Project Summary Methicillin-resistant Staphylococcus aureus is a serious threat according to the Centers for Disease Control and Prevention (CDC), due to the increased morbidity and mortality among individuals who are infected with this pathogen.1 As a common healthcare- and community-associated pathogen, MRSA has a high burden of disease with over 300,000 cases and roughly 11,000 deaths in 2017.1 Though the overall rates of MRSA infection have been decreasing nationwide, this has not translated in communities of color, as the rates of healthcare-associated (HA), healthcare-associated community onset (HACO), and community-acquired (CA) MRSA is much higher among blacks compared to white individuals. 2–6In addition, we understand that jails have a disproportionately high prevalence rate of MRSA (19%) and a high proportion of people of color.7,8 Detainees have high rates of recidivism with about 76.6% of prisoners are rearrested within five years. 8 Once released, detainees interact with the community they came from prior entering the jail, resulting in potential transmission events. What is not well-understood is if jails themselves are an amplifier of MRSA community transmission. In this proposal, we will investigate the relationship between jail transmission of MRSA and the potential of transmission spillover into the wider community by utilizing genomic-based regression approaches and individual-based modelling. The results will elucidate how can jails amplify community transmission, especially among communities of color, and may perpetuate high rates of MRSA infections and/or colonization. Understanding this phenomenon will allow us to improve MRSA surveillance in these communities and design and increase targeted interventions in communities of color and within jails that potentially feed into their communities.

项目摘要 根据疾病中心的说法，耐甲氧西林金黄色葡萄球菌是一种严重的威胁 控制和预防（CDC），由于感染者的发病率和死亡率增加， 1作为一种常见的医疗保健和社区相关病原体，MRSA具有高负担， 2017年，MRSA的总发病率超过30万例，死亡人数约为11，000人。 感染率在全国范围内一直在下降，但这并没有转化为有色人种社区，因为 卫生保健相关（HA）、卫生保健相关社区发病（HACO）和社区获得性（CA） 与白色个体相比，MRSA在黑人中高得多。2- 6此外，我们知道监狱有 MRSA的患病率高得不成比例（19%），有色人种比例高。7，8被拘留者 累犯率很高，约76.6%的囚犯在五年内再次被捕。8一旦释放， 被拘留者在进入监狱之前与他们来自的社区互动，导致潜在的传播 事件目前尚不清楚的是，监狱本身是否是MRSA社区传播的放大器。 在这项建议中，我们将调查监狱传播MRSA和潜在的 通过利用基于基因组的回归方法， 基于个人的建模。结果将阐明监狱如何放大社区传播，特别是 在有色人种社区中，可能使MRSA感染和/或定植的高比率永久化。 了解这种现象将使我们能够改善这些社区的MRSA监测， 并增加对有色人种社区和监狱的有针对性的干预， 社区.
