HSE chief executive Paul Reid said that Ireland is entering a new phase in relation to the coronavirus.
In a posting on social media, he said he fully supported HSE hospitals who have to make decisions on restricting visitors based on clinical risk, patient and public safety.
Yesterday, the Chief Medical Officer at the Department of Health Dr Tony Holohan said these general measures were not needed and should be lifted.

An unprecedented national effort will be required to respond to the public health crisis arising from the Covid-19 outbreak, according to the Government, unions and employers, who say they will work closely with stakeholders across society in response to the situation.
In a statement, the social partners call on both employees and the self-employed to abide by public health advice regarding appropriate self-isolation.
They also say that in doing so, employees would have their income protected to the greatest extent possible, following the agreement on measures to enhance state illness payments.
Employers are being urged to support the national health objectives by continuing to pay employees who cannot be in work due the virus or the need to self-isolate the difference between illness benefit and their normal take home pay.
However the Government, unions and employers say they accept for some companies this will not be possible.
The bodies also say they recognise that some firms will face severe business and cash flow pressures and liquidity measures to help them have been announced.
Trinity College Dublin defends decision to cancel lectures
Trinity College Dublin has defended its decision to go further than current Department of Health advice and cancel all face-to-face lectures.
It has emerged also that the curtailing of teaching at the college is wider than originally anticipated with some departments cancelling not just lecturers but all teaching, including to small groups of student in tutorials.
Yesterday the university announced that it was cancelling all lectures, and closing all tourist attractions including the Book of Kells exhibition.
The Trinity College decision to cancel lectures, and some smaller classes, goes beyond current Department of Health advice, which is that schools and colleges should remain open and that teaching should continue.
Asked about this a spokesperson said the college had to follow "the best advice that is available to us".
He said Trinity College was listening to the Health Service Executive, and also to the World Health Organization, as well as to experts from within its own academic staff.
"We have informed the HSE, but we have to do what is best for us, and this is what we think is best", the spokesperson said.
He pointed out that 55 universities worldwide have done similar, including universities where no cases of the virus have been detected.
One case of Covid-19 was detected last week at the college's Biomedical Sciences Institute. This is where Trinity College's immunology research centre is located.
The Trinity spokesperson said the decision to cancel face-to-face lectures and other teaching also took into account the fact that the college has a population that is hugely international, with a high level of staff, students, and visitors coming from abroad.
The college plans to deliver lectures online.
Meanwhile, the Government has appealed to employers for help while it deals with the challenges faced by people who have to stay at home because of the Covid-19 virus.
Minister for Finance Paschal Donohoe called on all employers to play their part in what he said will be a national response to the national public health crisis we face.
Speaking at a press conference he said it was critical individuals follow public health advice in terms of self-isolating, but that the Government understands decisions can have consequences for businesses.
He called on employers to continue to pay employees who may need to go into self-isolation, and that funds will be available to help.
His colleague, Minister for Business Heather Humphreys, said there was cooperation from opposition parties, trade unions and business representative bodies in terms of the supports being given to businesses.
She referred to the €200m Strategic Banking Corporation of Ireland Working Capital scheme for businesses where they can avail of loans of up to €1.5m if they are impacted by Covid-19.
Ms Humphreys also said there is a rescue and restructuring scheme available as part of the €200m Enterprise Ireland fund, and local enterprise offices can provide vouchers from €2,500 - €10,000 to help with planning for businesses.
Ms Humphreys also urged people not to panic buy over Covid-19 fears.
She said she had met retailers and grocery distributors and that she was very satisfied there is a significant supply chain.
She said she had previously had these meetings in terms of a no-deal Brexit and that she was very happy there were plans in place. The minister said people should not panic buy because "that in itself causes shortages".
Around 80% of cases of Covid-19 will be a mild to moderate illness, close to 14% have severe disease and around 6% are critical.
Generally, you need to be 15 minutes or more in the vicinity of an infected person, within 1-2 metres, to be considered at-risk or a close contact.
The latest figures show that more than 66,500 people have recovered from Covid-19.
