To generate maps reflecting the intersection of community-based Voluntary Counseling and Testing (VCT) delivery points with facility-based HIV program demographic information collected at the district level in three districts (Ile, Maganja da Costa and Chinde) of Zambézia Province, Mozambique; in order to guide planning decisions about antiretroviral therapy (ART) program expansion.
Program information was harvested from two separate open source databases maintained for community-based VCT and facility-based HIV care and treatment monitoring from October 2011 to September 2012. Maps were created using ArcGIS 10.1. Travel distance by foot within a 10 km radius is generally considered a tolerable distance in Mozambique for purposes of adherence and retention planning.
Community-based VCT activities in each of three districts were clustered within geographic proximity to clinics providing ART, within communities with easier transportation access, and/or near the homes of VCT volunteers. Community HIV testing results yielded HIV seropositivity rates in some regions that were incongruent with the Ministry of Health's estimates for the entire district (2-13% vs. 2% in Ile, 2-54% vs. 11.5% in Maganja da Costa, and 23-43% vs. 14.4% in Chinde). All 3 districts revealed gaps in regional disbursement of community-based VCT activities as well as access to clinics offering ART.
Use of geospatial mapping in the context of program planning and monitoring allowed for characterizing the location and size of each district's HIV population. In extremely resource limited and logistically challenging settings, maps are valuable tools for informing evidence-based decisions in planning program expansion, including ART.
绘制地图，反映莫桑比克赞比西亚省三个区（伊莱、马甘贾达科斯塔和钦德）基于社区的自愿咨询检测（VCT）服务点与区级收集的基于机构的艾滋病毒项目人口信息的交集；以便指导抗逆转录病毒治疗（ART）项目扩展的规划决策。
从2011年10月至2012年9月为基于社区的VCT以及基于机构的艾滋病毒护理和治疗监测维护的两个独立开源数据库中收集项目信息。使用ArcGIS 10.1创建地图。在莫桑比克，为了坚持治疗和留存规划，通常认为在10公里半径内步行的距离是可接受的距离。
三个区中每个区基于社区的VCT活动都集中在提供抗逆转录病毒治疗的诊所附近、交通便利的社区内和/或VCT志愿者住所附近。社区艾滋病毒检测结果在一些地区产生的艾滋病毒血清阳性率与卫生部对整个区的估计不一致（伊莱为2 - 13%对2%，马甘贾达科斯塔为2 - 54%对11.5%，钦德为23 - 43%对14.4%）。所有三个区都显示出基于社区的VCT活动区域分布以及获得抗逆转录病毒治疗诊所服务方面的差距。
在项目规划和监测中使用地理空间映射能够描述每个区艾滋病毒感染人群的位置和规模。在资源极其有限且后勤保障具有挑战性的环境中，地图是为规划项目扩展（包括抗逆转录病毒治疗）提供循证决策的宝贵工具。
