Lake County Health Department and Community Health Center

Lake County Health Department and Community Health Center (LCHD/CHC) operates as a combined public health agency and community health center. It serves the residents of Lake County, delivering public health functions that include the investigation of reportable communicable diseases and outbreak clusters. The organization also provides direct clinical services through its community health center component, offering primary care and preventive care to the local population. A central element of its public health mission is the Communicable Disease outreach program, which handles case investigation, contact tracing, and related outreach activities. Through these combined efforts, LCHD/CHC aims to protect and improve the health of the community it serves.

The organization's headquarters is located in the United States of America, indicating its domestic scope and jurisdictional authority. As a local health department, LCHD/CHC operates under state and federal public health regulations that govern disease reporting and health protection activities. Its dual designation as both a health department and a community health center sets it apart from entities that focus exclusively on regulatory oversight or solely on clinical care. This structure allows the organization to integrate population‑level health initiatives with direct patient services within a single administrative framework.

In March 2023, an unauthorized actor gained access to an employee email account at LCHD/CHC, potentially exposing partially de‑identified personal and medical information of residents involved in the Communicable Disease outreach program. The compromised data included names, addresses, contact details, medical record numbers, lab results, dates of birth, and treatment information. After discovering the breach, the organization worked with Microsoft to secure the affected account and subsequently implemented additional cybersecurity safeguards and staff training to reduce future risks. This episode underscores the sensitivity of the health data managed by LCHD/CHC and its response to cybersecurity challenges in a public health setting.
