Schematics of bifurcation diagrams for different scenarios. a Gives the general patterns expected when there is no intervention; at any non-zero value of the prevalence it will move vertically towards the blue line R0. b Scenario with reduced transmission potential. c Scenario with a small reduction in transmission potential and a saddle-node bifurcation
