Health officials say the area of greatest concern is now the number of cases in residential institutions.
167 deaths have been confirmed among covid-19 patients at nursing homes.
HSE Chief Clinical Officer Dr Colm Henry says expert doctors and more resources are being sent to help.
Some of them pertain to infection prevention and control, through the provision of PPE.
"There's more focussed support given to some nurses, the provision of staff in some cases HSE staff, in some cases consultant geriatricians advising on clinical care.
"This is if they have higher numbers of people who are ill, to make sure they have the skills and the input necessary to provide with them with any care needs that an older, frailer population might have."
