Uso combinado de marcadores sorológicos e análise espacial na vigilância epidemiológica da hanseníase

Abstract: Objetivo. Avaliar o uso combinado de marcadores sorológicos e análise espacial para ampliar a sensibilidade da vigilância epidemiológica da hanseníase. Método. Este estudo transversal foi realizado com vizinhos de casos de hanseníase e familiares e vizinhos de escolares com sorologia positiva anti-glicolipídeo fenólico I (PGL-I) em Diamantina, Minas Gerais, Brasil.

“…Considering the long incubation period of the bacillus and its clinical presentation, it is highly probable that the M. leprae infection occurred many years ago. This highlights an operational failure of the leprosy surveillance measures and a hidden prevalence of the disease 16 . This epidemiological profile is not unique to the population of Mozambique.…”

Despite the limitations of serologic testing and the specifics involving the immune system, there is consensus on the association between positive anti-PGL-I serology and a higher incidence of leprosy 18,16 . There is evidence that seropositive contacts are three times more likely to contract leprosy than seronegative contacts.…”
