 The UK has seen a dramatic decrease in contact rates since the implementation of physical distancing measures. Based on data collected from a survey of UK citizens, it appears that the average person now makes 2.8 contacts per day, which is a 74% reduction from the average of 10.8 contacts per day prior to the lockdown. This suggests that the UK's R0 value has decreased from 2.6 to 0.62, indicating that the virus is no longer able to spread as quickly due to the physical distancing measures.
