“…Clinical symptoms and mortality from scorpion stings are related to two main factors: the characteristics of the stung patient (such as age and health condition) and the characteristics of the scorpion (such as species and venom potency) [ 77 , 119 , 120 ]. Scorpionism by Hemiscorpius is an important public health issue in Iran, especially in urban areas of the southwest and south regions.…”

“…A positive significant correlation between the frequency of scorpion stings and the environment temperature as well as the sunshine duration was reported [ 73 ]. However, the correlation between stings and relative humidity as a climate factor was negative [ 77 ].…”

“…Contrarily, a few studies reported that the frequency of recorded scorpion stings in both genders was nearly similar and there was not any significant difference between male and female in all age groups [ 16 , 21 , 69 , 79 ]. Another observation was that women were more stung by scorpions in indoor places, whereas men were more at risk in the outdoors [ 77 ].…”

Scorpions are distributed throughout Iran and the genus Hemiscorpius is particularly important in this region. Hemiscorpius lepturus is the most significant species within the genus in the country. Since scorpionism provoked by Hemiscorpius comprises a medical emergency, the present study is focused on this important issue. In order to perform the present work, a review of the medical and health-related literature was carried out in several databases. The current findings indicate that six species of Hemiscorpius are found in 15 states of Iran, mainly in the south and southwest. Deaths caused by stings were reported only for two species. The morphological characteristics and geographical distribution of H. lepturus in Iran, its venom and the toxic compounds, epidemiologic data and clinical manifestations of envenomation as well as treatment for affected people are herein reviewed and described. H. lepturus venom toxicity differs from other Iranian scorpions regarding duration and severity. Scorpionism is an important public health problem in Iran, especially in southwest and south regions and in urban areas. It is more prevalent in children and young people. H. lepturus venom is primarily a cytotoxic agent and has hemolytic, nephrotoxic and to some extent hepatotoxic activity. The use of polyvalent antivenom to prevent scorpion sting symptoms is recommended. A well-planned health education program might be useful in preventing scorpionism.

“…But assessing associated residual plot (graph not shown) revealed that there was a seasonal trend in the data. Although ACF and PACF for residual suggest an AR 1 model for seasonal trend, but in the ARMA × (1, 1) (1, 1) 12 model, AR 1 and SAR 12 were not significant (P = 0.276 and 0.831, respectively). Based on the corresponding RMSE value, the ARMA × (1, 0) (1, 1) 12 had the best fit for the available data and was thus considered the optimal model (Table 4).…”

Background: Snakebite envenomation is a vital status necessitating immediate treatment following case detection. Many cases of snakebites are recorded every year due to the suitable climatic conditions for the existence and survival of snakes in south Iran. Methods: In the present retrospective cross-sectional study, 195 snake (Reptilia: Squamata: Viperidae; Echis carinatus sochureki) bite cases referred to 10 rural health centers, two health care stations and the Haji-Abad Central Hospital of Hormozgan University of Medical Sciences (HUMS) were surveyed during 2012-2016. Seasonal time series models were applied to fit a linear model to describe and predict the monthly trend of snakebite cases. Results: Among these patients, males (70%, 136) from rural areas (79.5%, 155) were mostly recorded. The mean (± SD) age of victims was 33 (± 17.0) years old and the most common age group was 20-29 years (32%). Most snakebites took place outdoors (80%), on hands and legs (97%), and among unemployed people and farmers (61.0%). Snakebites often happened between midnight and 6 am (32%); also 51% of them occurred during summer. Most (70%) patients had pain at the bite sites. The location of being bitten (indoors or outdoors) had a significant difference with patient's sex (χ 2 = 7.764, P = 0.021). Conclusions: Time series analysis proposed a mixed seasonal autoregressive moving average, ARMA × (1, 0) (1, 1) 12 as the best process for the monthly trend of snakebite and to predict the incidence of snakebites. Local residents should be more cautious on snakebites during warm seasons.

“…This method is, however, unable to distinguish between the promastigote and amastigote forms of the parasite. The detection of L. major kDNA in wild sandflies of this region points to the increasing clinical significance of ZCL in recent years, in addition to the non-infectious (Ebrahimi et al 2017) and other infectious diseases (Fakoorziba et al 2006;Farhadpour et al 2016;Neghab et al 2006) in southern parts of Iran. Despite attempts to look for the presence of Crithidia parasite both in human lesion smears and naturally caught sandflies near rodent burrows and domestic settlements, no trace of its kDNA was discernible.…”

Zoonotic cutaneous leishmaniosis (ZCL) is a crucial public health challenge in Iran. Sandflies feed on reservoir rodents' blood infected with parasite and transmit it to other hosts. This study was conducted to find out the composition and monthly activity of sandflies as well as to identify the protozoan pathogens (/) by polymerase chain reaction (PCR) in an emerging ZCL focus of Abarkooh, Yazd province, Iran, in 2016. A cross-sectional study was done in rural areas of Abarkooh. From April to November 2016, sticky traps were used indoor and outdoor to capture sandflies once every fortnight. Their composition and monthly activity were recorded. Following identification of sandflies and DNA extraction from them, PCR was used to identify their parasite and match it against samples taken from ZCL confirmed and suspected patients' lesions. After collection, a total of 2045 sandflies (779 indoor, 1266 outdoor) were identified to species level. Sandfly activity started early April in this area with two active peaks (one late May and the other late August) terminated about mid-November. Seven species and three species were identified. The most and the least abundant species were (40.1%) and (0.09%), respectively. Using PCR, only 6% (12:200) of sandflies were infected with parasite. No was detected in either sandflies or human lesions (176 specimen). Based on the highest abundance both indoor and outdoor of, this sandfly was considered the main vector of ZCL in this area. The capture of ,, and from rodent burrows showed these species were likely involved in pathogen transmission in reservoir rodents' burrows.
