Abstract
The implementation of multiple drug therapy (MDT) in the State of Orissa, India, started in early 1983 and was extended in a phased manner to nine out of the then total of 13 districts by 1993. As part of a programme to bring the remaining four districts under MDT, an intensive screening of the registers was carried out in early 1993. From a total of 28,855 cases registered in these districts, 26,113 (90.5%) were examined and 18,008 (69.9%) deleted. The deleted included patients who had died, emigrated, double (or occasionally treble) entries for the same patient and those in whom careful re-assessment suggested that the original diagnosis of leprosy had been wrong. In addition, however, 8,260 (45.8%) of the 18,008 cases deleted were considered to have been cured by dapsone monotherapy. This figure, from districts with a relatively poor development of services for leprosy control, prompted a retrospective examination of data from the other (more privileged) nine districts. This revealed that from a total of 264,000 patients screened, prior to the implementation of MDT from 1983 onwards, 75,590 (28.6%) were removed from the registers, and that of these, 63,562 (84.0%) were considered to have been cured by dapsone monotherapy. Thus from a total of 93,598 patients removed from registeres in this State since 1983, 71,822 (76.7%) have been assessed as cured by dapsone monotherapy. The significance of this finding and its apparently considerable contribution to the overall reduction in the prevalence of leprosy in Orissa, 1983-1993, is discussed.
