It would certainly blow their “tried and true” theory out of the water......there are other possibilities:
1) she carried the contamination on her body, clothes, purse etc. home to him basically exposing both of them at the same time
2) they contracted the virus together from another source other than Duncan
3) the CDC us wrong about being contagious only upon the onset of symptoms
Likely #1. Hopefully.
She may have adjusted the exam light above him before putting on her gloves, because she was drying her arms after scrubbing up. Warm light within sneeze, cough range of Duncan.
I'll take #3 for $1,000, Alex
