概括

扩大暴露前预防 (PrEP) 对高风险的HIV阴性男性和与台湾男性发生性关系的规模,可以消除艾滋病毒的流行. 这种策略具有成本效益,并且对遵守问题有强大作用.

科学领域:

公共卫生公共卫生
流行病学流行病学
数学建模的数学建模

背景情况:

到2030年全球艾滋病流行需要有效的干预措施,而PrEP的作用也在争论中.
台湾的艾滋病毒流行不成比例地影响了年轻的,性活跃的与男性发生性关系的男性 (MSM).

研究的目的:

在台湾建模高覆盖口服埃姆特里西塔宾/特诺福维尔PrEP的影响和成本效益.
评估PrEP在台湾MSM中消除艾滋病毒的潜力.

主要方法:

用于评估PrEP扩大规模对R0和HIV流行病轨迹的影响的随机和决定性建模.
模型与台湾国家艾滋病毒登记册和级联数据进行参数化.
从社会角度评估的成本效益.

主要成果:

仅仅一个强化艾滋病毒检测和治疗策略就不足以消除MSM中的艾滋病毒.
一个覆盖50%高风险,HIV阴性MSM的PrEP计划抑制了R0低于1,使其消除.
到2030年,PrEP显著降低了艾滋病毒发病率,使其低于世卫组织的消除值,效益成本比为7.16.
尽管有风险补偿,不完善的坚持或低水平的耐药性,但该计划的有效性仍然很强.

结论:

研究结果强烈支持在年轻,性活跃,高风险,HIV阴性MSM中扩大PrEP.
准备是结束台湾和全球HIV流行病的关键策略.

Retrovirus Life Cycles

Retrovirus Life Cycles

Retroviruses have a single-stranded RNA genome that undergoes a special form of replication. Once the retrovirus has entered the host cell, an enzyme called reverse transcriptase synthesizes double-stranded DNA from the retroviral RNA genome. This DNA copy of the genome is then integrated into the host’s genome inside the nucleus via an enzyme called integrase. Consequently, the retroviral genome is transcribed into RNA whenever the host’s genome is transcribed, allowing the...
