This modelling data on COVID-19 in Ireland was presented at the Department of Health press briefing on Thursday 23 April 2020 by Professor Philip Nolan, Chair of NPHET Epidemiological Modelling Advisory Group.
Professor Nolan said:
"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.”
