Seven detainees in ICE custody at the Florence Service Processing Center in Arizona have been confirmed with measles. An unspecified number of additional detainees at the Eloy Detention Center and Central Arizona Florence Correctional Complex were placed under quarantine for possible measles exposure. Arizona Democratic representatives Greg Stanton, Yassamin Ansari, and Adelita Grijalva, along with Senators Ruben Gallego and Mark Kelly, sent a letter to the Department of Homeland Security demanding details about quarantine protocols, medical staffing, and whether detainees had access to legal meetings and court hearings during the lockdown. This is the second measles outbreak reported in Arizona ICE facilities in 2026, with three cases reported in February.
