The Department of Health has been notified of 1,189 new cases of Covid-19.

There are 95 people in hospital who have tested positive for coronavirus, down one since yesterday, of whom 23 are in ICU, a rise of one compared to yesterday.

There were 1,430 positive cases reported in Northern Ireland today and no further deaths. A decision on easing most restrictions there next week has been delayed by Stormont ministers.

Deputy Chief Medical Officer, Dr Ronan Glynn, said: "The Delta variant is now dominant across the EU and, in recent weeks, we have noticed a sharp increase in the level of travel-related cases of Covid-19.

"Only those who are fully vaccinated or who have recovered from Covid-19 in the last 180 days should be considering international travel at this time.

"If you have recently returned to Ireland and have any symptoms of Covid-19, including fever, cough, headache, sore throat or a blocked or runny nose then please self-isolate and get tested without delay."

What is 'vaccine breakthrough' and 'vaccine escape'?

Meanwhile Tánaiste Leo Varadkar has said every effort is being made to ensure new regulations for indoor hospitality are published no later than this weekend.

Speaking on RTÉ's News at One, Mr Varadkar said the regulations are not straightforward, but are not "unduly complicated".

Also today, HSE Chief Clinical Officer Dr Colm Henry said that even for those who are fully vaccinated, Delta poses a risk.

"The harm is pushing towards older more vulnerable people all the time, even those who are fully vaccinated," he warned.

He explained that if there is a high enough level of cases of the coronavirus in the community, vaccinated individuals will be affected and the "flood walls breached".

Professor Philip Nolan, chair of the National Public Health Emergency Team's modelling advisory group, expanded on this on Twitter.

He noted: "We are starting to see cases in those aged 65 years and older, a group where a few weeks back the infection was almost eliminated."

The rate of growth is "very concerning", he said, about 6% per day and warned: "If this continues, case numbers will double every 12 days, building up a very large force of infection and burden of disease.

"We need to be exceptionally careful in the coming weeks."

Prof Nolan added: "This will translate into an as-yet-unknown level of severe disease and mortality over the next two to four weeks.

"We know from models and international data that it will be much less than before vaccination, but it remains uncertain and dangerous."

It has also emerged that more than 17,000 Digital Covid Certificates had to be re-issued in recent days because of a missing síneadh fada in people's names.

Conradh na Gaeilge had complained about a number of misspellings of names in Irish on some of the more than two million certificates issued over the past week.

Elsewhere, the EU has said 200 million Europeans have been fully vaccinated, more than half of the adult population but still short of a 70% target it had set for the summer.

Commission spokeswoman Dana Spinant told reporters that based on the latest data of the European Centre for Disease Control "54.7% of the adult population is fully vaccinated with either two doses or one dose in the case of the Johnson and Johnson vaccine".
