Your tooth brush is going to be a safe habitat for a lot of germs including E.Coli (a bacteria that cause diarhoea) if you leave it uncapped.
It is not a better idea to keep your brush in a toilet as toilet flush sprays a pretty large number of germs into the air.
So always keep your tooth brush covered and replace it with a new one frequently to keep germs away from yourself.
Remember that our body is capable to kill thousands of germs on daily basis, so donâ€™t be panic but taking some steps to safe guard your health is not bad.
This is a great reminder. Toothbrushes should also be changed often and washed thoroughly with clean water before and after every use.
