If you've never had scabies... you are very blessed.
It may be too late.
My story is "typical bad". With scabies... there are only 2 types of stories. Caught a mild case very early and treated it, and caught a severe case and didn't realize for a week or two... and then had to spend the next several weeks ripping out every carpet, throwing away all fabric furnishings (couches, chairs, beds, etc.), freeze in ziplocks all things (that cannot be boiled for several hours) for 2-6 WEEKS... essentially gutting your house, boiling and freezing everying, and saturating everyone in some serious pesticides. Weeks of your life spent in total isolation, and 10's of thousands of dollars.
Scabies is the original 7 year itch. As in, before the meds and plastic, it typically took YEARS to get rid of.
Because you've been exposed, what *I* would do is "round 1". Which means
- Boil all clothes and sheets
- Steam clean all furniture & carpets (including mattresses and car)
- Completely douse in scabie-killer.
Because all that only takes a day or two, and is only a couple hundred bucks.
Because I've spent weeks and 10's of thousands.

The thing about scabies... is that you become infected via touch. Sitting in a chair that someone else sat in, shaking hands, having your coat hanging next to their coat, etc. Scabies, unlike lice (so much easier to deal with lice!), is microscopic. You can't see them, and they get. into. everything. Shudder. HATE scabies.
