“…A study in Egypt (5) found that the detection of new cases of leprosy creates a better picture of disease endemicity, in comparison to prevalence, because it is not affected by the changing definitions for endemicity standards or duration of treatment. This claim may be justified by a global frequency study (6) when it suggests that the detection of new cases increases the prevalence of the disease when evaluated for a short time. In other more immediate terms, prevalence is valuable for the healthcare system but not for the community, which represents an operational variation rather than an epidemiological variation.…”

RESUMO Objetivo Caracterizar a tendência, segundo indicadores epidemiológicos e operacionais, de endemia da hanseníase no Estado da Paraíba no período de 2001-2011, com projeções para os anos de 2012-2014. Métodos Estudo epidemiológico de série temporal, retrospectivo e documental, realizado com 10.476 casos notificados de hanseníase, diagnosticados entre 2001-2011, nos 223 municípios do Estado paraibano. Utilizou-se para composição e análise dos resultados dois indicadores epidemiológicos e um indicador operacional além de software estatístico. Resultados Para o coeficiente de detecção anual de casos novos, verificou-se inclinação ascendente entre os anos de 2001 a 2005, com tendência de queda a partir de 2006. Quanto à incapacidade física, visualizou-se variação cíclica, com tendência à inclinação descendente, com classificação considerada de média efetividade. Conclusão Os resultados apontaram continuidade da endemia no Estado, existindo a necessidade de avaliações mais curtas voltadas aos programas e estratégias em saúde utilizadas no combate à hanseníase.

Leprosy is an infectious disease caused by Mycobacterium leprae infection. The incubation period after the primary infection can be as long as decades. This bacterium has a tropism for macrophages and Schwann cells and as result neuropathies are frequent. The state of Rio Grande do Norte in northeastern Brazil has areas of low and high endemicity for leprosy. The aim of this study was to analyze a leprosy time series from Rio Grande do Norte, from 2005 to 2014, based on data provided by the Notifiable Diseases Information System from the State Secretariat of Health. This was a quantitative, descriptive and analytical study. We considered variables such as sex, age, clinical form, operational classification and disability grade at diagnosis. There were 3,426 cases of leprosy reported of which 1,781 were females (52%). Of those patients, 29% presented disability at diagnosis. The high level of disability in patients along with the lack of information regarding disability levels indicates the need for more effective measures, with early diagnosis to decrease morbidity as leprosy still remains as a serious public health problem.

“…Several factors can be attributed to the permanence of the endemic, though, questions directed to transmission mechanisms, intracellular reproduction metabolism and immune response to human infection are mentioned as important means of investigation, for the formulation of more effective interventions in public health [5].…”

“…Changes in leprosy magnitude in endemic areas, probably, are only apparent after many years of work, that's why it's so important to monitor its progress [5]. However, improvements in health information systems are needed to avoid the weaknesses in these records that limit the achievement of other studies.…”

“…Elected aspects as well as contributing to the transmission chain maintenance are the long incubation period of the bacillus (from five to seven years), the chronicity of the clinical manifestations, the cases of hidden prevalence, the operational difficulty of health services, the ignorance by the population in relation to clinical manifestations and prejudice [4][5].…”
