Okay the stomach virus...

Okay so I have 10 days before I get induced and my oldest got the stomach virus 2 times this week and I threw up once yesterday...I have sprayed Lysol but is that enough to keep the new baby from getting sick as soon As she get a here? He didn't play with anything of hers but i know a baby's immune system is delicate and not strong...what else should I do to keep her from getting sick? Or do u think it'll be ok a by then...
