Epidemiological trends of leprosy in an urban leprosy centre of Delhi: a retrospective study of 16 years.
This study was done by collecting the retrospective data from 1994 to 2009 of patients attending the urban leprosy centre attached to the department of dermatology, STD & leprosy of PGIMER & Dr. R M L Hospital, New Delhi. The data was analysed according to age, sex, type of leprosy, leprosy reactions, deformities and relapse and compared with the national figures by comparison of proportions after taking the national data per 10,000 population. A total of 3659 patients attended our ULC (Urban Leprosy Centre) among which 2741 were male and 945 females (M:F-3:1). 669 patients (18.2%) were children. The data analysed show a gradual decline in new case detection rate with a marginal rise in 2005 and 2008. Percentage of MB cases was falling consistently till 2005 after which it showed an abrupt rise. The incidence of type 1 reaction varied from 21% in 1994 to 10% in 2009 in PB patients and from 6% in 1994 to 8% in 2009 in MB patients. The trend of type 2 reactions in MB patients showed a slow declining trend. MDT completion rate showed an impressive improvement from 56% in 1994 to 90% in 2009. The number of patients revisiting the ULC with features of relapse also showed a decrease in number. The pattern of visible deformities showed an almost constant trend similar to national figures. Improved MDT completion rate helps in reducing the disease transmission, severity, reactions and disabilities.
