Emergency medical teams have been sent to the hospital to make sure it is properly staffed.

In a statement, the RCSI Hospitals group refused to confirm the number of doctors and nurses who have become infected, but said its staff absenteeism rate has increased by almost 7% since January.
The statement read: "Cavan General Hospital has plans in place to manage additional demands due to Covid-19. The Hospital has areas designated for care of patients with Covid-19, patients who are awaiting diagnosis and patients who are not. There is capacity available for all of these patients."
"In January 2020, prior to Covid-19, the absenteeism rate was 5.6%, presently it is 12.2%. The hospital continues to have a number of staff off at present."

Ms Durcan, who is based in Beaumont Hospital in Dublin, told RTE Radio 1's Sean O'Rourke show that medics are keen the hospital is properly staffed over Easter weekend.
"What we have been doing from our group is sending staff to Cavan to make sure that they can be safely staffed over the upcoming number of days," she said.
