I use to work in 'centre care' for 20 years so wearing disposable gloves to diaper or handle any 'bodily fluid' such as blood or vomit was a public health requirement as part of the 'Universal Precautions' for HIV and AIDS - we had to keep gloves on hand at all times 'just in case' ... so I am use to having to wear gloves while diapering squirmers and so forth - like a 'surgeon' when you wear them consistently with practice you can learn to do fine delicate work in them - you just have to get them on and prepared before starting to actually 'diaper' the child.

That said now that I work from home and am my own boss I can make my own rules based on the 'risks; I am willing to take in my job - so I only wear them if changing a really disgusting poop or dealing with blood or vomit ... otherwise I use a 'kleenex or wipe' to scoop out any diaper cream and apply it with the same so as not to contaminate their container with MY germs or me with theirs - it is still a 'barrier' from skin to skin contact just quicker and easier to work with. When dealing with a normal 'poop' I can clear away as much of the poop with the actual diaper front wiping front to back with it fold it up and set it aside and than use a wipe just to make sure the surface is entirely clean but again the wipe is always my barrier so I never actually touch them.

I also make sure I carry two to three pairs with me when we are out and about in a ziplock bag for emergencies and so forth....they have come in handy at the local park when it was used by someone for a 'meet up' and left behind their used protection - put on the glove to pick up the condom and than pulled the glove off carefully so the glove turned inside out and became the 'bag' for the garbage and threw it into the trash and than used hand sanitizer just in case.

The bottom line is what you are comfortable with ... urine and feces care bacteria and germs for sure and ensuring you have a barrier between them and your skin is ideal as well as ensuring proper hand washing practices as well!
