K.V.
I would also add that you use a disinfectant spray like Lysol on all of the door knobs and light switches at least once a day, until the illness is gone. You change a diaper or clean up vomit and them open the bathroom door, turn on the light switch, then wash your hands and reinfect yourself on the way out when you touch the switch and door knob again. Don't forget to do the front door and main switches, once a day too, until the illness is gone.
