We are already recommending that travellers from Wuhan should self-isolate for 14 days, even if they do not have symptoms, due to the increased risk from that area.
Rydym eisoes yn argymell y dylai teithwyr o Wuhan aros gartref ac osgoi cysylltiad ag eraill am 14 diwrnod, hyd yn oed os nad oes ganddynt symptomau, oherwydd y risg uwch o’r ardal honno.
