Emergency rooms have reopened at two Hackensack Meridian hospitals after a ransomware attack.

A hospital spokesperson says their Mountainside and Pascack Valley Medical centers are not seeing significant delays as they work to get back to normal.

The ransomware attack forced the hospitals to send patients away from their emergency rooms over Thanksgiving weekend.

“As we work to bring our systems back online, each hospital will continue to evaluate its ability to safely care for critically ill patients in its Emergency Room. Because this is rapidly changing and dependent upon a number of factors, our status may continue to change as the situation changes,” a spokesperson for Mountainside Hospital wrote in a statement.

The hospitals are part of Ardent Health Services.

Capital Health also experienced some network outages in what is believed to be a cybersecurity incident.

“We continue to care for patients in both hospitals, including our Emergency Rooms, in our practices, and at all other locations under established protocols for system downtimes where necessary. We are prioritizing safe patient care, while working to restore the network and address the impact of this disruption,” a spokesperson wrote in a statement.

Law enforcement officials are investigating the cyber incidents.
