One of the members of NPHET has registered his "concern" over a number of things as Ireland's Covid-19 case tally rose above 2,000 once more.
In the last 24 hours Ireland has recorded 2,074 new cases of Covid-19.
As of 8am on Saturday morning, there were 229 patients in hospital fighting the deadly virus.
Of those in hospital, 43 were in intensive care.
The latest figures were released by the National Public Health Emergency Team - and Professor Philip Nolan, a member of NPHET, has posted an interesting thread on social media this evening in the aftermath.
Professor Nolan said: "This is very different from January. Vaccination is preventing an enormous number of transmissions, and is reducing the severity of disease in the minority who become infected despite vaccination. Nonetheless, the rising incidence is a real concern.
"Incidence is rising across all age groups, and in all parts of the country. We are starting to see incidence rise, albeit from very low levels, in those aged 65 and older.
"The numbers in hospital and ICU are increasing"
However, there was one big stat that should be causing worry.
Professor Nolan explained: "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..
"This is not sustainable.
"Vaccines work, but we need to continue to be cautious with this virus, and to protect ourselves and each other with some basic public health measures. We’re tired, and we wish it was all over, but it’s not. Look after each other."
