Prevalence of leprosy in slums in Bombay including a leprosy colony.

Transmission of leprosy which is related directly to the total quantum of infection in the community as a whole is decided by the existence of patients suffering from progressive and infectious forms of leprosy and their movement from place to place. This information is of great importance in cities like Bombay to identify the priority areas as targets towards which control efforts should be directed. In this presentation an attempt has been made to compare the leprosy survey figures from three different situations in the city. Selection is arbitrary, not made on statistical basis. The data of particular importance is from a leprosy colony located in North Bombay representing a hyperendemic situation and a normal slum adjacent to this colony, movement of population between these two colonies being free. Age specific prevalence rates of leprosy after examining more than 80% of population from these colonies are compared with data derived from normal slums situated elsewhere in the city. The figures reveal varying prevalence rates marked by an increasing trend in the prevalence figures, leprosy colony representing the largest pool of infection. These figures indicate that wider statistically planned investigations on similar lines in urban areas may provide epidemiological data useful for planning control measures on a more rational basis.

Leprosy detection through non-survey techniques.

Most practical and cheap techniques other than mass surveys to detect leprosy in urban slums are still not known. The population inhabiting a large somewhat isolated slum in North Bombay was exposed to intensive health education programmes over a period of two years. Leprosy cases reporting as a result of these measures as well as those detected by trained workers casually or through contact examination were registered at two weekly clinics conducted within the slum. A total of 184 patients out of whom 27 were smear +ve, were identifiable by these means. The population of the slum was found to be 18228. Total prevalence rate of leprosy after examining 14723 subjects in the colony was revealed to be 24 per 1000 (smear +ve cases: 2.2. per 1000) out of which a prevalence of 12.4 per 1000 (smear +ve cases: 1.8 per 1000) had actually come to our knowledge even before instituting mass surveys. The results of this study indicate that in comparable urban situation it should be possible to identify 54% of total leprosy cases by techniques other than surveys. More significantly a striking feature of this study is that 82% of cases of true public health significance namely smear +ve patients could be unearthed by these means.

Evaluation of standard Dharmendra lepromin.

Dharmendra lepromin standardized at Central JALMA Institute for Leprosy (CJIL) by bacterial counts was used by different observers in four different Centres to assess the early and late reactions. Patients taken into the study were from different ethnic groups in different regions of the country. Comparable skin reactions were found at the Bombay Leprosy Project (BLP), Bombay and at the CJIL, Agra wherein a large number of patients were taken in the study. Similarly, when a smaller number of patients were taken in the study at the Base Hospital (BH), Barrackpore, and at the Jawaharlal Institute of Postgraduate Medical Education and Research (JIPMER), Pondicherry, the skin reactions noted in patients at these Centres were again found to be statistically comparable.

Field follow-up of leprosy cases in an urban area.

To achieve effective case holding in SET programme "treatment reminder" through home visits by field personnel is of much importance as drug compliance of leprosy cases is known to be very poor in general. A field study was undertaken to followup (A) school detected 158 leprosy cases (B) patients residing within project area especially 350 infectious cases as well as those 329 patients taking treatment elsewhere (C) 28 infectious patients from outside control area. (A) 70% Children diagnosed as leprosy through earlier surveys were available. 14% were believed to be regular for treatment 78% patients did not go for treatment. From this untreated group 73% showed features ranging from marked improvement to total regression of lesions. (B) 22% smear positive leprosy cases registered for treatment who dropped out from treatment over a period of 5 years were followed up. 21% dropped out cases had left the control area and their whereabouts were not known. From a group of 329 patients living in the control area of the same project who were believed to be taking treatment elsewhere only 48% could be contacted. The rest of them could not be contacted for various reasons. (C) During home visits to 28 infectious leprosy cases coming from far away places 21% said that they were taking treatment elsewhere. The figures in this study indicate the need for planning priority oriented home visit programme according to local situations to maintain at least infectious cases under regular treatment in view of the multiplicity of drugs as per the recent recommendations from experts.

An evaluation of the contribution of the Swedish International Development Authority (SIDA) to leprosy control in India based on the implementation of multiple drug therapy (MDT) 1981-1993.

The Swedish International Development Authority (SIDA) first supported the National Leprosy Control Programme in India in 1978. In 1981/82 priority was given to the implementation of multiple drug therapy (MDT), starting in two high-endemic districts, and gradually extending to a total of 19 districts in the years by 1993. SIDA then decided to undertake a detailed evaluation of its 12-year contribution and this was carried out by an international team between November 1993 and April 1994. In terms of epidemiological and public health impact, the main results were impressive and clear-cut; 837,519 cases (old and newly arising) were successfully treated, with few complications and a low rate of relapse. The voluntary reporting rate had improved significantly. Data relating to new case detection, child and disability rates were, however, less clear and difficult to interpret. Deficiencies were also identified in the areas of health education, community participation, gender issues, disability prevention and management, rehabilitation, operational research and assessment of cost-effectiveness. These problems should not, however, detract from the contribution of SIDA, from 1981 onwards, in establishing the implementation of MDT in two 'pilot' districts at an early and important stage in the history of the MDT programme in India. SIDA also made significant contributions in other areas, namely pre-MDT 'screening' of registers in 45 endemic districts in 1990-1993, appointment of consultant leprologists at district level, group education activities, annual meetings of voluntary agencies and the development of a monitoring and information system, with computer facilities, at national level. This paper describes the design and methodology, main findings and conclusions of the evaluation, based on the final report and the appendices submitted to SIDA in Stockholm in April 1994.
