Temporal transmission dynamics of COVID-19 with a baseline transmission reduction and implementation of strict measures. The temporal dynamics of the numbers of newly infected people, severe cases, and cumulative deaths are shown. In the simulation, we assumed that transmission was reduced by 40% (A, C) or 20% (B, D) as baseline nonpharmaceutical intervention restrictions. The vaccination coverage (lines in three colors) and the vaccine efficacy (panels A and B for very effective vaccines; and panels C and D for effective vaccines) were subject to change. Strict measures reducing transmissions by 70% were implemented for 60 days when severe cases surpassed 2000.
