Antimicrobial spray products are used by millions of people around the world for cleaning and disinfection of commonly touched surfaces. Influenza A is a pathogen of major concern, leading to up to 49,000 deaths and 114,000 hospitalizations per year in the United States alone. One of the recognized routes of transmission for influenza A is by transfer of viruses from surfaces to hands and subsequently to mucous membranes. Therefore, routine cleaning and disinfection of surfaces is an important part of the environmental management of influenza A. While the emphasis is generally on spraying hard surfaces and laundering cloth and linens with high temperature machine drying, not all surfaces can be treated in this manner. The quantitative microbial risk assessment (QMRA) approach was used to develop a stochastic risk model for estimating the risk of infection from indirect contact with porous fomite with and without surface treatment with an antimicrobial spray. The data collected from laboratory analysis combined with the risk model show that influenza A infection risk can be lowered by four logs after using an antimicrobial spray on a porous surface. Median risk associated with a single touch to a contaminated fabric was estimated to be 1.25 × 10−4 for the untreated surface, and 3.6 × 10−8 for the treated surface as a base case assumption. This single touch scenario was used to develop a generalizable model for estimating risks and comparing scenarios with and without treatment to more realistic multiple touch scenarios over time periods and with contact rates previously reported in the literature. The results of this study and understanding of product efficacy on risk reduction inform and broaden the range of risk management strategies for influenza A by demonstrating effective risk reduction associated with treating nonporous fomites that cannot be laundered at high temperatures. 相似文献

提出了一种用于测试交换结构性能的仿真信源的实现方案,其内容包含两种形式的交换结构信源:一种是均衡业务下的具有地址突发的信源,用于验证交换结构所需的缓存大小;另一种是非均衡的业务源,用于验证交换结构的仲裁算法的性能。经仿真证实,此模型能很好地满足测试交换结构性能的需要,有助于交换结构的研究。 相似文献

研究了直接互连结构DIN应用到数据交换中存在的问题。针对数据交换应用特性,对DIN中的吞吐量、时延、路由算法和死锁解决策略进行了分析。研究表明,DIN中的理想吞吐量与结构规模的倒数成正比。把DIN应用到数据交换结构中,源路由表技术和最短路径算法更适合,采用死锁恢复机制能更好的利用系统资源。 相似文献
