Leprosy in low endemic areas of India: an appraisal and suggested measures for control.

Prevalence of leprosy in the low endemic areas of India is described based on the observations of patients attending an Urban Leprosy Centre in the Union Territory of Delhi from the neighbouring states. The rising incidence in these so-called low to moderate endemic places is closely linked to factors related to urbanisation, movement of people in search of employment, etc., which necessitate fresh surveys in these areas. A significant number of leprosy patients attending the Centre were irregular (37.7%) in therapy and many absconded after the initial visit (35.3%), the reasons for which are discussed. These figures are compared to that from similar low endemic areas and known high endemic parts of the country. Suitable modifications to the control programme in these areas are suggested under the purview of the National Leprosy Eradication Programme.
