Working with some who's family is COVID positive

[Starfish-RN]

One of the nurses I work with the other day comes in and says to me that her husband and son both have tested positive with COVID and have symptoms. She told me she was not supposed to say anything to anyone, because her boss told her not to (I can honestly appreciate her honestly, and it makes me take those EXTRA precautions around her, but I felt super uncomfortable with the way that is being handled)... seems shady to me honestly?

She went and got tested (days before her family came down with symptoms) she said it was negative, but the way she tells me how the test was done sounds sketchy. I am testing patients at the hospital occasionally and this swab is NOT a "tickle" in the nose... I am not comfortable returning to this place of employment for a few weeks ( I am PRN anyway) and honestly feel safer at the hospital in surgical services, where all our patients are rapid tested before their procedures than working with someone who's family has it and she, herself has never quarantined. I completely understand that just because you come into contact with someone who tests positive does NOT mean you are guaranteed to get it... but the whole issue about her not quarantining herself or being retested just seems super dangerous and working with patients too?

I honestly just want to get this off my chest, and want to see if I am being too "weirded" out by the situation or whether I am justified to feel this way and not wanting to return for a few weeks ( which I will keep it personal)
