Other than family members I wonder how many others has he had interaction with? Mailman? Pizza Delivery guy, may he went to the pharmacy to get something for his ‘flu’??
He went to one medical facility and was then sent home. I figure a minimum of 6 health workers had close enough contact to become infected. I figure at least 6 more at this facility before he was off limits. Maybe 6 more “family members”. So a very conservative number of recent close, unprotected, contacts would be 18. Anyone’s guess as to how many of those actually wind up with Ebola. My guess would be 6.
If he was out and about, all bets are off.
Whoever he was in contact with, where he went will be investigated..if not already. I understand he was visiting family in Dallas and why the trip here so perhaps he hung out at their home only before he got sick.
