Over 900 patients with Covid-19 are in Irish hospitals for the first time since mid-April, the total is now 44% higher than two weeks ago.
Some 906 patients with the virus are in hospital, while latest estimates suggest that around half of admissions due to Covid are because of the virus.
From the end of May to July 4, the number of patients with Covid-19 in hospitals in Ireland increased from 198 to 885 with the numbers still rising.
The Irish Nurses and Midwives Organisation has called for additional public health measures due to the impact rising Covid cases are having in hospitals.
INMO President, Karen McGowan commented: "These include the reintroduction of immediate Covid screening upon arrival of patients to EDs, strengthening advice around mask wearing, a second booster for healthcare workers and improved ventilation in healthcare settings.
"The rate at which we are seeing infections rise in our hospitals is extremely worrying. From the 29th of May 2022 to 4th July 2022, we have seen Covid hospitalisations increase from 198 to 885, a 347% increase," she added.
