Background: This study was designed to find the best statistical approach to scorpion sting predictions. Study Design: A retrospective study. Methods: Multiple regression, seasonal autoregressive integrated moving average (SARIMA), neural network autoregressive (NNAR), and hybrid SARIMA-NNAR models were developed to predict monthly scorpion sting cases in El Oued province. The root mean square error (RMSE), mean absolute error (MAE), and mean absolute percentage error (MAPE) were used to quantitatively compare different models. Results: In general, 96909 scorpion stings were recorded in El Oued province from 2005-2020. The incidence rate experienced a gradual decrease until 2012 and since then slight fluctuations have been noted. Scorpion stings occurred throughout the year with peaks in September followed by July and August and troughs in December and January. Sting cases were not evenly distributed across demographic groups; the most affected age group was 15-49 years, and males were more likely to be stung. Of the reported deaths, more than half were in children 15 and younger. Scorpion’s activity was conditioned by climate factors, and temperature had the highest effect. The SARIMA(2,0,2)(1,1,1)12, NNAR(1,1,2)12, and SARIMA(2,0,2)(1,1,1)12-NNAR(1,1,2)12 were selected as the best-fitting models. The RMSE, MAE, and MAPE of the SARIMA and SARIMA-NNAR models were lower than those of the NNAR model in fitting and forecasting; however, the NNAR model could produce better predictive accuracy. Conclusion: The NNAR model is preferred for short-term monthly scorpion sting predictions. An in-depth understanding of the epidemiologic triad of scorpionism and the development of predictive models ought to establish enlightened, informed, better-targeted, and more effective policies.

Introduction Buthus species, including B paris, are classified as one of the most dangerous scorpion genera in Morocco, implicated in several cases of human death. Our objective is to characterize, for the first time, the toxicity and histopathologic and biochemical impacts of B paris venom. Methods We investigated the experimental pathophysiology of B paris venom by examining histologic changes in vital organs (heart, kidneys, liver, and lungs) and assessing biochemical enzymatic markers (alanine aminotransferase, aspartate aminotransferase, lactate dehydrogenase, creatine phosphokinase, urea, and creatinine) in mice injected subcutaneously with 2 doses of 400 and 450 mg·kg–1. Results Our results showed that the subcutaneous median lethal dose of B paris venom was around 0.52 mg·kg–1. Histologic findings revealed significant tissue damage in the previously mentioned vital organs, confirmed through biochemical analysis indicating impaired heart and liver functions. Additionally, an increase in urea, creatinine, and glucose levels occurred following B paris venom injection. Conclusion Our findings show that B paris venom exhibits a high level of experimental toxicity. These results highlight the potentially lethal nature of this venom and emphasize the potential medical importance of this species.
