Aerosol Transmission of Infectious Disease
Objective: The concept of aerosol transmission is developed to resolve limitations in conventional definitions of airborne and droplet transmission. Methods: The method was literature review. Results: An infectious aerosol is a collection of pathogen-laden particles in air. Aerosol particles may deposit onto or be inhaled by a susceptible person. Aerosol transmission is biologically plausible when infectious aerosols are generated by or from an infectious person, the pathogen remains viable in the environment for some period of time, and the target tissues in which the pathogen initiates infection...
Exposition aux bioaérosols dans deux milieux professionnels
Les cabinets de dentistes et les cultures de concombres et tomates L'exposition aux bioaérosols (1) (endotoxines, bactéries et spores de champignons en suspension dans l'air) et les problèmes de santé qui en découlent sont bien connus dans certains milieux professionnels (station d'épuration des eaux usées, élevages d'animaux, traitements des déchets organiques, travailleurs du bois, récolte et manutention des céréales, agriculture…). Cependant, les études avec investigations des concentrations...
Bioaerosol emissions from waste composting and the potential for workers’ exposure
Composting organic waste is an important component of the waste management process in the UK and the strategy to reduce waste to landfill, and as a result there has been an increase in the number of commercial composting operations. Microbiological activity is fundamental to the composting process, therefore any handling of composting material is likely to make airborne significant quantities of those micro-organisms (referred to as bioaerosols). Workers mechanically handling compost on these sites may therefore be at risk of considerable exposure to bioaerosols depending on their work task, their...
