A fifth person has died in Northern Ireland after being diagnosed with Covid-19.
Stormont's Department of Health said the patient, who was in her 80s, died in Antrim Hospital.
A fourth death today was also confirmed as Covid-19 related.
Earlier, First Minister Arlene Foster believes that sweeping new restrictions in the UK will last more than three weeks.
She said if she was a "betting person" she would think the measures will continue beyond Easter.
People must remain at home except for shopping for basic necessities, exercise, any medical need and travelling to and from essential work, British Prime Minister Boris Johnson said.
Shops selling non-essential items were told to shut and gatherings in public of more than two people who do not live together are banned.
Mrs Foster told the BBC's Good Morning Ulster programme matters would need to be reviewed after three weeks.
Police will have powers to enforce the rules using fines and separating gatherings.
Health Minister Robin Swann also announced today that Covid-19 testing would be expanded to 1,100 per day.
More than 600 tests are already being carried out daily in the regional virus laboratory in Belfast. By early next week that number will increase to 900.
Two other testing centres will later begin operating, bringing the total to more than 1,100, Mr Swann said.
