Fomite


My story on lift buttons [Note: Americans refer to them as elevator buttons] brings to mind a new and possibly useful 😝 word for everyone to know: fomite. It's a word associated with the spread of germs, viruses and bacteria through handling of dirty items. This information below is taken from Wikipedia, which I normally accept with a grain of salt but this one I do accept fully since it is simply a definition of a word:

A fomes (pronounced /ˈfoʊmiːz/) or fomite (/ˈfoʊmaɪt/) is any inanimate object, that when contaminated with or exposed to infectious agents, such as pathogenic bacteria, viruses or fungi, can transfer disease to a new host. For humans, skin cells, hair, clothing, and bedding are common hospital sources of contamination of fomites.
Fomites are associated particularly with hospital-acquired infections (HAI), as they are possible routes to pass pathogens between patients. Stethoscopes and neckties are two such fomites associated with health care providers. Basic hospital equipment, such as IV drip tubes, catheters, and life support equipment, can also be carriers, when the pathogens form biofilms on the surfaces. Careful sterilization of such objects prevents cross-infection.
In addition to objects in hospital settings, other common fomites for humans are door knobs, light switches, handrails, elevator buttons, television remote controls, pens, and other items that are frequently touched by different people and that may be infrequently cleaned.
Researchers have discovered that smooth (non-porous) surfaces like door knobs transmit bacteria and viruses better than porous materials like paper money because porous, especially fibrous, materials absorb and trap the contagion, making it harder to contract through simple touch. Fomites include soiled clothes, towels, linens, handkerchiefs, cups, spoons, pencils, syringes, and surgical dressings
