Being symptomatic is regarded as virtually synonymous with being infectious, so if he was asymptomatic then likelihood of infecting others was low to nonexistent. We’ll see about the accuracy of that assumption, time will tell.
Really at what POINT of symptoms would infectiousness begin. no one is going to know that, I realize. But you could just be feeling crappy but not full on SICK yet and who knows if it’s kicked in to become infectious. I feel that the panic level will rise if/when the first contact comes down with symptoms.
Except he was vomiting, had a temp, sweating, red eyes, and diarrhea while at the apartment, outside the apartment, in the car, at the hospital ER the first time and in the ambulance.
