...患者的血中的病毒量已无法用仪器检测得到，且CD4淋巴球数升高，因此大幅地降低了病患发生伺机性感染（opportunistic infections）和肿瘤的机会与致死的风险。但这并不等于治愈。

HIV invades immune system, so AIDS patients almost died of opportunistic infection.
因HIV侵袭免疫系统，AIDS病人最终多因机会性感染而死亡。

These genes might be related with bacterial opportunistic infection.
本研究利用差异荧光诱导技术(differential fluorescence induction, DFI),在体内大规模地筛选鉴定肺炎链球菌受转化调控的毒力基因,这些基因很可能是肺炎链球菌条件致病过程中的重要基因。

TB occurs earlier in the course of HIV infection than many other opportunistic infections.
与许多其他机会感染相比，结核病在HIV感染过程中出现较早。
Opportunistic infections such as toxoplasmosis, MAC and cytomegalovirus infection can be diagnosed and treated in places with advanced infrastructure.
而其他的机会感染，如弓形体病、鸟型结核菌感染和巨细胞病毒感染等机会需要在具备先进基础设施的地方才能进行诊断与治疗。
For people who have already contracted an opportunistic infection and undergone successful treatment, secondary prophylaxis may be advisable to prevent recurrence.
对于曾经患过机会感染和并有成功的治疗的人，推荐使用二线预防，以防止复发。
