The Northern Irish Minister for Health Robin Swann is self-isolating after receiving a close proximity notification from the Covid-19 tracker app.
Several other other representatives have also received app notifications to isolate.
In a social media post, Mr Swann said he will be carrying out his ministerial duties from home for the required two week period.
We are all in this together.
Earlier this evening I received a close proximity notification via our StopCOVID NI App, so I will be working from self isolation for the next 14 days.

He has no symptoms and will only require a test if he develops one of the symptoms of the virus.
Stormont Assembly member Kellie Armstrong says it shows how technology can help break the disease's chain of transmission.
Earlier this month, deputy first minister Michelle O'Neill was also forced to self-isolate after a member of her family tested positive for Covid-19.
Yesterday, 1,039 cases of the virus were confirmed in the North, with an additional five deaths also reported to the Department of Health.
