Newborn exposed to illness

My baby girl is 2 days old, we literally just brought her home last night & this afternoon, my husband (who has been helping care for her) woke up feeling sick & now has a fever of 102. Obviously he is staying away from her now, but I am such a wreck. I am breastfeeding & hope it helps.. not even sure if my milk has come in yet. Does anyone have any positive outcomes to experiencing something like this?? Or any words of advice???? I am so terrified.
