Kavod HaRav, Is tumah contagious? Like, if you for example touch your bare feet and then touch your phone or a doorknob or something, do those objects become impure as well? Also, entering a bathroom causes one to have to do netilat yadayim because of the impurity, but is this the same kind of impurity as overnight impurity when you sleep? For example with overnight impurity I have heard you should not enter your crevices such as ears or eyes with your hands, but if someone is inside the bathroom can he do so? Thanks a lot!
