Figure 6.
Differences in the average monthly incidence of eight respiratory infectious diseases in the emergency response stage (January to April 2020) and the routine response stage (May to December 2020) in Zhejiang Province. Note: The pink lines reflect differences in 95% confidence interval values. The pink dots indicate the median points. Changes = (x2 − x1)/x1 × 100%, x1: average monthly incidence in pre-COVID-19 period, x2: average monthly incidence in during COVID-19 period. The p-values were computed using two proportional tests. For the emergency or routine response stages, the p-values for the emergency versus the routine response stages were computed using two ratio tests.
