People in the Northern Sound region are advised to seek alternatives to Cavan's ED amid a "significant increase in the number of covid positive patients" at the hospital.
Cavan General Hospital is currently experiencing high levels of attendances and admissions.
The hospital has also seen a "significant increase in the number of Covid positive patients presenting to and admitted to the hospital, which is resulting in an increase in overall admissions".
Last night, there were 36 confirmed covid cases in Cavan General Hospital, two of whom are in ICU.
All patients are advised of delays and limited bed capacity at present.
A hospital spokesperson says "if alternatives to an Emergency Department referral are available, these should be explored as a priority".
