Can you get a disease from sitting on a public toilet seat? [closed]

If you don't have any injuries on the parts of the skin which touch the toilet seats, it's very unlikely that you catch an infection from the germs there. Remember, that in the whole environment our body is exposed to uncountable germs, and we still don't get sick. If you would have open wounds, it would be a different issue, but then i guess you wouldn't even sit down.

Carrying disinfectant certainly helps. There are travel sized kits with wipes, spray and hand gel. I also carry one of those, just to be safe. It is though more important to wash your hand properly and disinfect those, because that's the main entry point how you can infect yourself or other people (e.g. by eating with infected hands etc.). In case of eating, e.g., the germs are exposed to your mucosa, which is easier to pass than your skin.
