Quantifying SARS-CoV-2 infection risk within the Apple/Google exposure notification framework to inform quarantine recommendations 2020-07-19 .txt text/plain 10689 493 48 The conditional probability of current or future infectiousness, conditioned on how long post-exposure an exposed individual has been free of symptoms, decreases during quarantine, with shape determined by the distribution of incubation periods, proportion of asymptomatic cases, and distribution of asymptomatic shedding durations. Findings: As an example of our calculations, fifteen minutes of close contact with a high-shedding individual, given a 15% asymptomatic infection rate and no testing, would require 5and 14-day quarantine for their risk of current or future infectiousness to fall below 0.84% and 0.14% risk, respectively. A similarly maximal interaction, i.e. with 30 minutes in each attenuation bin, but with an index case at the minimum Transmission Risk level, corresponding to exposure timing that is not risk-free but falls just outside the window currently used by manual contact tracers, yields an infection probability of 0.36%, requiring 7 days of quarantine. ./cache/cord-299343-gsrgf4dd.txt ./txt/cord-299343-gsrgf4dd.txt
