Even if there isn’t widespread community transmission, it spreads at an exponential rate, which makes it very dangerous and something that is best dealt with as soon as possible. Exponential rates mean the problem looks small, and looks small, and looks small, and looks small, and then suddenly it is overwhelmingly large and out of control. It’s the old parable of the rice and the chess board

Regarding asymptomatic spread:
“ How can someone pass along coronavirus when asymptomatic? If not sneezing or coughing, how can they infect others?
It’s easy for asymptomatic people with coronavirus to spread the illness, said Dr. Anne Rimoin, an epidemiology professor at UCLA’s School of Public Health.
“Certainly when you speak, sometimes you’ll spit a little bit,” Rimoin said. “You’ll rub your nose. You’ll touch your mouth. You’ll rub your eyes. And then you’ll touch other surfaces, and then you will be spreading virus if you are infected and shedding asymptomatically.””
