The Irish College of General Practitioners is advising that a face covering is superior to a face visor when trying to limit the spread of Covid-19.
Speaking on RTÉ's News at One, Dr Nuala O'Connor, who is the Covid-19 lead for the ICGP, said that while a visor is better than wearing nothing, it does not offer as much protection from the virus.
She said that the virus comes out by cough, by breath and sneezing so wearing something that covers the nose and mouth snuggly gives the best protection and limits spread.
Dr O'Connor said that visors may be necessary in some situations, for example if a GP needs to communicate with someone hard of hearing, where hearing through a facemask might be a difficulty.
