Prevalence of leprosy in Agra District (U.P.) India from 2001 to 20031.
Leprosy prevalence has reportedly declined all over the world, but six countries, including India, are still endemic for the disease. India alone contributes about 60% to the world's leprosy case load, with the major share from its northern states. The present study done in Agra district was based on a randomly-selected sample of over 10% of the population, spread across 300 villages and 16 urban units of the district. A house-to-house survey was conducted from July 2001 to July 2003 in all the 26 selected panchayats (300 villages), all the 11 block headquarters which have an urban component, and 5 (out of 20) localities in Agra city. A population of 361,321 persons was examined for leprosy. A total of 592 leprosy cases [new and cases yet to complete a full course of multi-drug therapy (M.D.T.)] were found, giving a prevalence rate of 16.4/10,000 population. Although the overall prevalence was found to be similar in both rural and urban areas, there were pockets with high prevalence. More cases were detected in the eastern side of Agra (31.4/10,000 in Fatehabad and 28.5/10,000 in Bah Tahsils). Overall, the multibacillary (MB) leprosy rate was 22.3% and the child leprosy rate 8.4%. Of the 592 cases, 523 (88.3%) were new untreated cases, giving a new case detection rate of 14.5/10,000. The MB rate was 17% (89/523), and the child leprosy rate was 8.4% (44/523) among the new patients. The grade 2 deformity rate was found to be 4.8% (25/523) among these cases. The duration of disease among new cases was 32.3 months as compared to 48.1 months among prevalent (registered) cases (i.e., patients who had been diagnosed earlier and had yet to complete a full course of M.D.T.). The large number of undetected cases found in this survey suggests the need for continued intensive health education campaigns and case detection activities. This study highlights the fact that a large number of leprosy cases go undetected in the present integrated system which is mainly based on voluntary reporting of cases.
