Crimean-Congo Haemorrhagic Fever (CCHF) is a viral zoonotic disease. Butchers and slaughterhouse workers are considered to be high risk occupational groups for the disease. Sistan and Baluchistan province is an area in southeastern Iran which is endemic for CCHF, and the most confirmed cases of the disease are reported from this province. The aim of this study was to investigate the seroprevalence of CCHF and risk factors for seropositivity among them in Sistan and Baluchistan province in 2011.
Questionnaire data and blood sample collection were carried out for each participant and the sera samples were sent to the national reference laboratory for ELISA IgG testing.
In this study, the seroprevalence of CCHF among 190 butchers and slaughterhouse workers from 11 counties was 16.49%. 79% of participants were aware that they were at risk of zoonosis and 39.7% did not use any personal protective equipment during their work. Of 31 CCHF IgG positive individuals in this study, eleven individuals had a previous record of CCHF infection in 57 months prior to the study.
High seroprevalence of CCHF among butchers and slaughterhouse workers and minimal use of personal protective equipment's during daily work indicates the need for training courses, for these groups to increase their knowledge, attitude and practice with respect to zoonosis.
克里米亚-刚果出血热（CCHF）是一种病毒性人畜共患病。屠夫和屠宰场工人被认为是该疾病的高风险职业群体。锡斯坦-俾路支斯坦省是伊朗东南部的一个地区，是CCHF的地方性流行区，该省报告的该疾病确诊病例最多。本研究的目的是调查2011年锡斯坦-俾路支斯坦省CCHF的血清流行率及其血清阳性的危险因素。
对每位参与者进行问卷调查数据收集和血样采集，并将血清样本送至国家参考实验室进行ELISA IgG检测。
在本研究中，来自11个县的190名屠夫和屠宰场工人中CCHF的血清流行率为16.49%。79%的参与者意识到自己有人畜共患病风险，39.7%的人在工作期间未使用任何个人防护设备。在本研究的31名CCHF IgG阳性个体中，有11人在研究前的57个月内有CCHF感染记录。
屠夫和屠宰场工人中CCHF的血清流行率较高，且日常工作中个人防护设备使用极少，这表明需要为这些群体开设培训课程，以提高他们关于人畜共患病的知识、态度和实践能力。
