The “data security incident” began Thursday at facilities operated by Prospect Medical Holdings, which is based in California and has hospitals and clinics there and in Texas, Connecticut, Rhode Island and Pennsylvania.

“Waterbury Hospital is following downtime procedures, including the use of paper records, until the situation is resolved,” spokeswoman Lauresha Xhihani, said in a statement.
