You said it in your description: "whooping noise." Everyone in my family has had this Whooping Cough, a.k.a Pertussis, this season. It started with my 16-yr.-old; then to my 1-yr-old (vomit inducing), then my husband and me. It skipped my 2 1/2 yr. old, but he also had an extended high fever, which must have killed the bacteria.
I only realized it was whooping cough today.
