项目摘要
PROJECT SUMMARY
Current estimates are that 57% of persons in the U.S. with HIV are suppressed, leaving 43% unsuppressed,
including about 13% who are undiagnosed and 30% who have been diagnosed but are not currently
suppressed. Identifying persons with unsuppressed HIV to link them to care and antiretroviral treatment (ART)
is critical for improving health and reducing new infections. New epidemiologic tools that identify in real time
communities with high amounts of circulating HIV may enhance efforts to reduce HIV transmission and
substantially contribute to ending the HIV epidemic. During the SARS-CoV-2 (SCV2) pandemic, we and others
used “wastewater environmental virology” to monitor and respond to COVID. It uses viral capture and PCR
detection of viral nucleic acid from wastewater collection sites to detect, quantify, and predict total SCV2
activity in time. We built a robust and mature wastewater sampling program for the Houston region that
includes weekly assessment of 39 wastewater collection sites covering about 4 million residents. Our recent
preliminary data demonstrate that HIV is detected in wastewater. Wastewater testing is unbiased,
comprehensive, real-time, quantitative, and not influenced by access to health care, stigma or denial. We
hypothesize that our pioneering wastewater sampling program can be applied as a powerful new tool to
identify geographic areas with a high active burden of HIV, reflecting substantial numbers of people with
undiagnosed or untreated HIV infection. Resources can then be mobilized to these communities to enhance
HIV outreach, testing, prevention and linkage to care. The specifics aims are: 1) To develop a sensitive,
reproducible, and streamlined wastewater HIV detection pipeline; 2) To develop epidemiologic models
incorporating data from wastewater sampling as a novel and informative parameter along with routine
surveillance data on HIV diagnoses and population data; 3) To characterize and incorporate stakeholder
preferences, priorities, and recommendations for engaging key community stakeholders in the HIV wastewater
sampling program with consideration to the ethical, legal, social, and cultural contexts of individuals living in
target neighborhoods; 4) To determine if delivering proven public health interventions to neighborhoods as
directed by wastewater data can reduce the wastewater viral load and increase HIV diagnoses in those
neighborhoods. This research will enhance the Respond pillar of the End the HIV Epidemic (EHE) strategy. It
will leverage and strengthen partnerships between the researchers and the Houston Health Department, the
regional public health authority overseeing many EHE programs in Houston. The work in Houston, a high
priority EHE region, will result in: (i) the US’s only HIV wastewater sampling program, (ii) epidemiologic models
enhanced with wastewater data that identify unmet testing and treatment needs, (iii) community-informed and
ethically appropriate, real-time public health monitoring that reduces the number of people with unsuppressed
HIV, and (iv) tools and expertise that can be disseminated to other areas.
项目摘要
目前的估计是,在美国,57%的艾滋病毒感染者受到抑制,43%的人没有受到抑制,
包括约13%的未确诊患者和30%的已确诊但目前尚未确诊的患者
抑制确定未受抑制的艾滋病毒感染者,将他们与护理和抗逆转录病毒治疗联系起来
对于改善健康和减少新感染至关重要。真实的时间识别的新流行病学工具
艾滋病毒流行率高的社区可能会加强减少艾滋病毒传播的努力,
为结束艾滋病毒的流行做出了巨大贡献。在SARS-CoV-2(SCV 2)大流行期间,我们和其他人
使用“废水环境病毒学”来监测和应对COVID。它使用病毒捕获和PCR
从废水收集点检测病毒核酸,以检测、定量和预测总SCV 2
活动及时。我们为休斯顿地区建立了一个强大而成熟的废水采样计划,
包括每周评估39个废水收集点,覆盖约400万居民。我们最近
初步数据表明,在废水中检测到艾滋病毒。废水检测是公正的,
全面、实时、定量,不受获得医疗保健、耻辱或拒绝的影响。我们
假设我们开创性的废水采样程序可以作为一个强大的新工具,
确定艾滋病毒活动负担高的地理区域,反映大量艾滋病毒感染者,
未经诊断或治疗的艾滋病毒感染。然后可以向这些社区调动资源,
艾滋病毒宣传、检测、预防和与护理的联系。具体目标是:1)培养一种敏感的,
可重复的,简化的废水HIV检测管道; 2)开发流行病学模型
将废水采样数据作为一个新颖且信息丰富的参数沿着常规
艾滋病毒诊断监测数据和人口数据; 3)确定利益攸关方的特征并将其纳入
优先事项和建议,以使艾滋病毒废水中的关键社区利益相关者参与
抽样计划,考虑到生活在其中的个人的道德、法律的、社会和文化背景,
目标社区; 4)确定是否向社区提供经过验证的公共卫生干预措施,
由废水数据指导,可以减少废水中的病毒载量,
邻里关系这项研究将加强结束艾滋病毒流行战略的应对支柱。它
将利用和加强研究人员与休斯顿卫生部之间的伙伴关系,
地区公共卫生当局监督许多EHE计划在休斯敦。在休斯顿的工作,
优先EHE地区,将导致:(i)美国唯一的艾滋病毒废水采样计划,(ii)流行病学模型
通过废水数据得到加强,以确定未满足的测试和处理需求,㈢社区知情,
道德上适当的实时公共卫生监测,减少未受抑制的人数
艾滋病毒,以及(iv)可以传播到其他领域的工具和专门知识。
