From UCL/IPSOS:
“….The main findings from the sixth REACT study show that between 16th Oct and 2nd November:
Prevalence of infection was 1.3%, meaning 130 people per 10,000 were infected, up from 60 people per 10,000 in the previous report;
Regional prevalence of infection was highest in the North West (2.4%, up from 1.2%), Yorkshire and The Humber (2.3% up from 0.84%) and lowest in South East (0.69% up from 0.29%) and East of England (0.69% up from 0.30%);
Since the last REACT report in early October, the virus has been doubling every 24 days;
Prevalence increased across all age groups; and
The epidemic has progressed from specific at-risk groups to a more generalised pattern of transmission.
Me: The end of Oct jump is what I think tipped the govt into lockdown.
