“…Approximately half of scorpion stings occur in summer, with the most recorded cases in August (18.7%) followed by July (17.6%), corresponding to the hottest and driest months of the year. This is in accordance with studies performed in other regions affected by scorpionism [5,13,14]. All municipalities of the province are affected by scorpionism at different levels, and most cases have been recorded in rural areas.…”

OBJECTIVESThe aims of this study were to highlight some epidemiological aspects of scorpion envenomations, to analyse and interpret the available data for Biskra province, Algeria, and to develop a forecasting model for scorpion sting cases in Biskra province, which records the highest number of scorpion stings in Algeria.METHODSIn addition to analysing the epidemiological profile of scorpion stings that occurred throughout the year 2013, we used the Box-Jenkins approach to fit a seasonal autoregressive integrated moving average (SARIMA) model to the monthly recorded scorpion sting cases in Biskra from 2000 to 2012.RESULTSThe epidemiological analysis revealed that scorpion stings were reported continuously throughout the year, with peaks in the summer months. The most affected age group was 15 to 49 years old, with a male predominance. The most prone human body areas were the upper and lower limbs. The majority of cases (95.9%) were classified as mild envenomations. The time series analysis showed that a (5,1,0)×(0,1,1)12 SARIMA model offered the best fit to the scorpion sting surveillance data. This model was used to predict scorpion sting cases for the year 2013, and the fitted data showed considerable agreement with the actual data.CONCLUSIONSSARIMA models are useful for monitoring scorpion sting cases, and provide an estimate of the variability to be expected in future scorpion sting cases. This knowledge is helpful in predicting whether an unusual situation is developing or not, and could therefore assist decision-makers in strengthening the province’s prevention and control measures and in initiating rapid response measures.

“…The epidemiological analysis showed that males were stung much more often than females (62% vs. 38%); a similar trend has also been observed on the national level (57% vs. 43%) [15] and in findings reported from other countries [14,16]. The age group of 15 to 49 years old was the most commonly affected, including 66% of stung people.…”

“…Although scorpion stings can be prevented and should be considered a priority for research to create a successful health program, this is the first study conducted in the endemic regions of Morelos that associates the increase of scorpion sting cases with changes in temperature and precipitation. Previous studies have found an association among scorpion sting incidence, climatic, and geographic characteristics (Camacho‐Ramírez et al ., ; Gómez and Otero, ; Charrab et al ., ; Secretaría de Salud, ). The results of this study are similar with those obtained in the State of Colima, Mexico (Chowell et al ., , ), where changes in the minimum temperature explains the higher percentage of variability in scorpion sting incidence.…”

Scorpion stings are a major public health concern representing a frequent cause of intoxication in many countries. The present study aims to examine the impact of climate variability in different climatic regions of the state of Morelos in Mexico on the incidence of scorpion stings. An ecological study was conducted using a retrospective time‐series analysis. Weekly reported scorpion sting cases from the Unique System of Information for Epidemiological Surveillance (SUIVE) and daily temperature and precipitation from the National Meteorological Service were obtained from 1999 to 2007. The geographical region of study was divided according three climatic conditions into Hot region (HR), Warm region (WR) and Cold region (CR). Generalized Linear Models were used to estimate the percent change [95% confidence intervals (CI)] of scorpion sting cases associated to an increase of 1 °C of temperature and 1 cm of precipitation in each climatic region. During the period of study there were 281 076 scorpion sting cases reported in the State of Morelos, Mexico. Positive correlations among temperature and scorpion sting cases were found (R = 0.59 and 0.70 in the HR and WR, respectively). Regions with the hottest temperatures had the greatest effect, showing a 9.8% (CI 95%: 8.30–11.30) increase in scorpion sting cases per 1 °C increased in temperature. Increase in minimum and maximum temperatures have a delayed effect on scorpion stings cases and these may vary by climatic region.

In Morocco, the Marrakech-Tensift-Al Haouz region is one of the 16 regions most affected by poisoning. The aim of this study was to determine the epidemiological profile of poisoning recorded in the study region. A retrospective study of poisoning cases, declared between 1981 and 2008 in the Morocco Poison Control and Pharmacovigilance Center, was conducted. During the study period, 8517 poisoning cases were collected. The average age of patients was 22 ± 15 years. The male/female sex ratio was 0.85. Food poisoning was the most reported in the region, with 26.6% of cases. Among the 2,779 patients for whom the outcome was known, 65 died, with lethality rate of 23.4‰. The maximum lethality rate was recorded among those poisoned by paraphenylenediamine (170.7‰).
