Fig. 2
Age-stratified mean (95% plausible range) number of close contacts from survey respondents. Graphs a–c show the mean number of contacts respondents in each age group reported, by contact age group. Graphs d–f show the mean rate of contact between respondents in each age group and each other person in the target population, by contact age group. Graph g shows the overall estimated relative reduction in R0 from 2019 to 2020. Graphs h and I show the estimated proportional reductions in contact between age groups from 2019 to 2020. *Numbers shown are rates × 105
