Figure 1. Epidemiologic modeling of the SARS-CoV-2 Omicron BA.2 wave dynamics, France. Simplified flowchart of the Covidsim framework. Persons can move between several compartments in the general population (in yellow or pink depending on the infection status), in CCUs in blue and removed from the system, either because of their immunity to BA.2 or of death (in gray). Part of the general population is vaccinated (green dashed line), which affects epidemiologic dynamics in 3 ways (illustrated with the shields), namely reduced infectivity, reduced virulence, and reduced risk for infection. CCU, critical care unit.
