Figure 3. Percentages of different Ct value categories
Before comparing Ct value trends and Rt trends, we compared Rt trends
with number of new cases. The number of new cases increased at a point
in which Rt rose substantially. By period, there was a marked increase
of new cases when Rt rose significantly during the first and second
waves, but during the third and fourth waves, Rt remained largely stable
despite the number of new cases surging (Figure 4).
