  1. Generalized linear models (GLM) were used for estimating the IRRs of seven Respiratory infectious diseases. Phase 1: year 2020, Phase 2: year 2021, and the reference period is 2020. The IRR of Model 1 was not adjusted; The IRR of Model 2 was adjusted by the School closing, Workplace closing, Cancel public events, Restrictions on gatherings, Close public transport, Stay at home, Restrictions on internal movement, and International travel controls. All p-values are two-sided and not adjusted for multiple comparisons
