The number of positive coronavirus cases in Northern Ireland now stands at 62 - a rise of 10 from Monday.

The total number of tests completed is 1,338.

The total in the Republic of Ireland stands at 292 after 69 new cases were revealed on Tuesday.

"People with mild symptoms - new persistent cough and/or fever - should stay at home and self-isolate," the Department of Health said.

"They will not require testing and will not therefore be included in testing totals."

'Level of risk'

Meanwhile, an umbrella body for Catholic school principals has said schools in Northern Ireland should close immediately.

An open letter to the education minister said many parents had "already started making your decisions for you by keeping children at home".

Kieran O'Neill, chairman of the Catholic Principals' Association, called on Peter Weir to "show leadership in line with the department of education in the Republic of Ireland and close all schools with immediate effect".

"The level of risk associated with keeping schools open is high," he said.

"The close interaction of staff, children, parents and visitors increases the likelihood of community transmission of Covid-19."

On Monday, Peter Weir said schools would close in the future but he would "not be giving weight to popular opinion on social media".

All schools and colleges in the Republic of Ireland have been closed.

The leader of the Catholic Church in Ireland has repeated his call for Stormont to consider closing all schools over coronavirus.

Speaking on BBC Radio Ulster's Good Morning Ulster programme, Archbishop Eamon Martin said "a specific date" of closure was needed.

Since Monday, special schools in Belfast have been closed indefinitely.
