For the 23rd day in a row, no new Covid 19 deaths were recorded in Northern Ireland.
Last week's death toll was 36% higher than the previous week, though deaths are a lagging indicator and can continue to rise weeks after new infections drop.
And, in some good news, there have been no new deaths reported to the HPSC again today.
Of the cases announced this evening, they are located in Wexford (11), Kildare (10), Dublin (6), Donegal (5) with the remaining 18 spread across Carlow, Cork, Limerick, Louth, Meath, Offaly, Sligo, Tipperary and Wicklow.
The letter, penned by acting chief medical officer Dr Ronan Glynn, advised the Government to halt the planned progression to Phase Four of the country's reopening on August 10th. "However, NPHET's priority must be to control the spread of this virus in our communities and to protect the progress that we have achieved to date". 'Covid-19 is an extremely contagious virus and we have seen a significant increase in its spread across multiple counties over recent days.
"That's why, on the advice of NPHET, we'll be recommending to Cabinet that we take a very cautious approach for the next couple of weeks".
