Using detailed survey information on social encounters coupled to predictive models, we investigate the likely efficacy of the current UK definition of a close contact (within 2 meters for 15 minutes or more) and the distribution of secondary cases that may go untraced. Using preliminary estimates of COVID-19 transmission (average latent period 4 days, average effective infectious period 1.61 days, R 0 =3.11 and assuming a simple SEIR formulation (Read et al 2020)) we compute the distribution of epidemiological, social and contact tracing characteristics across the population.	./cache/cord-257801-rgzmpoxv.txt	./txt/cord-257801-rgzmpoxv.txt
