展成急、慢性乙型肝炎、肝硬化或肝癌。因为肝硬化和肝癌发展病程很长,大约需30-40年,故婴幼儿感染了乙型肝炎病毒并成为病毒携带者,发展成肝硬化和肝癌的可能性要大于成年人期乙型肝炎病毒感染。因此,采取有必要采取措施来尽量防治乙肝的恶化。本文就我国乙型肝炎病毒的研究现状及展望做简要介绍,以供参考。
China is a high incidence of hepatitis B, from the overall population of hepatitis B virus (HBV) infection rate analysis, about 10% of children are also infected with HBV. Of all the hepatitis viruses, the most harmful is the hepatitis B virus. Because after infection, individuals can become asymptomatic virus carriers. Most babies and children under the age of 3 and below become surface antigen or virus carriers. Some of these carriers can develop acute, chronic hepatitis B, liver cirrhosis or liver cancer. Because cirrhosis and liver cancer develop a long course of about 30-40 years, so infants and young children infected with hepatitis B virus and become a virus carriers, the possibility of developing cirrhosis and liver cancer is greater than the adult hepatitis B virus infection. Therefore, it is necessary to take measures to prevent and control the deterioration of hepatitis B as much as possible. This article gives a brief introduction about the current situation and prospect of hepatitis B virus in our country for reference.
