'Close contact transmission'
Dr Ronan Glynn, Deputy Chief Medical Officer, said: "It is a very welcome development to see new visitation guidance for nursing homes coming into effect from today.
"As we begin to experience the benefits of vaccination, it is a reminder of what we are collectively working towards, a vaccination rollout that, along with our other protective measures, will end this pandemic.
"People have worked exceptionally hard over the past three months to reduce transmission in our communities. We have shown time and again that we can act collectively to protect one another. Please keep this going over the coming weeks."
While Professor Philip Nolan, Chair of the NPHET Irish Epidemiological Modelling Advisory Group, said: "For the week of the 7th-13th of March, 60% of disease incidence is taking place through close contact transmission and 24% in the community.
"59% of transmissions are occurring in households. Outside of the household, almost half of transmissions are occurring in social gatherings and the workplace."
And Dr Cillian de Gascun, director of the National Virus Reference Laboratory, said: "The B117 variant, Ireland's most dominant variant of COVID-19 accounts for more than 90% of our cases and is extremely transmissible.
"Public health advice aims to limit the opportunities this virus has to spread, and it should be noted that B117 does not need much opportunity to do so.
"The most effective way to stop the spread of this variant and all variants of COVID-19 is to limit your social contacts and follow public health advice".
