Abstract
Pulmonary Tuberculosis is the number one killer in South Africa. Although this is helped spurred on by the HIV/AIDS co-epidemic. We explored the effect of elevation in Tuberculosis transmission and mortality. Landsat 8 imageries were downloaded through earth-explorer and processed in Arc map 10.3. LULC maps generated from the satellite images were used for land characterization of provinces in South Africa. 3D DEM in Arc scene was utilized in displaying the elevation dataset. Our findings on the aggregate data at the provincial level could not show the association between elevation and Tuberculosis transmission and mortality.
Highlights
South Africa ranks just sixth in the world for a total number of Tuberculosis cases it has the second highest incidence rate of any country, with rates just barely lower than Lesotho [1]
The South African government released that the highest estimated prevalence rate of the latent Tuberculosis infection was around 88% was recorded in the age group 30-39 years in the dense populated urbanized areas [2]
Though multiple researchers have used elevation as part of their studies of Tuberculosis transmission as a covariable, none have looked at elevation as a prime contributing factor
Summary
South Africa ranks just sixth in the world for a total number of Tuberculosis cases it has the second highest incidence rate of any country, with rates just barely lower than Lesotho [1]. In the Northern Cape, the Tuberculosis incidence rate is 875 cases per 100,000 people, and the Tuberculosis mortality rate was 88 deaths per 100,00 cases [11]. The Eastern Cape is South Africa’s second largest province in terms of land area, encompassing nearly 168,966 km2 of territory.
