Summary
Spatial analysis of leprosy in Olinda, Brazil, revealed a strong correlation between social deprivation, income, and disease distribution. This finding enables targeted public health interventions for leprosy control.
Area of Science:
- Epidemiology
- Spatial Analysis
- Public Health
Context:
- Leprosy in Pernambuco, Brazil, is predominantly an urban disease with uneven geographical distribution.
- Urban spatial transformation influences leprosy's epidemiological patterns.
- Spatial analysis offers a valuable tool for leprosy surveillance.
Purpose:
- To define homogeneous micro-areas in Olinda using census and SINAN data.
- To classify census tracts by social deprivation index (SDI) and income.
- To analyze the association between socioeconomic factors and leprosy detection rates.
Summary:
- Homogeneous micro-areas were created by integrating census and SINAN data with geoprocessing.
- Social deprivation index (SDI) and income were used to stratify risk.
- A strong association (r2=84.3%) was found between income and leprosy detection rates (1991-1996).
- Census tracts were categorized into high, moderate, and low risk levels for targeted interventions.
Impact:
- The methodology successfully identified high-risk areas and population groups for leprosy within health districts.
- Enabled the definition of tailored control measures and intervention strategies.
- Provides a framework for enhanced epidemiological surveillance and resource allocation for leprosy control.
