The Acting Chief Medical Officer, Dr Ronan Glynn, has warned that the improper wearing face coverings could increase the risk from Covid-19.
Speaking at last night's National Public Health Emergency Team briefing, Dr Glynn said that although the vast majority of people are now wearing coverings when its required to do so, some are not wearing them properly.
Face coverings are now mandatory in certain places including on public transport and in retail outlets Dr Glynn said it appears that around 90% of people are wearing face coverings where appropriate, but he warned that too many people are wearing them under their chin or leaving their nose exposed.
