    Abstract:
    A cross-sectional study was carried out at Naihati municipal area in West Bengal to study the prevalence and some epidemiological factors in transmission of leprosy. Side by side, the validity of WHO operational classification was also tested by using slit skin smear examination as gold standard. A group of trained paramedical workers, supervised by epidemiologist conducted house to house survey work. Experienced dermatologist and neurologist examined suspected cases. Overall prevalence of leprosy were 9.9 per 10000, of which 53% were new cases. Epidemiologically manual workers, living in slums and unhygienic surroundings had significantly higher risk of developing leprosy. Sensitivity and specificity of WHO operational classification (> 5 skin lesion= MB) was found to be quite high (sensitivity 85.9% and specificity 83.3%) in this study. However addition of > 2 nerve lesions to this criteria increase sensitivity to 90.1% without much affecting the specificity (79.8%).
