A peculiar directive I have to inquire about. Not as a standard but as a situational circumstance.
One just had a bowel movement, and wiped without making physical contact with ass or content. The bacteria that transfers through the toilet paper has how much staging presence on the hand?
Second condition person does not wash, grabs a match head from its tip and strikes it alight on the strip .
He lights a cigarette after the initial burst of sulfur expends itself .
How much bacterial has been eligible to pass from finger to match head to ignition of flame and contact to cigarette?
Disregarding finger contact to rest of cigarette or mouth as a factor of contamination.
What is the true eligible contamination factor in described circumstance ?
If the paper didn’t get wet through to the hand, and you didn’t rearrange your toilet paper for a second wipe, then you didn’t get any fecal bacteria on your hand from wiping after you pooped. (Which I believe renders the match question irrelevant.)
However, you probably have fecal bacteria on your hand from opening the door to the bathroom, from the elevator button you pressed an hour ago, from your telephone, from the counter at the security desk, from the copy machine and/or from the water cooler in the breakroom.
Fecal bacteria is everywhere. So is other bad bacteria. We don’t wash our hands after the bathroom (only) to get off any bacteria that we (may) have gotten on them in the process of going to the bathroom. We wash our hands after going to the bathroom because the bathroom has a sink (and hopefully soap) in it, and we should wash our hands several times a day. Since most of us also go to the bathroom several times a day, that’s the most efficient time to do it, and the time most people remember to do it.
Edit: If you don’t ever go to the bathroom (say you have end stage renal disease and you no longer urinate, and you have a colostomy to collect your stool) you should still wash your hands several times a day - about as often and regularly as most people go to the bathroom.
