FIGURE 4.

Evolution of annual TB cases over 10 years according to virtual experiments. Four scenarios are considered: current situation (control), in green; a 2-year health care reform, in blue; a 5-year reform, in orange; and a permanent reform, in red. The health care reform would exclude adult undocumented immigrants from the public health system and would consequently increase their diagnosis delay. We assumed the current 33-day period for non-reform cases and a 50-day period for reform cases.
