The Department of Health has been notified of 2,074 new cases of Covid-19.
The number of people in intensive care units is 43, unchanged from yesterday.
There are 229 people being treated for the virus in hospitals.
The incidence of Covid-19 is rising across all age groups and in all parts of the country, according to the Chair of the National Public Health Emergency Team’s Epidemiological Modelling Advisory Group.
In a post on Twitter, Professor Philip Nolan said they are beginning to see an incidence in those aged 65 and older “albeit from very low levels”.
He said while the situation is “very different from January” and vaccination is preventing an enormous number of transmissions and reducing the severity of the disease, but added that the “rising incidence is a real concern”.
Prof Nolan said that on 3 July there were 42 people in hospital with Covid-19 and 14 in ICU, with an average of seven admissions a day, compared to an average of 32 admissions per day currently, which he said is not sustainable.
He said: “The real concern is that there is an underlying established pattern of exponential growth, with cases growing at about 3.7% per day since 19 June, and numbers in hospital growing at a similar rate, 4% per day, since early July.”
