bringing the total number of cases in the Republic to 17,607.
An additional 28 patients diagnosed with Covid-19 in Ireland have died today.
Speaking at the press briefing, Dr Tony Holohan, Chief Medical Officer at the Department of Health said the number of confirmed cases today is reflective of an ambitious programme of testing in nursing homes.
The Health Protection Surveillance Centre revealed that as of midnight on Tuesday, Dublin had the highest number of cases at 8,216 followed by Cork with 1,087 cases.
"Covid-19 is a highly infectious disease.
"Modelling data shows us that the reproduction number remains below 1.0 and that we have achieved great progress through the action of staying apart," Dr Holohan stated.
"In order to continue protecting ourselves, our vulnerable groups and our healthcare workers, we must continue to practice physical distancing, respiratory etiquette and regular hand washing.
"These basic steps, if done by all, will save many lives," he continued.
Dr Ronan Glynn, Deputy Chief Medical Officer, Department of Health, said:
"Today, the World Health Organisation Regional Director for Europe noted that up to half of those who have died of Covid-19 across Europe were living in residential care settings.
"Ireland continues to closely examine mortality so that we can understand it and do everything in our power to prevent it.
"We are now using our increased testing capacity to focus on staff and residents so that we can learn in real-time about this virus and take actions informed by that evidence."
Professor Philip Nolan, Chair of NPHET Epidemiological Modelling Advisory Group stated that as a result of the public's cooperation with government and HSE directives, the transmission of the virus is effectively suppressed
"For the population at large, the growth rate is at zero and the transmission of the virus is effectively suppressed.
"Our R number is between 0.5 and 0.8. This success emphasises how vital it is to remain vigilant in our behaviours.
"If the R number moves above one, we are no longer in control of the disease," he explained.
So far, there have now been 794 Covid-19 related deaths in Ireland. The median age of deaths in Ireland is 83.
