%X 对长期被公认的“乙肝病毒不通过饮食传染，是一种血液传染病”的论断提出质疑，并提出相反的即乙肝病毒主要通过饮食传染的假设：在正常情况下，当人体免疫力及消化功能正常时，即便乙肝病毒随饮食进入消化道内，消化液也会将乙肝病毒杀死，故乙肝病毒不会进入人体血液之中，但是，如果当人体患上呼吸道感染致抵抗力下降，或当胃肠道受感染导致胃肠功能紊乱、消化液分泌失常时，随不洁饮食带入到消化道内的乙肝病毒就可能由于体内消化液的分泌失常而存活，并可能乘机进入人体血液中而致病。<br>A long-time recognition that hepatitis B virus (HBV) is not contagious through diet but a blood-bornedisease is questioned in this paper. The author puts forward a contrary theory that HBV infection happens mainly throughdiet. In general conditions when the body’s immune and digestive functions are normal, even if HBV is carried withdiet into people’s digestive tracts, digestive juice will kill it, hence HBV is not able to enter the blood streams. But if thebody is suffering from respiratory tract infection with decreased resistance or when gastrointestinal infection leads togastrointestinal disorders and digestive juice secretion disorders, HBV would be most probably carried with diet into thedigestive tract, and due to disordered digestive juice secretion that fails to kill the HBV, it is possible for the HBV to gointo the human blood streams, as a result, the people would be infected. It is estimated that the probability of HBV spreadthrough diet is much larger than that by blood and body fluid, so people are warned to maintain vigilance and develop goodhealth habits to prevent HBV from entering the digestive tract
