What should I be aware of with sick people in the house?

My brother and dad are both sick and I am now just getting better, I’ll probably be 100% better by today, I was sick for six days. Yet, my brother and dad are still sick! Me and my brother don’t touch really lol, but we use the same soap, bathroom, and yea. Now me and my dad only do the cheeck to cheeck kiss thing when I say hi to him. We all use the same dishes but of course wash them before using.

So please, tell me, is there anything I should watch out for or should do to make sure I don’t catch a cold again from them!? I am willing to sleep outside for a freakin’ week to not get sick, I really really despise getting sick, it held me back so much. So please help a brother out. Thank you =D

P.S. My brother and dad only have colds, nothing more serious.
