Here is another scenario. Mr. Duncan may have assumed that once he was admitted to a US hospital, and received the best healthcare in the world, recovery would ensue. He then faced two possible futures. One in which he knowingly brought Ebola to a formerly Ebola-free country, and one in which he did it entirely unknowingly/by accident. I.e.: one bleak w, so far as he knew, possible legal repercussions, & one in which he could blamelessly pursue his plans for marriage and permanent US residency.
Every single early report stated as fact that Duncan & the others were trying desperately to get the pregnant woman into the ***Ebola*** ward of the hospital, NOT the maternity ward. After the ‘Duncan was totally innocent’ meme emerged, a whole lot of whitewashing went on. [Though even then, no one claimed the pregnant woman in a life-threatening crisis was turned away from the ***maternity*** ward because it was full; the story that she was turned away from the *Ebola* ward because it was full remains unchallenged.] Doesn’t take a mind-reader to see what happened. Liberia said they would charge Duncan with a crime, & suddenly ‘things changed’.
You are correct, the young woman (reportedly the daughter of Duncan’s landlord) was pregnant but also showing signs of full-blown Ebola and that’s why she was taken to the hospital. They were turned away because the Ebola ward was full. The woman returned to her parent’s home and died that evening.
As I posed on another thread a few weeks ago, the connection between the woman and Duncan has not been fully explored. From what little we know, it appears the woman and her family lived in Monrovia—the same city where Duncan resided with her parents. If she visited her parents on a regular basis, there’s a pretty good chance Duncan came into contact with her well before the taxi incident, which could radically alter Ducan’s exposure timeline and the period when he was contagious.
