In S.E. Michigan, Macomb County I'm frequently hearing "COVID positive" or COVID negative" or things like "no known COVID cases in the home", things along those lines.
Lancaster PA uses these terms primarily..
Potential/Possible PUI (not Confirmed)
Confirmed PUI
Non PUI
depending on the dispatcher "PUI" & "Covid" are interchangeable.
And the more illusive "Did you copy the additional in CAD"
Police are Encrypted, can't hear them..
In Leavenworth, KS the PD, Fire, and EMS have been using he/she is COVID Positive or they have a + or - Viro screen (Note: I maybe not spelling "Viro' the right way. )
I thank the Lansing Correctional Facility has been calling them "COWS" I don't know if that is right or not. But I do hear that a lot and after asking someone that use to work for them.. she says that is what they call the sick ones.
