I had same reaction, it happened in Torino, Italy. I've no idea why I am being downvoted for reporting simply what she told me.
I asked her again, now it's confirmed it's Coronavirus. It takes time to get lab test, they can't confirm it immediately it seems for now.
They're doing a labtest for Coronavirus because she's been in contact with a nurse who's been in contact with a Coronavirus patient. It is just standard protocol to get tested in that case.
Calling it Corona is just my speculation based on who she worked with in the clinic where she's a nurse.
