"Many signs point to the viral load not being highly infectious at the beginning. Duncan was sent back to his home by the hospital and lived with his fiance who was taking care of him for two days before being readmitted. She wore no PPE yet appears to be uninfected. If sitting next to someone infected on a bus or subway is enough to pass it on, there would be a million cases in West Africa by now, not 10K. It appears to be primarily caregivers at the later stages of the disease, and the custom of kissing corpses that appear to be spreading the disease because the viral load is extreme at that stage. This doesn't mean that the potential contacts of this person should not be traced or that it was good idea for him to go bowling, but the sky isn't falling just yet."

Please look at this first
People move through the stages at different rates with a high variance. That's still pretty scary.
