传染性

HBV-DNA content shows a negative correlation with age, and males show a higher HBV-DNA content than that in females. HBV-DNA detection is contribute to the judgment of infectiousness of HBV infected individuals and the evaluation of clinical effect of anti-virus drugs and further to decide the best therapeutic scheme.

HBV-DNA含量与年龄呈负相关；HBV-DNA含量男性明显高于女性；乙肝患者应做HBV-DNA检测，有助于HBV感染者传染性大小的判断以及对抗病毒药物临床疗效的评价，以确定最佳治疗方案。

But all of the TS and APE were negative stained for HBV-DNA.Conclusion:Many TS and APE had been polluted in the infection hospital.But they maybe have less infectiousness.

传染病医院的组织切片、病理申请单有相当数量被HBV污染，但传染性较小。

Additionally, HIV is unable to reproduce outside its living host (unlike many bacteria or fungi, which may do so under suitable conditions), except under laboratory conditions, therefore, it does not spread or maintain infectiousness outside its host.

再者，HIV病毒在离开期生存环境后不能自行繁殖(不象其他许多细菌或真菌可以在合适的条件下繁殖)，除非在实验室培养的条件下。所以HIV离开载体不能自行分裂和保持传染性。

PreS1 could be taken as a new serological indicator for infectivity and replication of HBV.

PreS1可以作为一项新的乙肝病毒复制的传染性指标。

Positive of the HBsAg in serum expresses hepatitis B virus infection, have certain infectivity.

血清中HBsAg阳性表示乙型肝炎病毒感染，有一定的传染性。

Inchoate infection of virus of diagnostic second liver and infectivity, already made the collective wish of people.

早期诊断乙肝病毒感染及传染性，已成为人们的共同愿望。

The virus has such high infectivity that it soon spread to the whole area.

这病毒传染性如此强，不久就传遍整个地区。

Further, the infectivity is highly resistant to radiation and other treatments that normally inactivated viruses.

而且，这种传染性对辐射和常规病毒灭活手段有很强的抵抗力。

Diabetes is a familiar chronic disease without infectivity.

糖尿病是一种常见的慢性非传染性疾病。

More or less may a lot of student look for the demand of able person, but they are a groups, infectivity is very strong.

The split between the two groups can hardly be papered over.
