Power-law distribution of the number of virus victims is derived from heterogenity across spreaders. What makes worse is the convex cost with respect to the number of victims. Similarly to taking higher-order moments under power-law distribution, the expected cost can become surprisingly high even if the number is truncated at some population. Policy for cutting the tail by specifically focusing on the superspreaders should be encouraged.]]>
