Feasible epidemiological approaches are required to make a better assessment of the stage of an epidemic and to monitor its transition through various phases. Application of the Lorenz curve and Gini coefficient to summarise the inequality in STD incidence rates between jurisdictions in Manitoba, Canada, was found to provide useful insights into the concentration of these epidemics over time and thus their transition through epidemic phases. Further exploration of the statistical properties of these and other indices of inequality and their potential application to STD epidemiology is warranted. New epidemiological tools are also required for better monitoring of the impact of prevention and control activities and to inform the content of these activities.
需要可行的流行病学方法来更好地评估疫情阶段，并监测其在各个阶段的转变。研究发现，应用洛伦兹曲线和基尼系数来总结加拿大曼尼托巴省各辖区性传播疾病发病率的不平等情况，有助于深入了解这些疫情随时间的集中程度，从而了解它们在疫情各阶段的转变。有必要进一步探索这些不平等指数及其他指数的统计特性及其在性传播疾病流行病学中的潜在应用。还需要新的流行病学工具来更好地监测预防和控制活动的影响，并为这些活动的内容提供依据。
