Original Note:
Actually, the study estimated that less than 15% of COVID transmission was asymptomatic, but more than 40% was presymptomatic, so, symptomatic transmission was in minority. https://journals.plos.org/plosmedicine/article?id=10.1371/journal.pmed.1003987%20#sec022:~:text=In%20mathematical%20modelling%20studies%2C%20estimated%20proportions%20of%20all%20SARS%2DCoV%2D2%20infections%20that%20result%20from%20transmission%20from%20asymptomatic%20individuals%20were%20mostly%20below%2015%25%2C%20and%20from%20presymptomatic%20individuals%20mostly%20higher%20than%2040%25. A previous review from 2021 agrees on the instrumental role of presymptomatic transmission. https://www.clinicalmicrobiologyandinfection.com/article/S1198-743X(21)00038-0/fulltext#secsectitle0130:~:text=Modelling%20studies%20suggest%20that%20it%20is%20not%20possible%20to%20have%20widespread%20infection%20without%20substantial%20pre%2Dsymptomatic%20transmission.
