“But asymptomatics are not going to be all that contagious/transmitting, (I’m sure R0 pretty low), because they wouldn’t be coughing and sneezing much, by definition.”
However, we do know as a fact that asymptomatics can be contagious. Plenty of examples. It has been documented a number of times right here on FR. So even if they have a low R0 themselves, their victims will not necessarily and it will snowball. All that does is slow down the first generation or two until you get a symptomatic and another outbreak.
Have you ever noticed how much some people spray when they talk? Or stick their fingers in unfortunate places and then smear everything they touch? Some would only have to kiss their spouse to set it off, or smooch one of the kiddies (who themselves are the most likely asymptomatic carriers) goodnight and then *that* little disease reservoir is off to the races.
