*Factors that may increase the risk of HIV transmission include sexually
transmitted diseases, acute and late-stage HIV infection, and high viral
load. Factors that may decrease the risk include condom use, male
circumcision, antiretroviral treatment, and pre-exposure prophylaxis. None of
these factors are accounted for in the estimates presented in the table.
有些因素可能会增加HIV传播的风险，包括其他性病、急性与晚期HIV感染、高病毒载量。
有些因素可能会降低HIV传播的风险，包括使用保险套、割包皮、抗反转录病毒药物与
接触前预防。
这些因素都没有纳入上表的计算中。
