People in Northern Ireland cannot relax their guard over the next fortnight when a surge of coronavirus cases is anticipated, the first and deputy first ministers have warned.
They told a remote press conference there had been seven more Covid-19 related deaths in NI.
It brings the total number of NI deaths in the global pandemic to 70.
Arlene Foster later sent prayers and best wishes to Boris Johnson after the PM was moved into intensive care.
On behalf of the Northern Ireland Executive, I send our best wishes to the Prime Minister @BorisJohnson— Arlene Foster #WeWillMeetAgain (@DUPleader) April 6, 2020
Praying for a full and speedy recovery.
The 55-year-old, who was admitted to hospital in London with "persistent (coronavirus) symptoms" on Sunday evening, was transferred when these symptoms "worsened", Downing Street said.
The surge of the virus is expected to arrive in NI between 6 and 20 April.
The Public Health Agency said a further 69 cases of coronavirus had also been confirmed in Northern Ireland, bringing the number of confirmed cases to 1,158.
Meanwhile, the number of coronavirus hospital deaths in the UK reached 5,373 - an increase of 439 in a day, with 51,608 confirmed cases.
There have been 174 coronavirus-linked deaths in the Republic of Ireland, where there are 5,364 confirmed cases.
Arlene Foster and Michelle O'Neill led Monday's daily press conference remotely for the first time, appearing from their homes.
Mrs Foster described the next two weeks as "critical", thanking those who had adhered to guidelines on social distancing.
But she added: "It is essential in this period that we do not relax our guard, especially in the lead-up to and during the Easter period."
Deputy First Minister Michelle O'Neill said the executive would continue to reinforce the message that people must stay at home.
"This is not an Easter week holiday, or a time for people to be relaxing," she added.
"It is a time for people to follow the letter of the law, the advice they have been given to stay at home and try to stop the spread."
The first and deputy first ministers also welcomed the delivery of additional Personal Protective Equipment (PPE) for frontline workers in Northern Ireland.
The first batch of 5.5m pieces of PPE arrived in Belfast on Monday from Great Britain, including 1,320,000 aprons and 307,800 FFP3 respirator masks - which provide the highest level of protection.
Ms O'Neill said the other priority had to be increasing testing for the virus.
"There are plans to bring forward a rapid scale-up of testing, to increase testing of our health and social care workers, to increase testing for people in residential care settings so I think that is a move in the right direction," she added.
The ministers also condemned threats made against Health Minister Robin Swann, after offensive comments were made against him on social media last week.
