Reports of COVID-19 cases potentially attributed to fomite transmission led to the extensive use of various disinfectants to control viral spread. Alternative disinfectants, such as essential oils, have emerged as a potential antimicrobial. Four essential oil blends were tested on three different surfaces inoculated with a coronavirus surrogate, bacteriophage Phi 6, and a bacterial indicator, . Log concentration reductions were analyzed using GraphPad Prism software. Data collected in this study show that the application of dilute essential oil disinfectants using a spray delivery device is an effective way to reduce concentrations of bacterial and viral microorganisms on ceramic, stainless steel, and laminate surfaces. Surrogate viruses were reduced up to 6 log PFU and bacterial were reduced up to 4 log CFU. Although surfaces are no longer considered a high risk fomite for COVID-19 transmission, the disinfection of microorganisms on surfaces remains an important consideration for high touch areas in hospitals, waiting rooms, etc. The application of spray disinfectants, based on essential oil blends, provides a rapid and effective means to reduce microbial contamination on high-touched surfaces.
报告称，有新冠病毒病例可能与接触传播有关，这导致人们广泛使用各种消毒剂来控制病毒传播。替代消毒剂，如精油，已成为一种潜在的抗菌剂。本研究测试了四种精油混合物在三种不同表面上的效果，这三种表面分别接种了冠状病毒替代物、噬菌体 Phi 6 和细菌指示物。使用 GraphPad Prism 软件分析对数浓度减少。本研究收集的数据表明，使用喷雾输送装置应用稀释的精油消毒剂是减少陶瓷、不锈钢和层压板表面细菌和病毒微生物浓度的有效方法。替代病毒减少了高达 6 个对数 PFU，细菌减少了高达 4 个对数 CFU。尽管表面不再被认为是新冠病毒传播的高风险接触物，但对医院、候诊室等高接触区域表面微生物的消毒仍然是一个重要考虑因素。基于精油混合物的喷雾消毒剂的应用提供了一种快速有效的方法来减少高接触表面的微生物污染。
