The majority of HIV transmission takes place between individuals via sexual contacts. At a population level, these partnerships can be viewed as connected into a dynamic sexual partnership network, whose structural and compositional characteristics influence, and are influenced by, the HIV epidemic. Although this is well understood, lack of data and a framework for utilising sampled network data and strategies for translating simulation findings into health promotion strategies has prevented the use of data-driven dynamic network mathematical models to inform the design of interventions in specific settings. The way that individuals seek and form sexual partnerships is changing in many settings, and so plausibly are the characteristics of the sexual partnership network. A rapid rise in the use of online social media is occurring not only in high income settings, but also in sub-Saharan Africa. It is now both critical and feasible to develop a framework for data-driven dynamic partnership network models of HIV transmission, to understand the intersection of HIV acquisition and transmission risk with online socialising and partner-seeking, and to ensure that HIV prevention and engagement in care interventions can be most effectively designed and targeted.A key group affected by HIV across the world is men who have sex with men (MSM), including in sub-Saharan Africa (SSA). Studies of MSM in SSA have found high HIV prevalence and incidence, alongside widespread experience of social stigma, violence, harassment and poor access to sexual health services. The incentives for MSM to socialise and seek partners online are high, and correspondingly, there is great potential to use online social media venues to provide information or referrals for in-person HIV prevention, testing and care services. This project will use unique and current data on sexual partnerships, online and offline-initiated, HIV status and engagement in care, and social media use from representative samples of MSM from Nairobi and Johannesburg to develop dynamic network models of HIV transmission, explore the potential role of social media use in HIV transmission, and bring networks-based insight to improve targeting of health promotion and inform intervention development and future research to reduce HIV incidence.

大多数艾滋病毒传播是通过性接触之间进行的。在人群层面上，这些伙伴关系可以被视为与动态的性伙伴网络有关，其结构和组成特征的影响，并受HIV流行的影响。尽管这是有充分理解的，但缺乏数据和用于利用采样网络数据和将模拟发现转化为健康促进策略的策略，这阻止了使用数据驱动的动态网络数学模型来告知特定设置中干预措施的设计。个人寻求和建立性伙伴关系的方式在许多环境中都在变化，因此，性伙伴关系网络的特征也是如此。在线社交媒体的使用迅速上升不仅在高收入环境中，而且在撒哈拉以南非洲。现在，为数据驱动的艾滋病毒传播的动态伙伴网络模型开发一个框架现在既关键又可行。 （SSA）。 SSA中MSM的研究发现，艾滋病毒的流行和发病率很高，以及对社会污名，暴力，骚扰和对性卫生服务的不良机会的广泛经验。 MSM在线社交和寻求合作伙伴的激励措施很高，相应地使用在线社交媒体场所提供信息或推荐以提供预防艾滋病毒的艾滋病毒，测试和护理服务。 This project will use unique and current data on sexual partnerships, online and offline-initiated, HIV status and engagement in care, and social media use from representative samples of MSM from Nairobi and Johannesburg to develop dynamic network models of HIV transmission, explore the potential role of social media use in HIV transmission, and bring networks-based insight to improve targeting of health promotion and inform intervention development and future research to reduce HIV incidence.
