Legionnaires’ disease in transportation, construction and other occupations in 39 US jurisdictions, 2014–2016
研究分析了2014-2016年美国39个州2553名军团病患者的职业数据，发现交通和建筑工人患病风险显著高于其他职业，其中卡车司机和建筑工人占比最高，建议使用含杀菌成分的挡风玻璃清洗液降低风险。
Background Certain workers are at increased risk for acquiring Legionnaires’ disease compared with other workers. This study aims to identify occupations at increased risk for acquiring Legionnaires’ disease. Methods Using data from the US Centers for Disease Control and Prevention’s Supplemental Legionnaires’ Disease Surveillance System, this study identified Legionnaires’ disease confirmed patients ≥16 years of age in 39 states with reported symptom onset during 2014–2016. Age-adjusted and sex-adjusted incidence rate ratios (IRR) stratified by occupation group were calculated by comparing Legionnaires’ disease patients in an occupation group (eg, transportation) to those in all other occupation groups (eg, non-transportation). Results A total of 2553 patients had a known occupation group. The two occupations with the highest burden were transportation (N=287; IRR=2.11) and construction (N=269; IRR=1.82). Truck drivers comprised the majority (69.7%) of the transportation occupation group and construction labourers comprised almost half (49%) of the construction occupation group. The healthcare support occupation had the highest IRR (N=75; IRR=2.16). Conclusion Transportation and construction workers, who are generally not covered by guidance related to building water systems, have increased risk of Legionnaires’ disease compared with other workers. One hypothesised risk factor for truck drivers is the use of non-genuine windshield cleaner in their vehicles. A simple intervention is to use genuine windshield cleaner with bactericidal properties (ie, includes isopropanol/methanol) which can reduce the risk of Legionella growth and transmission. To improve surveillance of Legionnaires’ disease and identification of similar exposures, the authors encourage the collection of occupation and industry information for all patients with Legionnaires’ disease.
