Prevalence and risk factors for bovine tuberculosis in Minas Gerais State, Brazil

AbstractThe aim of this study was to evaluate the distribution of cases and the social determinants associated with death from human visceral leishmaniasis (HVL) and VL–HIV co-infection in Belo Horizonte, Minas Gerais state, Brazil, between 2006 and 2013. Descriptive statistics and analysis of associations were performed using chi-square of the raised variables, such as sex, age, skin colour and schooling of cases of HVL. During the study period, there were 866 cases of HVL with 111 deaths in Belo Horizonte. Morbidity and lethality rates (LR) of HVL in Belo Horizonte remained high over almost all the years evaluated, with an average incidence rate of 4.18 cases/100 000 inhabitants and a LR of 11.16%. With respect to skin colour, it was found that people characterised as black or mulatto had higher morbidity, followed by white. Regarding schooling, LR was more prevalent among individuals with lower education. One of the social risk factors was co-infection with HIV, which was present in many cases of HVL. Furthermore, it was found that older age and the male sex were also risk factors for death from HVL in Belo Horizonte.

An epidemiological survey was carried out in 3,344 people of an urban town in Lagamar, Minas Gerais, Brazil - during 1992-1993, to evaluate the main risk factors related to taeniasis and cysticercosis. A total number of 875 (78.9%) houses were visited and 1080 (32.3%) subjects were clinically examined. Poor sanitary conditions were positively associated with former history of taeniasis or seizures in households (p < 0.05). It was remarkable the positive relationship between taeniasis and seizures when households were questioned and subjects were clinically evaluated (p < 0.05). The relative risk of seizures was 2.3 between households and 1.7 for individuals clinically examined respectively. The breeding of swine nearby and the chronic carriers of taeniasis are determinant factors in the maintenance of the epidemiological link between taeniasis and cysticercosis in endemic areas.

Spatial And Temporal Analyses

ABSTRACT: The application of spatial and temporal analysis in epidemiology aims to understand the causes and consequences of spatial and temporal heterogeneity in studies of infectious diseases. Bovine tuberculosis (bTB) is a chronic and progressive infectious disease caused by Mycobacterium bovis and is an important zoonosis worldwide. The aim of this study was to conduct spatial and temporal analyses of a secondary database of bTB-positive cases registered by the Federal Inspection Service in two slaughterhouses from the West of Minas mesoregion of Minas Gerais state, Brazil, from 2008 to 2012 and to suggest its use in epidemiological surveillance. The culled cattle with bTB macroscopic lesions during post mortem inspection were considered positive in this study. The data used were the positive cases registered on the “Sistema de Informações Gerenciais do Serviço de Inspeção Federal” (SIG/SIF - Management Information System of the Federal Inspection Service) of the “Ministério da Agricultura, Pecuária e Abastecimento” (MAPA - Ministry of Agriculture, Livestock and Supplies), the number of animals slaughtered monthly and their municipalities of origin, per slaughterhouse. The prevalence (%) of cases per cattle slaughtered was calculated, and the relationship between these cases of bTB and cases of human tuberculosis (hTB) and the GDP per capita of the mesoregions comprising the municipalities surveyed was evaluated. The prevalence was 1,030 cases of bTB (0.28%). The lowest case numbers and prevalence rates were obtained in 2010, while the highest rates were observed in 2011. Slaughterhouse 1 showed stationarity, while Slaughterhouse 2 showed an increasing annual trend for data since October 2009. A statistical correlation between the numbers of cases of bovine and human TB (p=0.006, r=0.148) was observed. The prevalence for Slaughterhouses 1 and 2 were not correlated (p>0.05). The municipalities of origin demonstrated randomness in their spatial distribution. SIG/SIF-MAPA may be used for the analysis of spatial and temporal distribution to contribute to the monitoring of animal health services with information on the prevalence of culling for bTB in the West of Minas, South/Southwest of Minas, Campo das Vertentes and Zona da Mata mesoregions of Minas Gerais, Brazil.
