3Project Background
- Planning and implementing accelerated treatment
programmes require the information about the
prevalence of sufferers and patients to be
targeted by remedial action. - This requires locational data.
- Specific actions require specific locations.
- With intranational variance in disease, finer
resolution data is required to formulate
geographically targeted interventions at
sub-national level. - HIV/AIDS exhibits this intranational variance and
treatment programmes need geovisualisation tools. - HIV/AIDS responses also require statistics and
analytics at a sufficiently disaggregated
geographic unit. - Therefore ECA and EIS-AFRICA are working together
to develop disaggregated sub-national data on
HIV/AIDS according to SALB boundary
specifications and protocols.
4T.O.R of study
- UN-ECA contracted EIS-AFRICA in February 2009 to
undertake a study to support the collection and
processing of sub-national boundary data,
presented in GIS along with disaggregated
HIV/AIDS data for priority countries. - Countries
- Angola
- Botswana
- Lesotho
- Malawi
- Mozambique
- Namibia
- Tanzania
- Swaziland
- Zambia
- Zimbabwe
- Production of a GIS-based HIV/AIDS database (data
inventory, docs studies etc.)
5Methodology
- Conduct a data inventory of SALB and HIV data at
district level for 10 priority countries. - Identify key national partners
- NMAs
- National Ministries /HIV/AIDS Health councils
- Identify key international partners
- WHO (SALB), ECA (SALB) USAID, UNAIDS, Macro
International (field survey for Demographic
Health Survey (DHS) with is done nationally but
sponsored internationally) - HIVspatialdata.net (DHS repository spatial, shp
files, metadata) etc. - Identify regional partners
- SAHIMS, SARDC, Southern African HIV AIDS
dissemination service (SAfAIDS) etc. - Contracted relevant partners
- Desktop study (telephonic interviews, web-based
research etc.)
6Outputs
- Process, integrate, harmonise, validate and
geocode data received - Create Maps using ArcView 9.2
- Develop a thesaurus of metadata indicating the
source, location, format, storage mode, status,
quality, nature of use etc. - Present interim report at CODIST 1.
- Update information (NMA and NHM)
- Prepare a comprehensive report of study (identity
data gaps).
7HIV/AIDS in Southern Africa
- Southern Africa remains the global epicentre of
the HIV/AIDS pandemic. - In 2007, the region accounted for 35 percent of
all people living with HIV worldwide and 32
percent of the worlds new HIV infections and
AIDS deaths. - According to UNAIDS, in 2005, eight countries in
southern Africa (Botswana, Lesotho, Mozambique,
Namibia, South Africa, Swaziland, Zambia, and
Zimbabwe) had a national adult HIV prevalence
higher than 15 percent. - Prevalence rates in the region have for the most
part levelled off. Although Swaziland, Zambia,
and Zimbabwe appear to have had significant
declines in prevalence, UNAIDS cautions that the
extent of these declines is not clear due to
inconsistencies in the data.
8Second Admin Level Boundary (SALB)
- The Second Administrative Level Boundaries data
set project (SALB) has been launched in 2001 in
the context of the activities of the UN
Geographic Information Working Group (UNGIWG) and
has for objective to provide free access
(non-commercial use) to a working platform for
the collection, management, visualization and
sharing of sub national data and information. - Its original objective, was to provide the
international community with a global
standardized GIS layer containing the
delimitation of the administrative boundaries
down to the 2nd sub national level.

12DHS, MapLibrary and SALB
- The Map Library is a source of public domain
basic map data concerning administrative
boundaries in developing countries. The data is
broken down into manageable chunks to make it
easier to download for those with poor internet
connections. www.maplibrary.org - http//www.hivspatialdata.net metadata available

28Country issues 1
- Mozambique Don't have HIV data for all
Districts. Have SALB from NMA. HIV that we have
is not stratified by Gender Age. - Botswana Have all HIV data at District level.
Need data by Age at District level at the moment
only available nationally by Age. Need national
SALB for NMA. We got the data now! - Angola no SALB from NMA! No HIV data at
district level. - Lesotho received SALB from NMA but no HIV data
at district (constituency) level! They have it
but we havent received it. We can provide
analysis by age and gender at provincial (Lesotho
district level) - Malawi DHS survey, National sentinel survey
(National AIDS commission), SALB boundaries, no
national source of district boundaries.
29Country issues 2
- Namibia Reports at Health District level which
doesn't correspond to NMA admin 2 boundaries or
SALB. Reporting only by total population and
pregnant women. HDL shape files not available.
SALB (Admin 2) and NMA boundaries don't match. - Swaziland Admin2 boundaries from MapLibrary.
Provincial boundaries from DHS and NMA. NMA will
be sending official boundaries. HIV data only at
provincial level both by Age and Gender. - Tanzania Provincial HIV Data for gender and
Age. Have Admin2 boundaries from Ministry of
Lands and Map Library. Boundaries don't
correspond. - Zambia Boundaries for admin2 from SALB. No NMA
boundaries. HIV prevalence at District level
from UNAIDS only in total population. Also have
DHS at provincial level. (WHO has done study). - Zimbabwe DHS at Provincial level. SALB
boundaries. No HIV statistics at Admin2 level.
30Lesson learnt
- HIV reports are at provincial level
- Health departments rely on international agencies
to undertake surveys. - By of total population (males/females etc.)
- By Pregnant women (antenatal centres)
- No communication between NMAs and Health
Departments - No national health facilities surveys.
- Few countries have health facilities geo-coded.
- Census data is required.
- Barriers from health department reporting (stigma
etc.)
31Lessons Learnt continued
- Boundaries are questionable.
- National ministries have different boundaries
(health, lands etc.) - HIV districts don't match SALB place names.
- Terminology District Province etc.
- NSDI non existent (issues driven SDI).
- Metadata at from national agencies are non
existent. - Central repository of HIV at District level and
national DHIS (HIV, TB etc.) is needed. - Health networks (NHD, HIV NGOs, MNAs)
- An integrated Disease Surveillance System is
needed for all infectious diseases. - NMAs send me your SALB!!!!! (You must support the
SALB initiative)
32Conclusion
- Geographic information and their related systems
and infrastructure are essential components in
ME Health issues. - However, constraints to mapping health
information include - Spatial Data (collection, availability, acquiring
and sharing) - Resources (Overall personal, finances etc.)
- Awareness (collaboration and cooperation)
- HIV data (facilities level, spatialised,
availability, shared and accessible) - Standards (metadata)
33Geospatial technologies can integrate data and
gives us strength for deeper analysis.... It
gives a common perspective.... It can transform
the way we look at issues.... because its
visual its helps people to see.....gives people
access to knowledge that dont have formal
education. (Prof. Lidia Brito, CODIST 1, 2009)
