For example, a recent RCT showed that antibacterial-impregnanted scrubs were relatively ineffective in hospitals: https://www.cambridge.org/core/journals/infection-control-an...
This seems like a reasonable place for regulators to step in.
Airports are a controlled environment where your free will is a lot less meaningful than usual.
I'm quite fond of hand-washing, and I hate airports because they make it so difficult. You have to touch everything, and everything touches you, and sinks are few and far between, and only located in jam-packed restrooms.
You also can't bring decent quantities of hand sanitizer through checkpoints. This ban on liquids and gels applies to alcohol gel, BZK foam, povidone solution, and towelettes premoistened with any of the above. I checked.
Once aboard the plane, there's no effective handwashing. The bathrooms are so small you brush the walls with your shoulders while turning around, the trash-flap has to be shoved on to deposit your paper towel, and the door latch has to be touched to be operated.
After you've arrived at your destination, luggage at the baggage claim has been handled by folks outside your control, who themselves probably don't wash their hands very often, and once you've grabbed it, even if you wipe it down with some towelettes you've squirreled away, there's no restroom nearby to wash the remaining mostly-dead germs off your hands.
So please, tell me which airports you've been flying where handwashing is easy, and I'll try to schedule a connection through one to check it out.
You can do none of these things and be just fine.
You, personally, may not get sick traveling, but your experience is not a solution for a systemic problem, nor is your proposal of doing nothing.
> People routinely get sick when traveling to the point it's basically a trope.
The only version of the trope I've heard of before is eating in foreign 3rd world destinations (eg: Delhi belly). I live in a major tourist destination and if tourists were routinely getting sick out here I'd know about it.
I mean of course one should be washing their hands after using the bathrooom, but all that other stuff you mentioned.. that's anal to the point of obsessive.
Isn't a large value of washing after using the restroom that it means you'll wash your hands multiple times a day when you wouldn't otherwise?
> but all that other stuff you mentioned.. that's anal to the point of obsessive.
Arguments similar to this were used against washing your hands at all when we first developed a theory of germs and contamination.
Really though, this discussion won't progress until one of us has supporting data.
I don't have data to support my conclusions, but I subscribe to the Hygiene Hypothesis... humans have lived in filth for millennia, and our bodies haven't evolved to live in sterile conditions.
> Of the surfaces tested, plastic security screening trays appeared to pose the highest potential risk, and handling these is almost inevitable for all embarking passengers.
But maybe it doesn't work the same; or maybe it's just so contaminated it doesn't matter. The best solution[1], though, is probably to sell your soul to the devil and enroll in TSA Precheck.
[1] Presuming there's a real problem. Aren't the fungi that cause atheletes foot (tinea pedis) and onychomycosis (infection of the nail bed) pretty much everywhere already? I think it's more a matter of keeping your [low-temperature] extremities dry. Onychomycosis is almost inevitable past a certain age because of immune and circulatory deficiencies.
Microsurfaces on, e.g., hardwood have properties that sequester and kill pathogens. (https://news.ncsu.edu/2014/09/cutting-boards-food-safety/) However, that can also make them more difficult to clean, particularly in a commercial or industrial setting where the process needs to be low-cost, minimally labor intensive, scaleable, and reliable. Similarly, the surface properties may be difficult to maintain or restore. For example, perhaps oil build up on wood surfaces regularly touched by passers-by reduces or eliminates the antimicrobial qualities, or even make it worse than the alternatives.
That's the rub--how to design (and market) cheap hardware that is easy to maintain while maximizing antiseptic properties during use. We've optimized for the former (cheap, easy, reliable sanitation) but neglected to appreciate that actual cleanliness sucks because typical materials in high-traffic areas go from pristine to cesspools almost immediately and, crucially, stay that way until the next round of cleaning briefly sanitizes the surface.
This is aside from the fact that hospitals are a more adversarial environment than kitchens--every sneeze might contain ebola, and every patient might be immunocomprimised. I would imagine airports fall somewhere in the middle.
I wish hospitals, airports, and other shared spaces would use brass hardware or other alternatives rather than steel, particularly on door knobs and other highly trafficked surfaces. I always wondered if there'd be a market for selling such biocidal and viricidal hardware, either passive hardware using special alloys or surfaces (e.g. untreated wood performs well by locking pathogens in pores so they don't transfer readily); or active hardware that, e.g., ran a small current across the surface.
