Adding This: in my State, a 6 month old baby died... because he got Pertussis from a relative. The relative had a "cold" and did not know it was Pertussis. In an adult, Pertussis has different symptoms. But the baby got sick from her, and he died. The parents just thought he then just had a "cold." This was at a family gathering.
You are not being a self-centered Mom nor a germaphobe. You are thinking. And that is good.

This is a very recent article, about Pertusis Epidemic, right now.
My kids are late born.
Because of that, I DID NOT take them to the Holiday family gatherings, nor did I have any at my home. And I didn't care what relatives thought.
You cannot just assume that in November, it will be okay by then or by Thanksgiving. There is no way to predict nor assume, that no one will get sick at that time. And your baby will still be an infant at that time, and not having gotten all of her/his vaccinations yet.
As I said, the baby in my State that died from Pertussis, he was 6 months old! The parents are now, very strongly advocating the vaccination and preventative measures, per Pertussis. My local news stations even had a special presentation on this baby that died and about Pertussis. And even our local Health Department, put out another warning about it to the general public. Advocating as well, the Booster vaccinations for Pertussis, for older children and adults.
Then, for a layperson, if they are sick... most people just assume it is a "cold." They don't go to the Doctor for it and just ride it out. So for the typical layperson, IF they are sick... how would a non-professional KNOW if they had just a "cold" or Pertussis? Only a Doctor can diagnose that properly. But only if a person actually goes to the Doctor if they are sick.
