This is the problem. They have women treating these patients. We all know women will not cancel vacations for anything. If we had male nurses treating the Ebola patients the first sign of sniffles and they would go under self quarantine and watch sports for 3 weeks.
That's one strategy. Issue beer, diapers, and a remote to all exposed males.
In all seriousness, maybe the vomiting was just vomiting. Plenty of people are nauseous after a flight and don't expect it to be a big ordeal. My 13 yr old daughter has vomited after car or plane travel more times than I can count. She also gets nosebleeds if just bumped. I better be careful where I take her or they'll be throwing her in isolation....
