Objective: 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 Zambe zia Province, Mozambique; in order to guide planning decisions about antiretroviral therapy (ART) program expansion. Methods: 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. Results: 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. Conclusions: 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.

In recent years, the worlds governments have galvanized
unprecedented support towards the scale-up of HIV care and
treatment. International programs such as the Presidents
Emergency Plan for AIDS Relief (PEPFAR) and the Global Fund to
Fight AIDS, Tuberculosis and Malaria have provided funding and
technical assistance for the successful initiation of large numbers of
patients on antiretroviral therapy (ART) in sub-Saharan Africa
and elsewhere. [14] The absolute number of persons with access
to and initiating ART is unprecedented (.10 million as of late
2013), yet key challenges remain to be addressed as to the quality
of services. Gaps include suboptimal awareness of personal HIV
status, late enrollment into HIV care and treatment, poor
adherence and retention strategies, minimal psychosocial support
initiatives, limited diagnostics of opportunistic infections, depleted
human resources for health, inadequate integration of HIV
services, and needs for health system strengthening. [1,410]
Each of these requires thoughtful, efficient, and evidence-based
health planning in order to have the desired impact.
Mozambique ranked 185 of 187 nations on the 2012 Human
Development Index of the United Nations Development Program
and was one of the original 15 PEPFAR focus countries. [11,12]
An estimated 2009 national adult HIV prevalence of 11.5% (,1.4
million HIV-infected persons aged 1549) ranked it among the
most heavily HIV-afflicted nations in the world. [13] The
magnitude of this epidemic is especially evident in Zambezia
Province, Mozambiques second largest province and home to 3.8
million persons. [5,6,13] While Mozambique ranks among the
poorest of the poor nations, Zambezia Province consistently ranks
among Mozambiques bottommost performing provinces with low
literacy rates, poor maternal and child health (MCH) indices, and
high rates of tuberculosis, malaria, and malnutrition. [1418]
More HIV-infected persons (,275,000) live in Zambezia than in
any other province, representing 20% of Mozambiques
HIVinfected adolescents/adults as of 2009 [13,19].
Estimating ART coverage rates for program planning purposes
has been difficult, mainly due to weaknesses in HIV surveillance
systems and in calculating HIV prevalence at a local site level.
From 1988 to 2009, Mozambique relied on bi-annual serosurveys
conducted at sentinel antenatal care (ANC) clinics (limited to 34
PMTCT clinics per province) for HIV prevalence estimates. [20]
In 2009, Mozambique implemented its first and only population
based National HIV epidemiologic survey, to date. [13] While
confidence in these methods of determining HIV prevalence has
increased, they continue to be limited to providing estimates for
national and regional levels only, and do not provide estimates for
the district or site level. Recently, there has been increasing
interest in the use of routine site level PMTCT data to supplement
or replace ANC sentinel surveillance an (...truncated)
