I'm sorry you're all ill and I hope eveyone is better soon. Sounds like the flu to me. Did you all get your flu shots? They work and you can't get the flu from them because you're injected with dead virus. I don't mean to sound preachy but I'm a nurse and I work in infection control. Clean all your surfaces (like phones) with a germacide (bleach or Lysol work)that way there's less chance of it recirculating.
