Do viruses/bacteria have some motive mechanism? I mean if the virus/bacteria reach some surface by touching, can it move on that surface?
Life example: suppose the cooler is not so clean and has some viruses on his surface. My cup came into contact with the cooler in some little area, so virus migrated to that little area of my cup. Can the virus eventually move to another area of my cup's surface? Or can I be sure that it remained at the point of contact? If yes, is this also true for bacteria?
P.S. obviously parasites can move, but I can't figure out are the viruses and bacteria can..
