  • Francisella tularensis human infections in a village of northwest Iran
  • 2021
  • Ingår i: BMC Infectious Diseases. - : Springer Science and Business Media LLC. - 1471-2334. ; 21:1
  • Tidskriftsartikel (refereegranskat)abstract
    • Background: Recent seroepidemiological studies have suggested that tularemia could be an endemic bacterial zoonosis in Iran.Methods: From January 2016 to June 2018, disease cases characterized by fever, cervical lymphadenopathy and ocular involvement were reported in Youzband Village of Kaleybar County, in the East Azerbaijan Province, northwestern Iran. Diagnostic tests included Francisella tularensis serology (including tube agglutination test and ELISA), PCR, and culture.Results: Among 11 examined case-patients, the tularemia tube agglutination test was positive in ten and borderline in one. PCR detected the F. tularensis ISFtu2 elements and fopA gene in one rodent and a spring water sample from the same geographic area.Conclusions: Based on the clinical manifestations of the disease suggesting an oropharyngeal form of tularemia, serology results in case patients, and F. tularensis detection in the local fauna and aquatic environment, the water supply of the village was the likely source of the tularemia outbreak. Intervention such as dredging and chlorination of the main water storage tank of the village and training of villagers and health care workers in preventive measures and treatment of the illness helped control the infection.

  • HIV prevalence and risk behaviours among people who inject drugs in Iran: the 2010 National Surveillance Survey
  • 2013
  • Ingår i: Sexually Transmitted Infections. - : BMJ. - 1368-4973 .- 1472-3263. ; 89, s. 29-32

    • Objectives To assess the prevalence of HIV and related risk behaviours among people who inject drugs (PWID) in Iran. Methods We conducted a national cross-sectional bio-behavioural surveillance survey between March and July 2010, interviewing male PWID from a geographically dispersed sample through a facility-based sampling method. Results We recruited 2480, and tested 2290 PWID. The overall prevalence of HIV was 15.2% (95% CI 9.7% to 23.1%). Among those who had injected drugs over the last month, 36.9% had used a non-sterile needle, and 12.6% had practiced shared injection. Over the past 12 months preceding the interview, 30.4% had sold sex for money, drugs, goods or a favour. In the multivariate analysis, the prevalence of HIV had a positive association with age, while having above high school education, and permanent job were protective. Conclusions Unsafe injection, and sexual risk behaviours are still frequent and the prevalence of HIV among PWID remains high. Intensified efforts are needed to prevent the further spread of HIV among Iranian PWID and their sexual partners.

  • Risk and vulnerability of key populations to HIV infection in Iran; knowledge, attitude and practises of female sex workers, prison inmates and people who inject drugs
  • 2014
  • Ingår i: Sexual Health. - 1449-8987. ; 11:6, s. 568-574
  • Tidskriftsartikel (refereegranskat)abstract
    • Background: In this study data of three national surveys conducted among female sex workers (FSW), prison inmates and people who inject drugs (PWID) were presented and compared in relation to knowledge, attitude, and practises. Methods: The surveys were conducted in 2009 and 2010 and included 2546 PWID, 872 FSW and 5530 prison inmates. Knowledge, attitude and practises towards HIV were measured through similar questions for each category. Results: Over 90% of all participants had ever heard of HIV/AIDS, although only approximately half of them perceived themselves at risk of contracting HIV. More than 80% were able to correctly identify the ways of preventing the sexual transmission of HIV; while more than two-thirds did not use condom in their last sexual contact. Approximately 20% of prisoners and FSW had a history of injecting drugs. Among all participants who have injected drugs, prisoners had the highest unsafe injecting behaviour at the last injection (61%), followed by FSW (11%) and PWID (3%). Conclusions: Despite major efforts to control the HIV epidemic in Iran, the level of risk and vulnerability among prisoners, FSW and PWID is still high. The level of comprehensive knowledge about HIV/AIDS is relatively good; however, their risk perception of contracting HIV is low and high-risk behaviours are prevalent. Therefore, HIV prevention programs should be redesigned in a more comprehensive way to identify the best venues to reach the largest number of people at a higher risk of contracting HIV and decrease their risk overlaps and vulnerability factors.

  • Molecular Survey of Tularemia and Plague in Small Mammals From Iran
  • 2018
  • Ingår i: Frontiers in Cellular and Infection Microbiology. - : Frontiers Media S.A.. - 2235-2988. ; 8
  • Tidskriftsartikel (refereegranskat)abstract
    • Introduction: Plague and tularemia are zoonoses and their causative bacteria are circulating in certain regions of Iran. This study was conducted to investigate potential disease reservoirs amongst small wildlife species in different regions of Iran.Methods: Rodents, insectivores and hares from 17 different provinces of the country were collected in 2014 and 2015. Samples were taken from the spleens of the animals and Real-time PCR was applied to detect nucleic acid sequences that are specific to Francisella tularensis and Yersinia pestis, respectively.Results: Among 140 collected rodents, 25 distinct species were identified out of which five were the most common: Microtus paradoxus (21% out of 140 rodents), Apodemus witherbyi (12%), Microtus irani (11%), Mus musculus (11%) and Microtus socialis (10%). Seventeen insectivores were collected and identified as Crocidura suaveolens (82%) and C. leucodon (18%). Fifty-one hares were collected and identified as Lepus europaeus (57%), Lepus tolai (14%) and Lepus sp. (29%). Three out of 140 explored rodents (1.91%) were positive for F. tularensis, an A. witherbyi, a Mus musculus domesticus, and a Chionomys nivalis collected from Golestan, Khuzestan and Razavi Khorasan provinces, respectively. Two hares (3.92%) were F. tularensis-positive, a L. europaeus from Khuzestan and a Lepus sp. from the Sistan and Baluchistan province. None of the tested animals were positive for Y. pestis.Conclusion: This is the first report of direct detection of F. tularensis in mammals of Iran and the first-time observation of the agent in a snow vole, C. nivalis worldwide. The results indicate that tularemia is more widespread in Iran than previously reported including the Northeast and Southwestern parts of the country. Future studies should address genetic characterization of F. tularensis positive DNA samples from Iran to achieve molecular subtyping and rule out assay cross-reactivity with near neighbor Francisella species.
