Figure 1.

Differences in the average annual incidence of eight respiratory infectious diseases in Shanghai and Zhejiang comparing pre-COVID-19 and COVID-19 periods. Note: The pink lines reflect differences in the 95% confidence interval values. The pink dots indicate the median points. Changes = (x₂ − x₁)/x₁ × 100%, x₁: average annual incidence of respiratory infectious disease in pre-COVID-19 period, x₂: average yearly incidence in during COVID-19 period. The p-values were computed using two proportional tests.
