So, those who hung around him while he was sick and vomiting - and taking no precautions - didn’t come down with it, but heavily protected health care workers did?
Kinda odd, don’t you think?
Back at the apartment there is little doubt that Jallah knew he had it (she said she was learning about symptoms on TV). She probably told her kids not to touch. The other thing is that every patient is different in the amounts of virus they will shed given various symptoms. IOW, even if Duncan were vomiting a lot, it doesn't mean he was shedding a lot of virus in the vomit. He may have vomited into pillows and kept it from splashing around. There are many unknowable factors.
What, you think it’s a conspiracy?
The staffers caught it because it as the sickness advances, more virus copies are made and expelled.
Not at all. In the crisis phase, the Emory patients had TEN BILLION virus particles/cc of sweat. This compares to FIVE MILLION/cc of BLOOD in terminal AIDS.
The health care workers are being contaminated by inadequate protection and/or when taking off their gear. Casual contact is near zero risk.
