[An increase in Hansen's disease in northeastern Brazil].
The epidemiological aspects of hanseniasis in Recife from 1960 to 1985 were studied. Clinical-epidemiological records of 3,923 leprosy patients reported to the Secretaria de Saúde do Estado de Pernambuco were reviewed. The cruce as well as the age, sex and type-specific detection rates were calculated. The way the cases were detected and the time elapsed between the appearance of the first symptoms and the disease was analysed. The analysis of the time trend during the observation period showed an increase in the detection rate with time, rising from 5.5 per 100,000 inhabitants in 1960 to 36.1 per 100,000 inhabitants in 1985. The higher frequency of the tuberculoid type of leprosy and the high percentage of patients under 15 might refleet the expansion of the disease in Recife. The decline and the stabilization in the time elapsed between the appearance of the disease and its detection, from 1979 onwards, indicates a more prompt detection and, as a consequence of that, that the rate of detection is approaching the incidence rate. From 1970 to 1985 the most common means of detecting cases of Hanseniasis was through dermatological consultation followed by disease notification. Only 14.2% of the cases were discovered through the surveillance of contacts. The analysis of the epidemiological and operational indicators suggest that the increase in the detection rate over the period from 1960 to 1985 was due both to expansion of the disease and improvement in control measures. The prevalence rate of Hanseniasis in Recife in December 1984 was 2.04 per 100,000 inhabitants; according to the WHO criteria Recife may be considered an area of high endemicity.
