Comment by Sim18 on What made the UK COVID-19 case count drop? · 2021-08-03T11:17:59.586Z · LW · GW

In the UK the Delta variant seems to have followed a similar curve to India: sharp increase followed by sharp fall. The Indian peak was around the begining of May, the UK around the 20th of July. ONS estmates 91.9% of adult UK population have antibodies (both figures are current not at start of curve). In India it's about 67% of population has antibodies. It is not known why the steep fall in cases happened in India. If the patterns are as similar as they appear we can, perhaps, rule out schools and other factors not common to the 2 countries.
