Title: Quantifying the impact of physical distance measures on the transmission of COVID-19 in the UK Document date: 2020_4_3
ID: 8do4tojk_52
Snippet: The total number of daily contacts (mean of 3.1 per person) was significantly reduced compared to patterns previously estimated in the POLYMOD study (10.7 ; excluding children <18 years old) and more recently by the BBC Pandemic study (10.5 ; excluding under 13-year-olds) 16 . The observed reduction appears to be unlikely due to chance given the large difference in average contacts, and is consistent with a recent study conducted in Wuhan, China .....
Document: The total number of daily contacts (mean of 3.1 per person) was significantly reduced compared to patterns previously estimated in the POLYMOD study (10.7 ; excluding children <18 years old) and more recently by the BBC Pandemic study (10.5 ; excluding under 13-year-olds) 16 . The observed reduction appears to be unlikely due to chance given the large difference in average contacts, and is consistent with a recent study conducted in Wuhan, China that estimated a reduction in the average number contacts per day from 14.6 prior to the outbreak to 2.0 under physical distancing interventions 12 . While we are unaware of any directly comparable data from the UK, our findings are certainly consistent with other reports from the UK of a dramatic reduction in social contacts, with, for example, only half of respondents in one survey reporting having the house at all in the past 24hrs 4 .
