Objective: To determine the knowledge, attitude and practice of healthcare workers in Kermanshah Province about Crimean-Congo hemorrhagic fever(CCHF).Methods: This study was conducted in 2014 on healthcare personnel in different job categories including physicians, nurses, midwives, laboratory staff and network health staff of Kermanshah Province by direct ***: A total of 367 respondents who had more than 5 years of experience in their jobs were interviewed. Among them 91% of physicians and nurses, 97% of midwives and health workers and 96% of laboratory staff stated that they had not been confronted with CCHF patients so far. Regarding knowledge, 76% of physicians, 78% of nurses, 77% of midwives and 58% of laboratory staff believed that the disease is remediable. Most of the interviewed participants stated that the disease pertains to people who are in close contact with domestic animals, but they did not consider their own occupations as one of the risk factors. More than 70% of the respondents believed that the disease may exist in the province or their work field. Generally, the knowledge about CCHF was inadequate, with nurses having the lowest level of ***: Knowledge of Kermanshah healthcare staff about CCHF was poor,especially nurses in a high risk job category. Therefore, it is necessary to conduct specific training programs for the disease identification, transmission, prevention, and treatment as well as the use of personal protection and safety devices.

Resistance status of main malaria vector, Liston (Diptera:Culicidae) to insecticides in a malaria Endemic Area,Southern Iran

引用

Asian Pacific Journal of Tropical Medicine 2019年第1期12卷 43-48页

作者： Madineh Abbasi Ahmad ali hanafi-bojd Mohammad Reza Yaghoobi-Ershadi Hassan Vatandoost Mohammad ali Oshaghi Teimour Hazratian Mohammad Mehdi Sedaghat Sajjad Fekri Reza Safari Abdol Rasoul Mojahedi Yousef Salari Department of Medical Entomology & Vector Control School of Public Health Tehran University of Medical Sciences Department of Environmental Chemical Pollutants and Pesticides Institute for Environmental Research Tehran University of Medical Sciences Department of Parasitology School of Medicine Tabriz University of Medical Sciences Department of Diseases Control Hormozgan University of Medical Sciences

Objective: To evaluate the susceptibility of Anopheles stephensi(An. stephensi) Liston, the main malaria vector in southern Iran, to WHO recommended insecticides. Methods: Larvae of An. stephensi were collected from three different larval habitats in both urban and rural area of Bandar Abbas city and one rural area in Rudan county southern Iran. WHO standard method was used for evaluation of adult and larval mosquito susceptibility. Bendiocarb, permethrin, lambda-cyhalothrin, deltamethrin as insecticide and temephos and chlorpyriphos as larvicide were used at the diagnostic dosages recommended by WHO. Results: Findings of this study showed all larval populations of An. stephensi were completely susceptible to temephos and candidate for resistance to chlorpyriphos. Adult mosquitoes in rural areas of Bandar Abbas city were resistant to pyrethroid and carbamate insecticides. Conclusion: Comparison of the results of this survey with previous studies indicates that the resistance to pyrethroids and carbamates in this malaria endemic region is increasing. Wide use of pesticides in agriculture is certainly effective in increasing resistance. The inter-sectoral coordination and collaboration in health and agriculture seem to be necessary to manage insecticide resistance in malaria vectors.
