I don't think unavailability of soap posed higher risk than unavailability of the toilet by itself. I guess areas where soap/water is unavailable, they go 'Bear Grylls' of cleaning with leafs.
obviously yes, apparently general social consensus here seems it is hygienic than using paper to do the job.
At-least middle class families & above have water faucet to go along with western model toilets; though the concept of using tissue paper for cleaning shit is still alien for majority here.
