Heath Minister Robin Swann has said it would be unfair to point the finger of blame at anyone following the chaotic scenes outside several hospital A&Es on Tuesday.
At one point 17 ambulances with patients were lined up outside Antrim Area Hospital, while inside 43 more patients were waiting for an emergency bed.
A further 21 were waiting at the Causeway Hospital yesterday morning.
A leading public health expert has said Mr Swann should resign over Northern Ireland s response to the pandemic.
Belfast-born Dr Gabriel Scally said that if it was up to him, he would change the team .
The Northern Trust explained yesterday that there were no waiting ambulances outside Antrim Area Hospital, but it remained under severe pressure .
