Figure 2From: Screen more or screen more often? Using mathematical models to inform syphilis control strategies Model-projected annual rates of reported infectious syphilis. Results are based on 1000 realizations of each intervention scenario and are presented as mean values with corresponding 95% uncertainty bounds. Prior to 2011, all scenarios included annual screening only, with the specified interventions implemented at the start of 2011 (indicated by a dashed line).Back to article page
