A surge in flu and covid cases has increased pressure on the country's hospital emergency departments.
The HSE is appealing to the public to consider using alternative facilities depending on the illness.
It says 13 local injury units across the country are available for treating fractures.
HSE's Chief Clincal Officer, Colm Henry, says flu cases are expected to peak in the next two weeks.
"Flu cases are up 92% in terms of Emergency Departments (ED) attendances at emergency departments from last week and COVID-19 are up 77%.
"What we have seen compared to last year is a bit of a lag. So the peak in flu cases last year came a couple of weeks earlier.
"We're expecting the flu cases to peak in the next week or two."
