CDC surveillance excludes homeless people

The CDC’s BioSense platform ingests near‑real‑time data from 7,200 hospitals, clinics, and emergency departments, but the program reportedly collects no data from homeless shelters or clinics, leaving an estimated ~800,000 people outside national syndromic surveillance. That blind spot coincides with rising mass overdose events and creates a gap in early detection of infectious or toxic events among a high‑risk population. — A national surveillance system that omits homeless populations undermines public‑health equity and biodefense readiness and should reshape policy debates on data collection mandates, resource allocation, and emergency planning.
