Human immunodeficiency virus (HIV) causes AIDS.(人體免疫缺陷病毒(HIV)導(dǎo)致了AIDS。)

AIDS is thought to have originated in Africa, where monkeys and apes harbor a virus similar to HIV called SIV (simian immunodeficiency virus).(艾滋病被認為起源于非洲，那里的黑猩猩和猿攜帶了一種類似HIV的病毒，叫SIV(猴免疫缺陷病毒)。)

The study authors also analyzed the association between immunodeficiency, viral load, antiretroviral treatment and the onset of the seven cancers.(該研究的作者還分析了免疫缺陷，病毒載量，抗逆轉(zhuǎn)錄病毒療法和7個癌癥的發(fā)生的相關(guān)性。)

Human immunodeficiency virus (causes AIDS).(人類免疫缺陷病毒(造成艾滋病)。)

The human immunodeficiency virus (HIV) is a retrovirus that infects cells of the human immune system, destroying or impairing their function.(人類免疫力缺乏病毒（HIV）是一種感染人類免疫細胞，從而破壞人體免疫系統(tǒng)的反轉(zhuǎn)病毒。)

The likely impact of human immunodeficiency virus (HIV) infection on child mortality was also estimated from antenatal clinic surveillance data.(根據(jù)產(chǎn)前臨床監(jiān)測數(shù)據(jù)，我們還對艾滋病毒感染對兒童死亡率可能產(chǎn)生的影響做出了估計。)

Human immunodeficiency virus: Globally nearly 2% of all new HIV infections are caused by unsafe injections.(人類免疫缺陷病毒：在全球范圍內(nèi)，幾乎2%的艾滋病毒感染新發(fā)病例是因不安全的注射而造成的。)

It was later named the human immunodeficiency virus.(它在后來被命名為人類免疫缺陷病毒。)

The human immunodeficiency virus (HIV) infects cells of the immune system, destroying or impairing their function.(人類免疫缺陷病毒(HIV，也稱艾滋病毒)感染免疫系統(tǒng)細胞，破壞或損傷其功能。)

Depending on the cause treatment for immunodeficiency may be administration of immunoglobulins bone-marrow transplant or therapy for the underlying disease.(免疫不全的治療取決于病因，可能要使用免疫球蛋白，骨髓移植或是對造成免疫不全的疾病作根本治療。)
