Analysis II results showing the relationship between net reproduction number (Rn) at the time of the switch and time until OPV2-related viruses in different reversion stages can establish circulation (i.e., time until Rn becomes greater than 1) in a hypothetical population (see TableĀ 1) The shaded areas show the duration of indigenous circulation of OPV2-related viruses following the switch, which continues indefinitely if cVDPV2s emerge indigenously in the absence of an outbreak response. a Baseline R0 for WPV1 equals 13. b Baseline R0 for WPV1 equals 10
