“…Organization for Animal Health (OIE) as the world's most widespread zoonosis (BRASIL, 2008). In the Brazilian Northeast, between 2000 and 2015, Pernambuco was the state with the highest morbidity (41.10%) and mortality (10.83%) of humans due to leptospirosis (SANTOS et al, 2018). In Brazil, leptospirosis is a reportable disease under epidemiological surveillance in both humans and animals.…”

“…Classified as a bacterial anthropozoonosis that affects domestic, wild, and synanthropic animals, leptospirosis is caused by pathogenic species of the genus Leptospira (BATISTA et al, 2016), with many serogroups identified, each of them having its preferred hosts (SANTOS et al, 2018). Some authors, such as Pinna et al (2008), consider equids as the main reservoirs for the Australis serogroup.…”

Brazil is the eighth largest exporter of equidae meat in the world. Most donkey meat is obtained from discarded animals, raising concerns about their health status, particularly regarding zoonotic infections such as leptospirosis. Thus, this study aimed to determine the frequency of anti-Leptospira sp. antibodies in Northeastern donkeys at two properties specializing in producing donkeys for slaughter and export to the Chinese market, in the municipalities of Parnamirim (A) and Araripina (B), both located in the mesoregion of the Sertão of Pernambuco, Northeastern Brazil. The serum of 349 donkeys was collected, including 147 males and 202 females, aged 3 to 12 years. All animals were subjected to the Microscopic Agglutination Test (MAT) using a cut-off point of 1:50. A total of 19.8% seropositive animals were obtained. The Icterohaemorrhagiae serogroup was the most found in this study (40.6%), followed by Australis (27.5%), Autumnalis (8.7%), Sejroe (8.7%), Pomona (8.7%), Celledoni (2.9%), and Tarassovi (2.9%). A higher overall rate of seropositivity was found in donkeys from property B (2.2.4%) in the municipality of Araripina. In the association analysis, it was observed that animals less than 9 years of age were more likely to be seropositive, this may be due to the acquisition of resistance to Leptospira sp. as age advances. A significant number of donkeys seropositive for Leptospira sp. was found, thus, breeding these animals for slaughter and export requires implementing prophylactic measures.

“…Several studies based on future climate projections have shown a significant increase in temperature and a drastic reduction in rainfall, followed by prolonged periods of drought and severe droughts and, finally, a trend towards aridity in the region causing desertification (Marengo et al 2017). The northeastern population is vulnerable to these climatic extremes, which often cause deaths, environmental damage, and socioeconomic impacts, and still affect the population with water‐borne diseases, after their occurrences (Monteiro, 1976; Cairncross and Feachem, 2018; Santos et al, 2018).…”

The objective of this study was to evaluate the annual standardized precipitation index (SPI) obtained from the DrinC software based on multivariate analysis in the identification of rainfall and drought extremes in the State of Alagoas and its relationship with El Niño-Southern Oscillation. Monthly rainfall data from 1960 to 2016 from National Water Agency were analysed. Annual SPI (SPI-12) has been designed for comparison with ENSO phases via Oceanic Niño Index for 3.4 region and in identifying climate extremes in the State of Alagoas. The principal component analysis and cluster analysis techniques were applied to the rainfall series of SPI-12. Extreme events were identified in both rainy and drought periods according to SPI-12, and were associated with the ENSO phases (El Niño, La Niña, and Neutral). The first four principal components explained 46.68% of the variance. Our findings are crucial for agriculture and civil defence since northeastern Brazil has several areas of risk and social vulnerability.

“…These are further classified by serology into more than 300 different serovars of which more 250 are known to infect humans (2). Leptospirosis is strongly associated with environmental factors including heavy rainfall, flooding, population growth, poor sanitation and hygiene and disasters (3,4).…”

Leptospirosis is a neglected infectious disease that affects humans and animals with a higher incidence in the tropics and subtropics. In that context, the aim of this study was to describe the temporal distribution of the epidemiology and sociodemographic factors of human leptospirosis in Brazil. The analysis conducted in this study was based to age, gender, area, schooling, region and skin colour reported by Ministry of Health from National Disease Notification System (SINAN) and National Survey of Household Samples (PNAD) database of Brazil, during the period 2007 to 2014. A total of 22,889 cases were reported, the majority of which were registered in male and urban area, more than 70% and 80%, respectively. The greatest number of cases occur in patients with age group between 20-39 years. However, there was a significant increase in children between 0 and 9 (p = 2.8×10-7), 10 e 14 (p = 0.015) e 70 e 79 (p = 0.021) years old. The North region highlighted in relation to the other regions of the country, with a significant increase (p = 2.4×10-11) in the number of cases. An epidemiological surveillance of leptospirosis is important in Brazil once the incidence of disease is increasing in children and the elderly. We also show are essential efforts between medical and governmental institutions to improve the quality of data. Understand the disease trends can be providing insights into the prevention and control of leptospirosis in Brazil and others development countries. Análise da incidência de leptospirose humana no Brasil RESUMO Leptospirose é uma doença infecciosa negligenciada, que afeta humanos e animais com maior incidência nos países tropicais e subtropicais. Nesse contexto, o objetivo deste estudo foi descrever a tendência de análise temporal e fatores sociodemográficos da leptospirose em humana no Brasil. A análise realizada neste estudo foi baseada na idade, sexo, área, escolaridade, região e cor da pele. Os dados obtidos do Sistema Nacional de Notificação de Doenças (SINAN) organizado pelo Ministério da Saúde e do banco de dados da Pesquisa Nacional de Amostras de Domicílios (PNAD) do Brasil, durante no período de 2007 a 2014. Foram relatados 22.889 casos, sendo a maioria destes registrados em homens e em área urbana, mais de 70% e mais de 80% dos casos, respectivamente. O maior número de casos ocorreu em pacientes com faixa etária entre 20 e 39 anos. No entanto, houve um aumento significativo em crianças com idade entre 0 e 9 (p = 2.8×10 7), 10 e 14 (p = 0.015) e 70 e 79 (p = 0.021) anos. A região Norte se destacou em relação as demais regiões do país, com um aumento significativo dos casos (p = 2.4×10-11). A vigilância epidemiológica da leptospirose no Brasil é importante, uma vez que a incidência da doença está aumentando em crianças e idosos. Também mostramos que são necessários esforços essenciais entre instituições médicas e governamentais para melhorar a qualidade dos dados. A análise de tendência temporal da doença pode fornecer informações sobre a prevenção e controle da leptospirose no Brasi...
