This study aimed to carry out a malaria situation analysis, species composition and susceptibility levels of the main malaria vector, Anopheles stephensi, to different insecticides in Bashagard. A longitudinal survey was conducted in 2 randomly selected villages in Bashagard. Malaria vectors were sampled by dipping method for the larvae and hand catch, night-biting catch, total catch, and shelter pit collection for the adults. Standard WHO susceptibility tests were used for a variety of insecticides on F1 progeny of An. stephensi reared from wild-caught females. In total, 693 adult anopheline mosquitoes and 839 third and fourth-instar larvae were collected and identified. They comprised 7 species; the most abundant adult and larvae anopheline mosquito was An. dthali (40.7% and 30.5% respectively). An. culicifacies (24.2%) and An. stephensi (16.7%) were the next most common species for adult mosquitoes. An. stephensi was fully susceptible to malathion and pyrethroid insecticides but resistant to DDT and tolerant to dieldrin.

Scorpion sting is a public health problem in south and southwestern parts of Iran, with about 36,000 cases recorded annually. This study aimed to find the spatial distribution of scorpions and their stings in Bandar Abbas County. Monthly scorpion sting cases at the village level were obtained and used for mapping. Scorpions were collected from 14 collection sites using a UV lamp at night and searching under stones during the day time. During the study period, a total of 3,971 cases of scorpion sting were recorded, most of them were found in mountainous areas and affected individuals aged 25-44 yrs. In total, 18 scorpion species belonging to 10 genera were collected and identified. The peak of scorpion sting cases occurred from July to September. The northern part of the mountainous areas had a richer species composition. Hemiscorpius persicus and Hemiscorpius gaillardi were collected for the first time in the area. There were 22 scorpion species in the area across studies; among them, 10 were most dangerous. Hemiscorpius genus is the main etiologic agent in Bandar Abbas County. Mapping dangerous species allows the health system to provide relevant anti-scorpion venom serum accordingly and more cost-effectively.

Background: Every year, thousands of cases and many deaths from scorpion sting are reported in tropical areas of South and Southwestern parts of Iran. The aim of this study was to identify the fauna and dangerous species of scorpions in Roudan County, southern Iran. Methods: This descriptive study was conducted in 10 stations in Hormozgan Province. Scorpion sampling was done randomly by searching for their shelter and digging out their nests during day, and with the use of UV light during night from February 2013 to October 2014. Data of scorpion stings were obtained from health center of Hormozgan Province during 2014–2016. Results: Overall, 155 scorpions were collected on a set of eight species belonging to Buthidae and Hemiscorpiidae fam-ilies. These species were identified as Mesobuthus persicus, Mesobuthus phillipsi, Hottentotta schach, Odontobuthus doriae, Compsobuthus persicus, Orthochirus farzanpayi, Androctonus crassicauda and Hemiscorpius acanthocercus. One thousand and twenty-seven cases of scorpion sting were recorded during 2014–2016 with a peak period in summer. Most of cases were <44yr old. Five out of six medically important scorpions in Iran were actively identified in the study area. Conclusion: Results of this study would greatly help to identify risk factors of scorpion sting in high-risk areas for planning, management and treatment of patients with scorpion sting in these areas.

IntroductionPeople in tropical and semi-tropical areas are in danger of scorpion sting, and this can be a serious problem for them. Mortality due to scorpion sting in the tropical and semi-tropical areas of Iran is about 75%, and this makes scorpion sting in these areas a serious medical problem. Because of this problem, our aim was to assess the epidemiological aspects of scorpion sting in Bandar Abbas, Iran, during 2009–2011.MethodsIn this cross-sectional retrospective study, epidemiologic data of 698 scorpion sting cases, who were referred to the Shahid Mohamadi Hospital of Bandar Abbas in Hormozgan Province collected from 2009 until 2011. The data included demographic and individual information, such as age, gender, geographic location, bite site, when the incident occurred, and anti-venom consumption. The required data were extracted from the patients’ recorded information in the Hospital, and we recorded data in a special checklist and imported the data into the computer for statistical analysis using of SPSS software, version 21.0. Descriptive statistics, including mean, standard deviation, frequency, and percentage, were used for data analysis.ResultsTwo hundred and sixty-one (37.4%) of the cases were urban and 437(62.6%) were rural. Males comprised 50.1% of the cases, and women comprised 49.9% (p >0.05). Twenty-five point two percent of scorpion sting cases occurred among people in the 21 to 30 age group, and there were very few cases among people in the 51 to 60 age range (p<0.05). Most of cases were recorded in April and October, and the fewest cases were recorded in July and January (p<0.05); also 32.2% of scorpion sting cases occurred after midnight and in the early morning hours.ConclusionOur survey showed that there was a high incidence of scorpion stings in rural areas, among 21–30 age group, among housekeepers, and among students. These results indicate the need for public education programs and better sanitation services in the rural areas around Bandar Abbas city. Prospective studies can help to health and medicine organization for prevention and treatment of scorpion sting.
