Objective: To analyze the ecological association between socioeconomic, occupational, and sanitation characteristics and scorpionism in Brazil. Methods: Ecological study with data on scorpion accidents reported in the Notifiable Diseases Information System (2007-2019). Negative binomial regression was used to estimate ratios of incidence rates (RTI) and confidence intervals (95%CI). Results: In the period, 1,079,333 scorpion accidents occurred, with accumulated incidence 41.5/100,000 in habitants. In the adjusted analysis, there was an association with the municipal percentage of: women (IRR=1.65 – 95%CI 1.18;2.30) and men (IRR=0.90 – 95%CI 0.88;0.91) in civil construction, women (IRR=1.21 – 95%CI 1.18;1.25) and men(IRR=0.73 – 95%CI 0.69;0.77) in domestic service, women (IRR=1.03 – 95%CI 1.02;1.04) and men (IRR=0.93 – 95%CI 0.92;0.93) in agriculture, households with garbage collection (IRR=0.99 – 95%CI 0.98;0.99) and garbage in surroundings(IRR=1.02 – 95%CI 1.01;1.02), expectation of years of study (IRR=0.88 – 95%CI 0.83;0.92), and unemployment rate (IRR=1.07 – 95%CI 1.05;1.09). Conclusion: Scorpionism was associated with precarious infrastructure/sanitation, job offer, education and female occupation.

Objetivo: Analisar associação ecológica entre características socioeconômicas, ocupacionais e de infraestrutura/saneamento com escorpionismo no Brasil. Métodos: Estudo ecológico, com dados dos acidentes escorpiônicos notificados no Sistema deInformação de Agravos de Notificação (2007-2019). Empregou-se regressão binomial negativa para estimar razões de taxas de incidência (RTI) e intervalos de confiança(IC95%). Resultados: No período, ocorreram 1.079.333 acidentes, com incidênciaacumulada de 41,5/100 mil habitantes. Na análise ajustada, houve associação com percentual municipal de mulheres (RTI=1,65 – IC95% 1,18;2,30) e homens (RTI=0,90 –IC95% 0,88;0,91) na construção civil, mulheres (RTI=1,21 – IC95% 1,18;1,25) e homens(RTI=0,73 – IC95% 0,69;0,77) no serviço doméstico, mulheres (RTI=1,03 – IC95% 1,02;1,04) e homens (RTI=0,93 – IC95% 0,92;0,93) na agropecuária, domicílios com lixo coletado (RTI=0,99 – IC95% 0,98;0,99) e lixo no entorno (RTI=1,02 – IC95% 1,01;1,02),2 expectativa de anos de estudo (RTI=0,88 – IC95% 0,83;0,92) e taxa de desocupação (RTI=1,07 – IC95% 1,05;1,09). Conclusão: O escorpionismo associou-se a precária infraestrutura/saneamento, oferta de emprego, educação e ocupação feminina.

Great part of lhe avaiable data about snakes reprodution refers to species coming from subtropical and temperate regions. In Brazil, the data is rather rare and can be found in various works where information is restricted. Results from studies developed with five viviparous snakes - Crotalus durissus cascavella (Wagler, 1824). Bothrops erythromelas(Amaral, 1923), B. leucurus (Wagler, 1824), Helicops leopardinus (Schlegel, 1873) and Thamnodynastes strigilis (Thiinberg, 1787) - which come from the Northeast of Brazil (Bahia) are described. Data about pregnancy and birth, number, sex ratio, length and weight of neonates is given and discussed.
