“why was this guy so arrogant he didn’t self-quarantine?”
Doctors and pilots often think they are bullet-proof.
When dealing in life-and-death, it’s likely a requirement.
I someone rationalize on CNN that because the docs of Doctors without Borders work so hard and are under-paid, they should not have to go through trouble of an enforced quarantine here or stay in the west African country until they are clear.
The news anchor just let that go.
