medical workers and first responders right now, but general public later/ But maybe since your wife has been visited a nursing home, she might qualify now? Worth a phonecall to your doc, see if you can get a referral maybe?:

One site says the test only works for people that show symptoms, but there have been numerous articles on positive tests with people that don't show symptoms - but are linked to people that got sick by them.
There was a post from some official pamphlet that said “only people that are showing symptoms can spread the virus”!! It is really unbelievable the amount of miss-information out there.
The above statement is on par with the online advice that drinking rubbing alcohol will kill the virus. Although I guess in a sense that is true. I read where numerous Russians HAVE drank rubbing alcohol and killed themselves. (I'm guessing that the virus dies with them?)
