Human immunodeficiency virus (HIV) causes AIDS.(人體免疫缺陷病毒(HIV)導致了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，抗逆轉錄病毒療法和7個癌癥的發生的相關性。)

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的反轉病毒。)

The likely impact of human immunodeficiency virus (HIV) infection on child mortality was also estimated from antenatal clinic surveillance data.(根據產前臨床監測數據，我們還對艾滋病毒感染對兒童死亡率可能產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，幾乎2%的艾滋病毒感染新發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。)
