Minister for Health Simon Harris has said "more restrictions" including the potential widespread closure of schools may be needed if Ireland is to successful overcome the Covid-19 outbreak.

Mr Harris said any new restrictions need to be "introduced at the right time" to ensure they have the best effect, saying the reality is "this is not Fortress Ireland" and that "we can't fool ourselves" this country can avoid the virus.

Speaking on RTÉ's Prime Time programme, Mr Harris said "we have to be very honest with people" and that "we are going to see a lot more cases here".

Defending the Government's decision not to ban travel to this country from affect areas or close schools to date, he said:

"There may be a time when we close schools. As of now we need you to take all measures to keep family well and look after those in the community. But there will in all likelihood be a point when we have to introduce more restrictions."
