The isolation period for close contacts may be reduced in a bid to ease pressure on the health service and businesses.
The Government is to discuss the matter tomorrow following new advice from the European Centre for Disease Prevention and Control.

However it comes with the warning that it is not evidenced based.
The Irish Congress of Trade Unions says any changes to isolation rules must be led by public health advice and not the demands of business.
