Health Minister Robin Swann is self-isolating after receiving an exposure notification from the StopCOVID NI app.
An exposure notification from the app means the user has been in close proximity to another user who has tested positive.
Self-isolation is required for 14 days.
Mr Swann will be fulfilling his Ministerial duties from home for the required period.
He will only take a test if he develops one of the symptoms of the coronavirus.
Meanwhile East Antrim MLA John Stewart has tested positive for COVID-19.
He said he felt ‘really unwell’ on Monday and booked a test, receiving the result a day later.
Mr Stewart has completed the track and trace details and he is self-isolating.
Download ‘StopCOVID NI’ from the Google or Apple App store now to help stop the spread of coronavirus.
Sadly I have tested positive for Covid-19 today.
Felt really unwell Monday, booked test Tuesday & result today. Very fast & efficient.
Feeling ill, head pounding & really fatigued… ?
Have completed track & trace / StopCOVIDNI App & now self isolating. #InThisTogether
