dr. michael edmund running epidemiology at university of iowa hospitals. i want to introduce as well here on the set, anthony ronnen, an expert on medical malpractice, and infection management protocols. thanks to a knowledgeable panel here. i want to start with you, doctor. when we talk about someone being on this plane, having that escalated temperature n your view, just based on the public information, were other passengers on the plane at risk? >> i think they're probably at very low risk because i think one of the things we're learning about ebola disease is that early on in the course of the infection, the patients are very minimally infectious. i think the dallas case has demonstrated that. >> a lot of questions about this second ebola patient, amber vinson. what this comes down to, though, is that they she just should not have gotten on that plane. there were certain guidelines in place, if you're in contact with someone with ebola you shouldn't have gotten on the plane. she had a slight fever, 99.5. regardless, she shouldn't have got not on plane.
