COVID-19 transmission risks associated with environmental contamination in workplace and public toiletsCOVID-19 shines a light on the challenges of controlling infectious disease transmission in society and has raised numerous questions around how our infrastructure contributes to the risk of infection. Sanitation is one area where there are known risks for a number of infections and where there is potentially a link with COVID-19 risks. The risks are thought to result from aerosolisation of pathogens from toilets which may pose a direct inhalation/ingestion risk or a risk via contaminated surfaces. Studies have measured microoganisms in air and on surfaces from a sanitation source, but there is very little assessment of the fluid dynamic mechanisms involved or the quantification of risk from air or surface exposure.This project brings together experimental studies measuring particles and biological aerosols, computational fluid dynamics modelling of aerosol dispersion from toilets, and infection risk modelling to evaluate the design and user behaviour parameters that determine risk of transmission. The project considers risks posed by the SARS-CoV-2 virus that causes COVID-19 as well as other pathogens. The project will contribute to understanding of how sanitation systems and services contribute to risk of disease and a risk assessment approach that is robust.

新冠肺炎传播风险与工作场所和公共厕所的环境污染COVID-19揭示了在社会上控制传染病传播的挑战，并提出了许多关于我们的基础设施如何增加感染风险的问题。卫生设施是一个已知存在许多感染风险的领域，也是一个可能与新冠肺炎风险有关的领域。这些风险被认为是由于厕所中的病原体被气雾化造成的，这可能会造成直接吸入/摄入的风险，或者通过受污染的表面造成风险。研究测量了空气和卫生来源表面上的微生物，但很少对所涉及的流体动力学机制或空气或表面暴露的风险进行量化。该项目将测量颗粒和生物气溶胶的实验研究、厕所气溶胶扩散的计算流体动力学模型以及感染风险模型结合在一起，以评估确定传播风险的设计和用户行为参数。该项目考虑了导致新冠肺炎的SARS-CoV-2病毒以及其他病原体带来的风险。该项目将有助于了解卫生系统和服务如何有助于疾病风险，并有助于采取强有力的风险评估方法。
