论文摘要
我们创建了一个网络模型,通过在城市中的身体接近和意外的每日人类接触来研究流行病的传播,并为两种代理人(贫穷和无贫困)模拟结果。在非干预下,夏壳峰值最大化,但在贫困和非贫困中没有观察到的感染率差异。在所有情况下,引入了控制扩散的干预措施以控制扩散,降低峰值壳量,但累积感染率和当前感染率在系统上都高于非贫困者。发现较大的人群,较高的贫困部分和更长的干预持续时间会逐渐恶化穷人的结果。对于发展中国家城市的经济脆弱人群,这些尤其关注。应对这些挑战需要对结构性贫困与流行之间的关系有更深入,更严格的了解,并有效利用现有的社区层面基础设施来发展发展中心的初级保健。最后,改善穷人的纯粹结果为包括贫困者在内的整个人群带来了更好的结果。
We create a network model to study the spread of an epidemic through physically proximate and accidental daily human contacts in a city, and simulate outcomes for two kinds of agents - poor and non-poor. Under non-intervention, peak caseload is maximised, but no differences are observed in infection rates across poor and non-poor. Introducing interventions to control spread, peak caseloads are reduced, but both cumulative infection rates and current infection rates are systematically higher for the poor than for non-poor, across all scenarios. Larger populations, higher fractions of poor, and longer durations of intervention are found to progressively worsen outcomes for the poor; and these are of particular concern for economically vulnerable populations in cities of the developing world. Addressing these challenges requires a deeper, more rigorous understanding of the relationships between structural poverty and epidemy, as well as effective utilization of extant community level infrastructure for primary care in developing cities. Finally, improving iniquitous outcomes for the poor creates better outcomes for the whole population, including the non-poor.
