This research intended to profile specific determinants, which play an essential role in the transmission of TB in endemic slums, through the exploration of spatial characteristics in the affected households associated with factors and scientific evidence of high transmission settings. The study was conducted in two neighborhoods which are
endemic areas of TB, shaped after different informal urban development processes: ‘Barrios Altos’ and ‘San Cosme’ Hill. Despite the essential differences in their urban forms and historical backgrounds, these neighborhoods are taken as representative samples of the diverse urban morphology of the slums in Lima.
Direct relations of physical conditions with exposure and environmental factors for transmission are outlined, and specific high-risk settings in dwellings and collective housing buildings -and the possible influence of the urban formare pointed out, warning that external future stresses could worsen the situation. The over densification of dwellings and housing clusters are the side effects of decades of self-help-based and market-driven social housing policies, which did little to even health statuses in Lima. General solutions for the epidemic are proposed through physical upgrading, implying that improving such conditions could have potential benefits for residents' health. Modifications and new projects in consolidated slums could include three basic attributes for healthy environments: sunlight, ventilation, and space. However, other considerations should be taken for less-consolidated endemic slums, requiring further research with a comprehensive recognition of their realities. Any intervention to improve health would require changes in the current urban planning approach, urban policies, and actions to achieve socio-economic development. The thesis concludes that multi-level and multi-sectoral integrated development strategies are needed towards the construction of healthier neighborhoods in Lima, avoiding hygienist postures, forced evictions, and gentrification, to finally end the burden of TB.
