A poster outlining precautions for airborne transmission in healthcare settings. It is intended to be posted outside rooms of patients with an infection that can spread through airborne transmission. [1] Video explainer on reducing airborne pathogen transmission indoors
Aerosol droplets produced by flushing the toilet can mix with the air of the room, [8] larger droplets will settle on surfaces or objects creating fomites (infectious pools) before they can dry, like on a counter top or toothbrush; [7] [10] and can contaminate surfaces such as the toilet seat and handle for hours, which can then be contacted by hands of the next user of that toilet.

On porous surfaces, studies report inability to detect viable virus within minutes to hours; on non-porous surfaces, viable virus can be detected for days to weeks. [ 2 ] [ 14 ] However, further research called into question the accuracy of such tests, instead finding fomite transmission of SARS-Cov-2 in real world settings is extremely rare if ...
Bacteria often attach to surfaces and form dense aggregations called biofilms [51] and larger formations known as microbial mats. [52] These biofilms and mats can range from a few micrometres in thickness to up to half a metre in depth, and may contain multiple species of bacteria, protists and archaea.
Microorganisms growing on an agar plate. Sterilization (British English: sterilisation) refers to any process that removes, kills, or deactivates all forms of life (particularly microorganisms such as fungi, bacteria, spores, and unicellular eukaryotic organisms) and other biological agents (such as prions or viruses) present in fluid or on a specific surface or object.
