We trace the cluster through Mono County Public Health statements, walk through the unusual exposure profile (two of three victims had no mice in their homes, but all three had mice in their workplaces), and pull up the 2012 Yosemite Curry Village precedent for what happens when seasonal architecture and deer mouse habitat overlap. We close with the climate question: a deer-mouse population boom in the Sierra echoes the conditions that triggered the original 1993 Four Corners outbreak.
