The covered entity (CE), Colorado Allergy and Asthma Centers, reported that an employee was the victim of an email phishing scheme that affected the protected health information (PHI) of 791 individuals. The PHI involved included names, addresses, dates of birth, Social Security numbers, diagnoses, and other treatment information. The CE notified HHS, affected individuals, the media, and provided substitute notice. In response to the breach, the CE implemented additional administrative and technical safeguards and retrained its employees on email security.
