CNN —A children’s hospital in Chicago is still trying to restore its computer systems nearly a week after a cybersecurity incident prompted it to shut down its network. Lurie Children’s Hospital says the outage has affected email, phones and some other electronic systems. The hospital remains operational, but it said the outage has made scheduling, accessing medical records and prescription history difficult for patients and staff. Lurie has not given any details on the nature of the cybersecurity incident or whether a ransom has been demanded for full access to its systems. Late last week, Lurie established a call center for clients who are unable to reach the hospital through their regular phone number or electronic messaging systems.
