So, interesting. I just got a call from Idaho State Health. Apparently they (eventually) follow up with phone interviews for any positive cases in the state. Mostly asking how I'm doing, verifying my whereabouts for 48hrs prior to initial symptoms, then checking if I have questions.
I had one question: Do they recommend getting another test to verify that I'm negative. She told me not to, because enough of the virus can remain (for lack of a better layman's description) for up to three months for you to test positive after your symptoms have ended. She said they just tell people to go on about their business after ten days.
Which kinda got me to thinking about all the "proof of negative test required" crap being bandied about these days. That could mean that you're essentially in quarantine from doing those "proof required" activities for three months after getting over the bioweapon, because you still might test positive.
Again, this was just Idaho State Health. I don't know what other gov entities say. I don't know if this is policy or science.
