California Hospital Exposes 65,000 Patient Records in Major Security Breach

City Health reported a security breach on April 14, 2026 that exposed medical records for 65,000 patients—90 percent of all healthcare breaches reported to federal authorities between mid-April and May. Three smaller breaches at other hospitals and clinics affected roughly 7,768 more patients. When large healthcare systems experience security failures, patient data across entire organizations becomes vulnerable all at once.
