Asymptomatic transmission might be not very high, but presymptomatic transmission is very high. It is well established fact, that people are the most contagious right before onset of the symptoms.Keep in mind that the symptoms might be very mild. |

Actually if you read the meta-analysis I linked, 0.7% secondary attack rate covers both presymptomatic and asymptomatic.
