sick 3 yr old 2 days before csection

Freaking out. My son woke up sick this morning... stuffy runny nose and that's mostly it. He's not playing as much but no fever in sight. I have been washing my hands like crazy. But I can't stay away from my cuddly sick 3 yr old when I'm the only one home with him and my husband is working. But it doesn't help that everyone at my job is sick and my husband just said everyone at his job tried to call out sick today. Ughhhh what will we do!
