Cost of 80%, 90%, and 100% edge removal early in the outbreak.

<p>The expected costs are shown for a disease with high perceived risk (<i>κ</i> = 1.0) and interventions with 80%, 90%, and 100% edge removal all beginning after 10 cases of the disease. The cost coefficient for intervention (<i>c</i>_<i>I</i>) was 0.05<i>c</i>_<i>D</i>. The most cost-effective intervention for each value of <i>c</i>_<i>S</i> is marked with a star (*). In cases where the pairwise difference in expected cost between strategies was not statistically significant with a permutation test, all least-cost strategies are marked with dots (⋅). For <i>c</i>_<i>S</i> ≤ 0.2<i>c</i>_<i>D</i>, 90% edge removal was significantly less costly than either 80% or 100% edge removal. For <i>c</i>_<i>S</i> ≥ 0.4<i>c</i>_<i>D</i>, 100% edge removal was the most cost-effective intervention level. Nevertheless, 90% edge removal was still less costly than intervention later in the outbreak.
