Epidemiologic trends of leprosy for the 21st century.

Major gaps still exist in the knowledge about leprosy, particularly with regard to how it spreads. Leprosy epidemiology remains complicated due to the specific characteristics of Mycobacterium leprae. To describe epidemiologic trends for the 21st century, the first part of this paper gives an overview of the epidemiology of leprosy, followed by past trends and the present situation of new-case detection as a proxy of the incidence.

An evaluation of the Sinan health information system as used by the Hansen's disease control programme, Pernambuco State, Brazil.

Background: Since the introduction of the national notifiable diseases information system (SINAN) in Pernambuco State, Brazil, in 1994, many problems have been encountered. The aim of this study was to evaluate the SINAN software, quality of data input, the transfer of the computerised data from the municipality to state levels, human resources and other factors associated with the health information system infrastructure (HIS).

Methods: A cross-sectional study was carried out in Pernambuco state, North-eastern Brazil, in 2005.

Role of dermatologists in leprosy elimination and post-elimination era.

Would it not have been better to have left out the word 'elimination' altogether in the question and do what WHO has done in its new strategic plan for 2006-2010, 'Global Strategy for further reducing the Leprosy Burden and Sustaining Leprosy Control Activities'? Why not use a title such as 'The Role of Dermatologists in reducing the Leprosy Burden and Sustainig Leprosy Control Activities'? Some elements of the 'foundation' of the elimination policy have been (and are still) very controversial, its definition and the unsubstantiated (up till now) claim that when reaching a prevalence rate of less than 1 per 10,000, the transmission of the infection would be interrupted and the incidence would therefore decline.

Health systems research training as a tool for more effective Hansen's disease control programmes in Brazil.

In Brazil, Hansen's disease (HD) is still a public health problem. Although much progress has been made in Hansen's disease control (HDC) at all levels of government over the past 20 years, efforts have been hampered by information gaps related to specific areas of the disease, exacerbated by an absence of appropriate evaluation instruments and routine systematic analysis. Health Systems Research (HSR) aims to collect the necessary data to provide the most relevant information to policy makers and health managers to take more informed decisions.

Impairments and Hansen's disease control in Rondônia state, Amazon region of Brazil.

This retrospective study of impairments in a decentralized and integrated, routine Hansen's disease (HD) programme was done on a cohort of all new patients detected in Rondônia state from 1996 to 1999. It shows that the dynamics of impairments during treatment in Rondônia are similar to what has been published in other recent studies from Africa and Asia. Data about impairments at detection and at release from treatment (cure), the prescription of steroids, and epidemiological information are provided.

A comparison of Rapid Village Survey and Leprosy Elimination Campaign, detection methods in two districts of East Java, Indonesia, 1997/1998 and 1999/2000.

A Rapid Village Survey (RVS) was planned to estimate the extent of the leprosy problem in two well documented endemic districts of East Java, Indonesia. Furthermore, the aim was to investigate the efficacy of the routine programme in detecting new and early cases, as well as the feasibility of RVS in detecting disabled people affected by leprosy in the community. A random sample survey (RVS: a simple method compared to a Population Sample) was used to determine the extent of the leprosy problem.
