Pennsylvania is firing a company that performed COVID-19 contact tracing and exposed the private medical information of tens of thousands of residents, state officials said Thursday.

Employees of Insight Global used unauthorized Google accounts — readily viewable online — to store names, phone numbers, email addresses, COVID-19 exposure status, sexual orientations and other information about residents who had been reached for contact tracing. The company’s contract with the state required it safeguard data.

The Department of Health said last month that at least 72,000 people were impacted. The state had planned to drop Insight Global once its contract expires at the end of the July, but the Health Department said Thursday it will terminate the contract early, on June 19.

The department said that it was taking action “after more fully evaluating the circumstances” of the security lapse.

Insight Global is required to notify impacted people, and the Health Department said those notifications would begin next week. The department said the state’s contact tracing operation would continue with a new vendor.

“We are working to make sure that there is not a break in continuity in our contact tracing services as we transition out of the Insight Global contract and into our next contract,” Acting Health Secretary Alison Beam said Thursday.
