Ninety-four people with Covid-19 are being treated at Letterkenny University Hospital, according to the latest HSE data.
The hospital had a record high figure of 103 Covid-19 cases on Tuesday.
Six patients with the virus are currently recorded in ICU at LUH.
The pressure on bed availability continues, with zero general care beds available and just one critical care bed open last night.
In response to demand, Letterkenny University Hospital has deferred all but very urgent and time-critical inpatient and day surgery until January 19th.
Outpatient clinics will also be restricted however some of these will take place virtually unless it is absolutely necessary for patients to be seen.
The deferrals will be kept under review.
Patients will be notified directly if their appointment or procedure is being deferred.
