Epidemiological aspects of American cutaneous leishmaniasis (ACL) in an endemic area of forest extractivist culture in western Brazilian Amazonia

The study sought to analyze clinical and epidemiological aspects of cutaneous leishmaniasis (CL) in Xapuri, Acre, Brazil. Data from 2008 to 2014 registered in the notification records of the disease of the Information System of the Complaints of Notification (SINAN), and the data of the Information Department of the Unified Health System (DATASUS) available from 2007 to 2013 were used and analyzed in the light of the statistics of the temporal series by the Prais-Winsten method and chi-squared test. A total of 906 cases were registered with 60.2% occurring in men and 39.7% in women. The groups from 0 to 4 years of age (48.0%) and from 5 to 19 years of age (23.3%) were the most affected. Regarding the clinical forms, 77.7% presented CL and 22.3% mucocutaneous leishmaniasis (MCL). Among the 896 cases with information on the diagnostic methods used, Montenegro’s skin test predominated (66.4%), with a positive result of 95.8% for CL and 99.3% for MCL. Treatment with N-methylglucamine antimony was performed in 99.4% of the cases, but discontinuously used in the majority of patients. This study presents information which may be used as a tool for the epidemiological surveillance and control of the disease in Xapuri, a region which depends essentially on forest resources and ecological tourism.
