Oooh, I'm mad

So the new worker called me today to tell me that the baby was going to have a visit with her mom.

Apparently the baby's mom got a note from a doctor saying she doesn't have the horrifying skin condition, and that's good enough for the worker!

Problems:
1. The note is from the same facility that misdiagnosed the child THREE TIMES, even though I insisted they test for this issue at her first visit there. (They did, and said she didn't have it.)
2. The mom told the old worker three weeks ago that she had, in fact, been diagnosed with it. Even if she had gotten the treatment, it's incredibly unlikely (like, just about impossible) that she'd be symptom-free by now.
3. We got the old worker to agree that BOTH parents would be treated before EITHER parent would resume visits, and that the parents needed to be treated in the same span of time (ideally twenty-four hours) in order for it to be considered effective.
4. We only have the mom's word that the dad has been treated, because neither worker has been able to get in touch with him in weeks.
5. The dad's house has not been treated. The worker assured me that she told them repeatedly how important it is for the house to be treated. Pardon me for not being reassured.
6. If the baby gets reinfected, that means time out of daycare for her, which means time out of work for me. Cool. For those of you who think that should matter less since the county pays us to be foster parents, let me tell you that the $0.59 an hour I make as a foster parent is a small fucking comfort when it comes to time off from work.
7. The worker has not called me back to tell me if the visit even actually took place - all I know right now is that the medical transport company picked her up from daycare and dropped her back off, but there is a slim chance that the worker forgot to cancel the transport (it's her first week with this case) so the baby just hung out with the visit supervisor. Naturally, I can't get anyone on the phone to confirm this, so:
8. I will now be bathing the baby, and washing her carseat cover and diaper bag along with its contents.

I know we have no rights as foster parents, and I know it's in our best interest not to piss off the worker on her second day in our case, but hey, guess what? I'M NOT GOING TO BE OKAY WITH THIS. I left her a message asking her to let me know if she's going to let the dad have his scheduled visit tomorrow, that I officially request that it not take place until we know the home (and his five-year-old and his mom, who live there) have been treated, that I know I'm making her job harder and I apologize for that but I'm not comfortable with the baby being reexposed to an infectious disease, that I can get notes from the doctor indicating that the parents need to be treated in the same time span, and to call me in the morning.

Ugh. Okay, vote time: Should I call the worker's supervisor to make sure this is being taken seriously, or do you think that will just make things more complicated?
