According to some experts, the harm factor responsible for the diseases existing, are the bacteria like streptococcus and E. coli. The skin on our backs serves as an active, protective shield. We are not convincing you to avoid uncovered toilet paper in public toilets. But it’s always better to use your own toilet paper.
Toilet bowls are designed by manufacturers with solid surfaces, on the way for germs to stick on to. So they are not as dirty as we doubt they are. When there is a metal or plastic cover over the toilet paper roll, then you are lucky. It protects the paper roll from the germs.
It is recommended to keep a pack of tissues (or wet tissues) with you to use in these emergencies. Or you will have to rely on the tried and practice of squatting. Holding it in you and risk an accident or possibly as long as there’s enough toilet paper you can cover the seat and do your urge. Don’t forget to close the lid of the toilet seat before the flush. Because the cover of the toilet seat will prevent spreading the germs in the air and over the toilet paper.
