“…This occurs because leptospirosis is associated with urbanization, which occurs in a disorganized manner, mainly on the margins of cities [24]. As a consequence, low-income population agglomerations occur without sanitation policies, necessary to reduce transmission sources and reduce residents' exposure to streams and sewage [25,26].…”

Objective: This study proposes an epidemiological analysis and distribution of human cases of leptospirosis reported in the State of Ceará, from 2013 to 2019. Methods: Descriptive study, with data on leptospirosis accidents reported in the Notifiable Diseases Information System between 2013 and 2019. Results: 344 cases and 24 deaths were reported, with emphasis on the second two months (41%), corresponding to an average annual incidence of 0.54/105 inhabitants and a fatality rate equal to 2.2% per year, directly related to rainfall rates. Of those affected by the disease, 72% were aged 20 to 59, 76% were men, 88% considered themselves black, 39% were residents of urban areas and 59% did not report their education; 87% were diagnosed using clinical-laboratory criteria and 76% were cured. Conclusion: There was an increase in reports of leptospirosis associated with rainfall, mainly affecting the economically active population, most of whom live on the social margins.

“…Likewise, though the prevalence for serovar Copenhageni was relatively low in our study (8.69% of all reactives), the fact that it is circulating in the herds is worthy of note. This serovar has synanthropic rodents as its most important maintenance host (Zacarias et al, 2008), and is one of the most important causative agents of leptospirosis in humans (Silva et al, 2015).…”

Leptospirosis is a globally occurring zoonosis. The disease is often asymptomatic in sheep, but it is a major cause of reproductive losses. In Rio Grande do Sul state, commercial sheep herds total over 2,600,000 animals. In this light, our study aims to identify seroprevalence of anti-Leptospira antibodies in sheep in a slaughterhouse with state inspection level. Blood samples were taken at the time of bleeding at the slaughter line. Eighty-one serum samples were submitted to the Microscopic Agglutination Test (MAT), using a panel of 12 serovars. A total of 23 (28.39%) were reagents for at least one serovar. According to the most prevalent serovars (Autumnalis, Hardjo and Bratislava), grazing alongside cattle and the presence of rodents on the farm, may be influencing the transmission of the agent to the sheep. Although the prevalence was similar to the national average (26%), it is lower than that most recently described for the region (34.26%), which may indicate advances in technification and the elaboration of prevention policies.

“…Assim, a conscientização de empregados e empregadores quanto à importância do uso de EPI, pode vir a amenizar a facilidade de contato com a bactéria no Rio Grande do Sul, propiciada por longas horas de trabalho em lavouras e condições ambientais ideais para multiplicação das bactérias. Silva et al (2015) práticas sanitárias precárias são amplamente observadas em propriedades rurais do Rio Grande do Sul, tais como lixo e acúmulo de lixo orgânico, falta de saneamento, falha no acondicionamento de alimentos e a qualidade da água negligenciada, promovendo a proliferação de ratos e animais silvestres de vida livre, facilitando a transmissão do agente etiológico para um hospedeiro suscetível.…”

A leptospirose é uma zoonose de distribuição mundial cuja transmissão às espécies suscetíveis ocorre pelo contato direto ou indireto com indivíduos infectados. A moléstia é causada por bactérias do gênero Leptospira, acomete tanto humanos quanto animais. No meio rural, o risco dos humanos em adquirir a doença é maior do que para os moradores do meio urbano, principalmente pelo contato com animais domésticos, sinantrópicos e silvestres. Nesse contexto, este trabalho objetivou revisar os principais estudos epidemiológicos sobre a leptospirose na área rural do estado do Rio Grande do Sul (RS) nos últimos vinte e cinco anos, inferindo sobre a influência das atividades agropecuárias nos casos da doença em humanos. Evidencia-se que as populações rurais no RS, principalmente as localizadas na região sul e central estão mais expostas e possuem maiores chances de contrair a leptospirose, quando comparadas com a zona urbana. No RS, as atividades que envolvem longos períodos de trabalho em contato com a água e a indisponibilidade, na maioria das vezes, de equipamentos de proteção individual (EPI), aumentam o risco para a contaminação com o agente. Entre os animais domésticos, destacam-se os caninos e bovinos como importantes transmissores da enfermidade para os humanos no meio rural. Além disso, falhas no saneamento e coleta de lixo favorecem a presença de roedores nas propriedades, elevando o risco para a ocorrência da doença. Assim, medidas como a reeducação, a informação sobre os principais fatores de riscos da doença e o uso de EPI podem ser utilizadas para prevenir casos graves de leptospirose no meio rural do RS.
