This June, health officials in Riverside County confirmed the season's first positive samples in the Coachella Valley region, setting in motion the familiar but urgent work of containment. The virus asks little of most people it touches, yet for the vulnerable it can reach into the nervous system with devastating consequence — a reminder that the smallest creatures can carry the heaviest burdens.

Households face increased healthcare costs if infected, potential travel disruptions to affected regions, higher demand for mosquito repellents and protective measures, and anxiety-related economic behavior changes.
