We had an "outbreak" of parainfluenza on our floor(3 patients, same strain) so any workers with cold symptoms had to be swabbed. I came back negative but I wonder what the point was. I was swabbed on a Friday, didn't get my result til Monday, had to work all weekend(masked of course), was told I could come to work even if positive as long as no fever. Is this just a tracking thing for epidemiology? What's your experience?
