Summary
Leprosy affects 3.9 per 1000 students, with higher rates in males and Tamil/Urdu speakers. Most cases are early-stage, non-lepromatous, and without deformity, indicating potential for effective early detection in student populations.
Area of Science:
- Epidemiology
- Dermatology
- Public Health
Background:
- Leprosy remains a public health concern, particularly in school-aged populations.
- Early detection and treatment are crucial for preventing disability and transmission.
Purpose of the Study:
- To determine the prevalence and characteristics of leprosy among students.
- To identify risk factors associated with leprosy in this demographic.
Main Methods:
- Cross-sectional study involving the examination of 55,502 students.
- Data collection on leprosy cases, including demographic information and clinical presentation.
Main Results:
- A case-detection rate of 3.9 per 1000 students was observed.
- Leprosy was significantly more common in male students and those speaking Tamil or Urdu.
- The majority of cases (98%) were the tuberculoid type, with 86% in early stages and over 99% without deformity.
Conclusions:
- Student populations can serve as a key group for leprosy surveillance.
- Targeted screening in specific linguistic and gender groups may enhance early detection efforts.
- The low rate of lepromatous and high rate of early-stage tuberculoid leprosy suggest successful interventions or a favorable disease profile in this cohort.
