(β, l) parameter space when R0 < 1 obtained from the uncertainty analysis (black dots). The deterministic (β, l) level curve when R0 = 1 is shown in by the dotted white line. All other parameters in equation 1 were fixed to their baseline values (Table 1). l = 0 denotes perfect isolation; l = 1 denotes no isolation.

1At the time this work was carried out, Dr. Castillo-Chavez was on sabbatical at Los Alamos National Laboratory and faculty of Cornell University.

2Recall that l = 0 corresponds to complete isolation, whereas l = 1 means no effective isolation occurs. Hence, a decrease in l means an increase in the effective isolation of the infected persons.
