Chief medical officer Dr Tony Holohan has advised people against planning foreign holidays this summer.
He said the National Public Health Emergency Team (Nphet) are advising against non-essential travel “for the foreseeable future”.
Dr Holohan said it is “not realistic” to expect the summer to be “characterised” by people flying to different countries on holiday.
“I don’t think we’re heading for a summer where millions of people from this part of the word can head to the beaches, other than the beaches in their own localities.”
In response to criticism of Nphet from Ryanair boss Michael O'Leary, Dr Holohan said he had "nothing but admiration" for Mr O'Leary.
However, he dismissed Mr O'Leary's claim that Nphet is pushing “misinformation”.
He said that public health officials must sometimes deliver bad news, however, “overall we stand over the process, the information and the advice we’ve given”.
