This is one of the million dollar questions. Based on a hunch rather than actual science, I'd say many of us are asymptomatic carriers, closer to the 50% number being floated around.Hopefully this is going on somewhere but a research lab needs to find some asymptomatic positives and put them in a controlled environment to study how contagious they are and by what means. Does an asymptomatic breathing contain a significant amount of virus? Coughing? Sneezing? Picking their nose and touching things?
Nobody knows how contagious asymptomatic or pre-symptomatic patients are. It is all just guesses and estimates at this point. I would theorize that one of two things is true:
1) They are extremely contagious and a huge percentage of the population has already been infected or;
2) They aren't very contagious and only transmit the virus in rare instances.
When the antibody test is available, if a large percentage come back with antibodies then the answer is likely #1. However, if a large number have antibodies and the answer is #2 then symptomatic patients are extremely contagious and the Ro is much higher than 2.3.
This is purely anecdotal, but at my wife's work many patients are testing positive without having any visitors. Kinda scary to think that asymptomatic providers are infecting patients, but it's plausible.
