Management are thanking the public for their understanding.
Mullingar's Regional Hospital's adult emergency department is busy again today.
Teams are working to manage the adult in-patient and Covid-19 bed capacity, together with scheduled care.
Management are asking people to consider their options before visiting the ED.
If you do attend but are not triaged as seriously ill, you may need to wait for a long period to be seen.
Those who require urgent care will be prioritised.
