Investigation notes
The City of Houston Health Department is a government-operated public health agency responsible for providing essential medical services, disease surveillance, and community health programs. As a healthcare provider and public health entity, the department maintains sensitive records including patient medical histories, immunization logs, and personal identification data required for clinical services. This security incident was officially reported to the Texas Attorney General in 2026, confirming that unauthorized access to their systems occurred. If you received a formal data breach notification letter, it indicates that your personal or health-related information may have been compromised during this event. We recommend reviewing the letter carefully to understand the specific scope of the exposure and the identity monitoring services being offered to you.
What our attorneys examine
A cyberattack does not excuse a company from protecting the information it holds. We look at whether City of Houston Health Department used reasonable security, how long it kept the data, and how quickly it told the people affected. Those questions decide whether a class action or individual claim is possible. Read more on how ransomware lawsuits work, or browse other incident files in Texas.

Attorney advertising. An incident file reflects a public regulator filing and our review of it; it does not mean a lawsuit has been filed or that the company did anything unlawful. Submitting a review request does not create an attorney-client relationship.
