The identification of asymptomatic infection was so striking and important that Hiroshi Nishiura used it as a basis to estimate fraction of infections that are truly asymptomatic (around 1/5), validated by subsequent meta analyses https://t.co/ISgoOOO23B

@DrJenGunter (2/x) Data from DP cruise (18%, 95%CI: 15-20%) & South Korea (31%, CI: 8-54%) suggest that overall, the asymptomatic proportion might be in the 20-40% range (not including those who later show symptoms). https://t.co/pJsfxRpdKF https://t.co/3RG2orEVt1 https://t.co/wn3iMw4fj3

Also in February 2020, Nishiura et al used a simple Bayesian analysis of a set of Japanese evacueees from China to estimate the fraction of always-asymptomatic cases of SARS2 at ~30%, with a wide 95% confidence interval of 8 - 54 percent. https://t.co/ekaB8O0FDm
