The history of the HIV epidemic and the response to the epidemic is fundamentally a history of an emergency response to a global crisis. Trends and projections from initially available data were instrumental in establishing the President's Emergency Plan for AIDS Relief (PEPFAR) and in determining the direction of the program. Additionally, PEPFAR was built on data and the potential impact of interventions, and required the constant monitoring of the epidemic to report on the progress of the program. The response to the HIV epidemic saw the development of international guidelines and recommendations for data collection and epidemiological modeling. Although it is true that the urgency of the response often meant that data from data-poor countries suffered from incompleteness and bias, fortunately, as the response matured, the quality of the data and the infrastructure supporting data collection also matured. PEPFAR investments in surveillance and surveys were and remain critical for responding to the epidemic. The future of the response is reflected in growing country capacities to collect valid and reliable data, and using those data for decision making.
艾滋病毒疫情的历史和对疫情的应对从根本上说是对全球危机的紧急应对的历史。最初可用数据的趋势和预测对设立总统艾滋病紧急救援计划（PEPFAR）和确定方案方向起到了重要作用。此外，PEPFAR 是建立在数据和干预措施的潜在影响之上的，需要对疫情进行持续监测，以报告方案的进展情况。对艾滋病毒疫情的应对促使制定了国际准则和建议，以进行数据收集和流行病学建模。虽然应对疫情的紧迫性通常意味着数据匮乏国家的数据存在不完整性和偏差，但幸运的是，随着应对措施的成熟，数据的质量和支持数据收集的基础设施也得到了改善。PEPFAR 在监测和调查方面的投资对于应对疫情至关重要。应对措施的未来反映在各国不断增强的收集有效和可靠数据的能力，以及利用这些数据进行决策的能力上。
