可见大三阳和小三阳的区别主要在病毒复制活跃程度上，但并不表示“大三阳”一定比“小三阳”病情严重，临床研究证实，有些小三阳患者更容易转化为肝癌。在治疗上，如果是乙肝患者且HBVDNA含量高，大三阳和小三阳的区别不大，都要以抗病毒治疗为主，辅助抗炎保肝，抗纤维化治疗。Visiblebig3thisworldandsmall3thisworlddifferenceismainlyintheviralreplicationactivity,butitdoesn'tmeanthe"big3thisworld"than"small3thisworld"thediseaseissevere,clinicalstudieshaveconfirmedthatsomesmall3thisworldaremorelikelytobeconvertedintolivercancerpatients.Intreatment,ifishepatitisbpatientsandhbvdnacontenthigh,thedifferencebetweenbig3thisworldandsmall3thisworldisnotbig,togiveprioritytowithantiviraltherapy,anti-inflammatory,protectingliver,auxiliaryantifibrosistreatment.乙肝的传播途径

Thetransmissionwayofsecondliver血液传播（Bloodtransmission)：如输入被感染的全血、血浆、血清或其它血制品，或其他血源性注射传播。Suchasinputofwholeblood,plasma,seruminfectedorotherbloodproducts,orotherblood-bornespreadofinjection性传播(Sexuallytransmission)

：性滥交、同性恋和异性恋之间的亲密性行为是重要的乙肝病毒传播途径，这种传播亦包括家庭夫妻间的传播，夫妻之间的无防御措施的性行为传播率大概在14%左右，具体引人而异。因乙肝病人的唾液中可以查到乙肝病毒，在接吻时有可能会由于皮肤粘膜破损造成传染。因此在口腔有破损（如溃疡，咬伤，牙龈出血等）的情况下应避免与乙肝病毒携带者亲吻。Casualsexandintimacybetweenhomosexualandheterosexualsexisanimportantrouteoftransmission,hepatitisbvirusspreadthisalsoincludesthespreadoffamilyhusbandandwife,betweenhusbandandwife,withoutdefensemeasuresthesexuallytransmittedrateatabout14%,aboutthespecificvaries.Becauseofhepatitisbpatientssalivacangethepatitisbvirus,duringakissmaybecausedbydamagedskinandmucosainfected.Thusinthemouthisbroken(suchasulcers,bite,bleedinggums,etc.)ofthecasesshouldbeavoidedandkissthepersonthatsecondlivervirusiscarried.母婴传播(Mother-to-childtransmission)：母婴传播约占50％以上，其中宫内感染约占4.54%，其余为分娩时的感染；分娩时母亲的血液、阴道分泌物通过胎儿的破损皮肤、粘膜而传染；胎盘剥离时微量血液漏至胎循环中；产前或产程中胎儿吸入母亲的血液、羊水、阴道分泌物而感染；Mother-to-childtransmission(PMTCT)accountedforabout50%oftheabove,theintrauterineinfectionaccountedforabout4.54%,therestforchildbirthinfections;Birthmother'sblood,vaginalsecretionsinfectionbythebreakageofthefetalskin,mucousmembrane;Theplacentastrippingwhentracebloodleakageintothefetalcirculation;Antenatalfetalinhalationinthemother'sblood,amnioticfluid,orthestages,vaginalsecretionsandinfection;为何乙肝歧视问题如此“根固”？

Whyso"deep"hepatitisbdiscrimination?乙肝不通过消化道和呼吸道传播，所以日常接触如握手、拥抱、一起工作、吃饭等一般不会被乙肝病毒传播。但若和乙肝患者共餐的朋友有口腔溃疡等，与乙肝患者有血液暴露的接触，是有可能会传播乙肝病毒的。
