Detection of previously undetected leprosy cases in Firozabad District (U.P.), India during 2006-2009: a short communication.

OBJECTIVES This study was initiated to assess the extent of undetected (new) leprosy cases in Firozabad District of U.P. METHODS A sample survey of more than 980,000 people was undertaken in nine blocks of the district during October 2006 to March 2009, using a household questionnaire and a cross section survey. RESULTS A total of 774 previously undetected cases were detected (7.57 NCDR/10,000 population) over the 2.5 year period of the survey. The characteristics of previously undetected cases are described by age, sex, classification, urban/rural residence and disability. CONCLUSION There are many undetected leprosy patients in the community. Active surveys can help in detecting previously undetected cases. The current programme is based on information, education and communication (IEC) to encourage case reporting. IEC activities should be designed in such a way that people can suspect leprosy and are self-motivated to know about free treatment, its availability, and effectiveness.
