Assessing the essential components of '1-3-7' strategy along the China-Myanmar border is critical to identify gaps and challenges to support evidence-based decision making.
A mixed-method retrospective study including quantitative and qualitative analysis of the 1-3-7 system components was conducted. Sampled counties were chosen based on malaria incidence from 1 January 2012 to 31 December 2014.
All 260 confirmed malaria cases from sampled counties were reported within 1 day and had completed case investigations. 70.0% of all Reactive Case Detection (RACD) events were conducted and 90.1% of those were within 7 days. Only ten additional individuals were found malaria positive out of 3662 individuals tested (0.3%) by rapid diagnostic test during RACD events.
Key gaps were identified in case investigation and RACD activities in Yunnan Province border counties. This evidence supports improving the RACD (or "7") response strategy in this setting. Given the challenges in this border region, it will be critical to adapt the RACD response to promote the malaria elimination along the China border.
评估中缅边境地区“1-3-7”策略的基本组成部分对于识别差距和挑战以支持循证决策至关重要。
开展了一项混合方法的回顾性研究，包括对“1-3-7”系统组成部分进行定量和定性分析。根据2012年1月1日至2014年12月31日的疟疾发病率选择抽样县。
抽样县的所有260例确诊疟疾病例均在1天内报告并完成了病例调查。所有主动病例检测（RACD）活动的70.0%已开展，其中90.1%在7天内完成。在RACD活动期间，通过快速诊断检测对3662人进行检测，仅另外发现10人疟疾呈阳性（0.3%）。
在云南省边境县的病例调查和RACD活动中发现了关键差距。这一证据支持在该地区改进RACD（即“7”）应对策略。鉴于该边境地区存在的挑战，调整RACD应对措施对于推动中国边境地区消除疟疾至关重要。
