“…It is noteworthy that in Brasiléia and Sena Madureira, most of the 970 570 hectares of the Chico Mendes reserve is found. This reserve is intended for self-sustainable exploitation and conservation of exhaustible natural resources by resident populations, who are found to be the most affected by ACL in the state [20, 21]. …”

Spatial and temporal distribution of American cutaneous leishmaniasis in Acre state, Brazil

2017

BackgroundAcre has reported the highest incidence of American cutaneous leishmaniasis (ACL) in Brazil in recent years. The present study seeks to identify high and low risk agglomerations of ACL in space and space-time during the period from 2007 to 2013 in Acre, and also to characterize the occurrence of the disease in time and according to sociodemographic variables.MethodsThis is an ecological study, the study population of which consisted of autochthonous ACL cases notified in the municipalities of Acre by an epidemiological surveillance system. Scan statistics of SaTScan™ software were used to identify spatial and space-time clusters. In addition, the cases were characterized by sex, age, home situation (in a rural or urban area), and temporal tendency.ResultsAcre reported an incidence rate of 12.4 cases per 10 000 inhabitant-years in the study period, with the rates varied greatly (standard deviation of 21.8) among their 22 municipalities. One agglomeration of high risk and three of low risk were detected in space and space-time. Four of the five micro-regions of Acre presented a stationary temporal tendency. The profile of transmission varied according to the micro-region. Generally speaking, the disease occurred more often among young people, those of male gender, and those living in rural areas.ConclusionsAcre has stood out within the Brazilian national context due to its high rates of ACL incidence in the central region of the Acre Valley. The high rates in the micro-region of Brasiléia are related to the disease’s intra/peridomiciliary occurrence, and it would seem that the municipality of Sena Madureira is approaching a transmission pattern similar to that of Brasiléia. In other micro-regions, the profile of the disease’s transmission is mainly related to the forest/sylvatic cycle of ACL.Electronic supplementary materialThe online version of this article (doi:10.1186/s40249-017-0311-5) contains supplementary material, which is available to authorized users.

“…The State of Acre has stood out in recent years within this scenario, especially by reason of such municipalities of the micro-region of Brasiléia as Xapuri 10 , 11 and Assis Brasil 12 , indicated as one of the main foci of the transmission of the disease.…”

“…This latter fact occurs frequently in the State as well as in rural areas of Amazonia, where populations acquiesce in the lack of treatment because of the difficulty of their travelling to the health center 11 , 28 particularly in rainy periods seeing that the access roads then become impassable and thus isolate them from the health centers.…”

“…Although the cutaneous clinical form is the most prevalent in Acre and also in the municipality of Xapuri, Natal and Silva 11 had already observed that in some regions of the state the mucocutaneous form was expanding. In fact, our finding 8 years after the period they studied corroborates the observations of these authors, suggesting further studies to clarify the reasons that are leading people to acquire this clinical form.…”

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.

“…9,26,27 Based on the Sistema de Informação de Agravos de Notificação (SINAN) database 28 The epidemiological profile of the studied group was as follows: men (86%) with a mean age of 52 years, living in a rural area, with a history of CL for a mean of 18 years, with no treatment or only incompletely treated, and with a mean of 5.4 years of nasal symptoms. This profile is similar to that of Guerra's 9 study in Manaus on 47 patients with ML; little difference in mean age (47 years) and in duration of nasal lesion (8.3 years) was observed.…”
