Summary
Active case detection (ACD) methods for leprosy screening vary by region. Tailoring these active case detection strategies to leprosy endemicity is crucial for reducing the global disease burden and achieving zero leprosy.
Area of Science:
- Public Health
- Infectious Disease Epidemiology
- Tropical Medicine
Background:
- Leprosy burden is unevenly distributed globally, with Brazil, India, and Indonesia reporting the majority of cases.
- Effective active case detection (ACD) strategies are essential for leprosy control programs.
- Understanding regional variations in ACD methods is key to improving global screening efforts.
Purpose of the Study:
- To systematically review and analyze active case detection methods for leprosy screening.
- To evaluate the applicability of these methods in high and low endemic regions.
- To inform the development of more effective future leprosy screening programs.
Main Methods:
- A systematic literature search was performed on PubMed, Embase, and Web of Science for papers published since 2000.
- English language papers detailing leprosy active case detection methods were included.
- The Integrated Screening Action Model (I-SAM) was used for analysis.
Main Results:
- Twenty-three papers from 11 countries were identified, detailing six distinct ACD methods.
- Methods included: household/social contact tracing, door-to-door screening, questionnaires, village surveys, school-based, and prison-based screening.
- Fifteen studies were from high endemic regions, and eight were from low endemic regions.
Conclusions:
- Leprosy endemicity must guide the selection of appropriate active case finding methods.
- Findings support policy decisions for designing successful future leprosy detection programs.
- Optimized ACD strategies can reduce the global leprosy burden and support the WHO's goal of zero leprosy.
