He simply could not have made the decision to come to the US after being probably exposed.
The ticket was purchased two weeks before he traveled and therefore long before exposure. The process for getting a visa probably started at least two or three months before that.
So when he got on the plane he was simply implementing longstanding plans.
Though arguably he should have made the decision not to travel for fear of contaminating unaffected people. Although it's unclear why we should expect individual foreigners to impose travel restrictions on themselves the US government isn't bothering to impose.
It's clear to me there is only one person to blame for this and his initials are FUBO.
Thanks for the clarification, Sherman Logan.
AOL news (huff?) is reporting that Liberia has filed criminal charges against Duncan for lying on his health form (didn’t say when this form is actually filled out). Duncan is now listed as ‘critical.’
AOL also reports the US has placed Duncan’s family on court-ordered mandatory quarantine, including five school-age children, after the family refused to comply with a voluntary request to quarantine. This is the son’s family, the son being the one who called the CDC about his father in the first place. (stupid is as stupid does)
