The vast majority of track and trace cases are being successfully detected, Northern Ireland’s health minister said.
In the past week, a total of 4,450 cases have been sent to test, trace and protect and 4,023 cases were successfully detected, Robin Swann added.
He told the Assembly there were a further 9,267 contacts from these cases and that 99% of those were contacted.
He said: “People often look at the criticism that is happening at the one in Westminster and try to align those aspersions onto our own one.”
He was responding to a question from Daniel McCrossan of the SDLP.
Mr McCrossan said other countries had more rigorous systems in place.
Former Ulster Unionist leader Mike Nesbitt asked the minister about a pilot testing scheme taking place in Liverpool.
Mr Swann said he thought it would be useful.
He was also asked about distribution of this year’s flu vaccine, which has been delayed for some recipients.
“It is proceeding at pace. We have increased delivery of flu vaccines,” he said.
Normally a first delivery covers the first three months of the flu season then a second fills in any gaps.
This year the first batch was used up within 26 days and most people invited took it up.
The second arrives in the coming weeks.
Mr Swann said: “The system outstripped the supply that we have.
“When it comes to the availability of a Covid vaccine we know the systems that worked very efficiently.”
One GP sent out 500 letters for flu jabs and 499 of those attended.
The minister said: “This is something that comes as a criticism but has delivered far in excess of our expectations.”
Finance Minister Conor Murphy also took questions at the Assembly on Tuesday.
SDLP Assembly member Patsy McGlone said around 2,170 applications have been made to a Covid business support scheme, but questioned how many of those applicants have received money.
Mr Murphy said “there is more than one set of data required” but admitted payouts had not been as fast as he had hoped.
Around 300 applications that have been assessed as not meeting the criteria in relation to the scheme managed by the Land and Property Service.
