Then there is hepB, which is over 50 times more infectious than HIV and often passed from mother to child before or shortly after birth, increasing the likelihood of liver cancer later in life. An estimated two billion people alive today have been infected with hepB, while 350 million people are chronically infected.
其次是乙肝，其传染性比艾滋病毒高50倍，通常在分娩之前或之后不久通过母婴渠道传播。乙肝会增加一生中患肝癌的可能性。据估计，如今在世者中有20亿人感染了乙肝，3 500万人为慢性。在这些人中，大约四分之一会死于与乙肝相关的癌症或肝硬化（慢性肝病的后果之一）。
