BackgroundAlthough the detection rate is decreasing, the proportion of new cases with WHO grade 2 disability (G2D) is increasing, creating concern among policy makers and the Brazilian government. This study aimed to identify spatial clustering of leprosy and classify high-risk areas in a major leprosy cluster using the SatScan method.MethodsData were obtained including all leprosy cases diagnosed between January 2006 and December 2013. In addition to the clinical variable, information was also gathered regarding the G2D of the patient at diagnosis and after treatment. The Scan Spatial statistic test, developed by Kulldorff e Nagarwalla, was used to identify spatial clustering and to measure the local risk (Relative Risk—RR) of leprosy. Maps considering these risks and their confidence intervals were constructed.ResultsA total of 434 cases were identified, including 188 (43.31%) borderline leprosy and 101 (23.28%) lepromatous leprosy cases. There was a predominance of males, with ages ranging from 15 to 59 years, and 51 patients (11.75%) presented G2D. Two significant spatial clusters and three significant spatial-temporal clusters were also observed. The main spatial cluster (p = 0.000) contained 90 census tracts, a population of approximately 58,438 inhabitants, detection rate of 22.6 cases per 100,000 people and RR of approximately 3.41 (95%CI = 2.721–4.267). Regarding the spatial-temporal clusters, two clusters were observed, with RR ranging between 24.35 (95%CI = 11.133–52.984) and 15.24 (95%CI = 10.114–22.919).ConclusionThese findings could contribute to improvements in policies and programming, aiming for the eradication of leprosy in Brazil. The Spatial Scan statistic test was found to be an interesting resource for health managers and healthcare professionals to map the vulnerability of areas in terms of leprosy transmission risk and areas of underreporting.
Our results show that, because of its clinical and epidemiological profile, tuberculosis/HIV co-infection is still a major public health problem in the southwestern region of Maranhão. This situation calls for better coordination between tuberculosis and sexually transmitted disease/AIDS control programs, as well as a political commitment and greater involvement on the part of administrators and health care professionals in the planning of interventions and the functioning of health care facilities.
BackgroundIn Brazil, leprosy has been listed among the health priorities since 2006, in a plan known as the “Pact for life” (Pacto pela Vida). It is the sole country on the American continent that has not reached the global goal of disease elimination. Local health systems face many challenges to achieve this global goal. The study aimed to investigate how patients perceive the local health system's performance to eliminate leprosy and whether these perceptions differ in terms of the patients' income.Methodology/Principal FindingsA cross-sectional study was conducted in Londrina, State of Paraná, Brazil. Interviews were performed with the leprosy patients. The local health system was assessed through a structured and adapted tool, considering the domains judged as good quality of health care. The authors used univariate, bivariate and multivariate analyses. One hundred and nineteen patients were recruited for the study, 50.4% (60) of them were male, 54.0% (64) were between 42 and 65 years old and 66.3% (79) had finished elementary school. The results showed that patients used the Primary Health Care service near their place of residence but did not receive the leprosy diagnosis there. Important advances of this health system were verified for the elimination of leprosy, verifying protocols for good care delivery to the leprosy patients, but these services did not develop collective health actions and did not engage the patients' family members and community.Conclusions/SignificanceThe patients' difficulty was observed to have access to the diagnosis and treatment at health services near their homes. Leprosy care is provided at the specialized level, where the patients strongly bond with the teams. The care process is individual, with limited perspectives of integration among the health services for the purpose of case management and social mobilization of the community to the leprosy problem.
Introduction: Tuberculosis (TB) is the most common infectious disease in the world. We aimed to analyze the spatial risk of tuberculosis mortality and to verify associations in high-risk areas with social vulnerability. Methods: This was an ecological study. The scan statistic was used to detect areas at risk, and the Bivariate Moran Index was used to verify relationships between variables. Results: High-risk areas of tuberculosis mortality were statistically significantly associated with domain 2 of the Social Vulnerability Index (I=0.010; p=0.001). Conclusions: This study provides evidence regarding areas with high risk and that vulnerability is a determinant of TB mortality.
ABSTRACT:Objective: To investigate the knowledge regarding tuberculosis among relatives of patients with tuberculosis and the possible factors associated with this event and also to conduct comparative analyses between groups of relatives with or with few knowledge regarding tuberculosis, considering their attitudes in both groups. Methods: Cross-sectional study in which the sample was obtained through simple and randomized method. The data were collected by trained interviewers and validated tool. Logistic regression analyses were done using statistical software SPSS, version 22.0. Results: Among the 110 subjects recruited for the study, 85 (87.5%) were women, and the mean age was 49 years. Regarding common symptoms of tuberculosis, 102 relatives (90.9%) pointed the chronic cough; regarding the knowledge about tuberculosis transmission modes, 100 (90.9%) of them pointed symptomatic respiratory as the probable infection source. The relatives also reported other tuberculosis transmission models: sharing of clothes (n = 87; 79.1%) and household utensils (n = 66; 60%); sexual relations (n = 50; 50%). Illiterate relatives (adjusted OR = 4.39; 95%CI 1.11 -17.36), those who do not watch or watch little television (adjusted OR = 3.99; 95%CI 1.2 -13.26), and also those who do not have the Internet access (adjusted OR = 5.01; 95%CI 1.29 -19.38) were more likely to have low knowledge regarding tuberculosis. Regardless the group, with or without tuberculosis knowledge, the attitudes of both were satisfactory. Conclusion: There are evidences that social inequity is associated to the tuberculosis knowledge of patient relatives.
OBJECTIVE: To characterize deaths from pulmonary tuberculosis, according to sociodemographic and operational variables, in the city of São Luís, Brazil, and to describe their spatial distribution. METHODS: This was an exploratory ecological study based on secondary data from death certificates, obtained from the Brazilian Mortality Database, related to deaths from pulmonary tuberculosis. We included all deaths attributed to pulmonary tuberculosis that occurred in the urban area of São Luís between 2008 and 2012. We performed univariate and bivariate analyses of the sociodemographic and operational variables of the deaths investigated, as well as evaluating the spatial distribution of the events by kernel density estimation. RESULTS: During the study period, there were 193 deaths from pulmonary tuberculosis in São Luís. The median age of the affected individuals was 52 years. Of the 193 individuals who died, 142 (73.60%) were male, 133 (68.91%) were Mulatto, 102 (53.13%) were single, and 64 (33.16%) had completed middle school. There was a significant positive association between not having received medical care prior to death and an autopsy having been performed (p = 0.001). A thematic map by density of points showed that the spatial distribution of those deaths was heterogeneous and that the density was as high as 8.12 deaths/km2. CONCLUSIONS: The sociodemographic and operational characteristics of the deaths from pulmonary tuberculosis evaluated in this study, as well as the identification of priority areas for control and surveillance of the disease, could promote public health policies aimed at reducing health inequities, allowing the optimization of resources, as well as informing decisions regarding the selection of strategies and specific interventions targeting the most vulnerable populations.
