Nursing Homes Ireland says staffing remains the biggest issue in the fight against Covid-19.
It says 40 of the country's 570 residential facilities currently have clusters of the virus.
A nursing home in Galway appealed for help earlier this week folowing a major outbreak.
25 of the 27 residents at the Nightingale Nursing Home were confirmed to have Covid-19 and one person has died.
CEO of Nursing Homes Ireland, Tadhg Daly, says the HSE needs to act swiftly when outbreaks occur.
