Six more people with COVID-19 have died in the Republic.
One death that had previously been classed as COVID-related has been denotified, so the number of deaths now stands at 1,743.
A further 23 cases of the virus have also been confirmed, bringing the total number of cases here to 25,565.
According to Prof Philip Nolan, chair of the National Public Health Emergency Team's (NPHET) Irish Epidemiological Modelling Advisory Group, "we are seeing an increase in the number of reported cases over the last two weeks and the R-number is now at or above 1".
The R-number represents how many people the average person with the virus is likely to infect. The higher the number, the faster the disease spreads. Ireland had managed to keep the R-number below 1 since April.
"There is an immediate need for all of us to take care and caution in our decisions and actions," Prof Nolan insisted.
Meanwhile, according to the Department of Health's deputy chief medical officer, Dr Ronan Glynn, fifteen of today's confirmed cases are related to travel.
"NPHET today reiterates that all non-essential travel overseas should be avoided.
"In addition, 77% of cases reported today are under 25 years of age. COVID-19 is extremely infectious and none of us are immune. It is important that we all continue to follow public health advice and risk assess our actions," he said.
Dr Glynn added that NPHET has also recommended that all visitors to healthcare settings, including hospitals, GP practices and pharmacies, should wear face coverings.
