37 weeks and everyone in house is sick

My whole family has been sick with SOMETHING for the last 3 weeks. Our 11 month old went to urgent care with 103 fever from a virus. My husband had bronchitis / virus. My son has had some virus too. My nose is runny but that's it so far. Well now my son has been tested with Flu Type A. I think my husband has had the flu too because he shows all the symptoms. Our 11 month old has a runny nose again. ughhh. My husband and son don't see it as a big deal. I'm like, the baby can be here any day and could die if she got the flu. Stay the hell away from me!!!! My doctor prescribed me Tamiflu to take as precaution... then my muscus plug came out today so I'm just hoping the baby doesn't arrive until after all these sicknesses are gone!! Its a vicious cycle once someone gets sick. 🙄 any tips???
