65% of the population is fully vaccinated against the virus.
As of midnight on Tuesday 20 July, the Department of Health has been notified of 1,378 new cases of Covid-19 as incidence rates in every county have increased over the past week.
Of the 1,378 cases, 96 are in hospital and 22 are in intensive care units.
According to the Department, daily case numbers may change due to future data review, validation and update.
75% of the population have now received at least one dose of the Covid-19 vaccine, meanwhile, 65% are fully vaccinated.
In a statement following the case numbers on Wednesday, the Department of Health said: "We know that COVID-19 vaccines are extraordinarily effective at reducing each person’s individual risk of hospitalisation or severe disease. The Delta variant does not change this.
"However, this variant is much more transmissible than what we have been dealing with previously and, as such, the challenge remains to protect as many people through vaccination as quickly as possible, across all age groups.
"Vaccines along with the core public health advice remain our pathway out of this pandemic – please avail of the opportunity to get protected through vaccination when it is offered to you.
"The basic measures remain as important and effective now as at any point in the pandemic and remember no one measure is sufficient by itself."
