The Lake County Health Department announced two data breaches, one of which occurred in 2019, that compromised the data of almost 25,000 people.
Jefferson McMillan-Wilhoit, the Chief Health Informatics and Technology Officer for the Lake County Health Department, said the first breach was discovered on July 22, 2019.
McMillan-Wilhoit told the Chicago Tribune that the first breach, which was disclosed earlier this month, occurred after an unencrypted email was sent to an internal employee’s personal email address.
The spreadsheet consisted of medical records requests from December 2016 to June 2019 made through a third-party vendor who provides release of information services.
The information in the spreadsheet consisted of numbers and dates relevant only to the vendor along with a name.
