Fig. 1 The weekly event volume by event type. The upper right line graphs describe the per member per weekly occurrence of qualifying diagnostic codes on identifiable Medicare claims. COVID-19 (red), influenza (green), and respiratory infection codes (blue) are featured. The bottom right figures show the Excess Deaths (Red) and Observed Deaths (Blue) from which excess deaths are learned in the CDC excess mortality model. The upper left region describes the NEMSIS series with cardiac arrest after EMS arrival (Red), cardiac arrest prior (Brown), total calls (Green), calls without cardiac arrest (Blue) and calls with arrests (Purple). The lower left shows the all-cause mortality multiple cause of death certificate volumes (Red) and volumes where the primary (Green) and secondary causes of death (Green) were COVID-19. The x-axis is the study week, and the y-axis is the volume for all figures.
