Thank you very much for the response. Same to you!
Domestic transfer in a household is extremely rare to non existent. It requires blood to blood contact and would be most likely a result of direct, through-the-skin exposure to the blood of an infected household member. Yes it is recommended not to share personal items i.e. tooth brush, razors, nail clippers, etc. Anything that could carry blood. If you have concerns keep your brush in another area.
But basically you have almost zero risk.
