Another case of coronavirus has been diagnosed in Northern Ireland, taking the total to four.
The latest person who has tested positive is an adult who recently returned from Italy - their diagnosis has been linked to a previous case.
Northern Ireland's chief medical officer said he expected more cases "in the days and weeks ahead".
Five more cases were also confirmed in the Republic on Friday evening, taking the total on the island to 22.
The test sample from the latest case in Northern Ireland will be sent to a laboratory in England for verification.
"Northern Ireland remains in the containment phase and it is important to emphasise that," said chief medical officer Dr Michael McBride.
The first person to be diagnosed in Northern Ireland - which was confirmed last week - was a woman who had returned from northern Italy, the area at the centre of the outbreak in Europe.
That was followed by two more cases that were confirmed on Wednesday - one of those was a postgraduate student at Queen's University in Belfast.
A group of students at the university were asked to self-isolate as a precautionary measure as a result of that case.
The latest case is not connected to the university, BBC News NI understands.
Drive-through testing facilities are expected to be operational at hospitals across Northern Ireland within the next week.
One is already in place at Antrim Area Hospital.
