Mae cynnydd sylweddol wedi bod yn ein dealltwriaeth o’r modd y caiff COVID-19 ei drosglwyddo drwy ddefnynnau, gronynnau aerosol bach ac ar arwynebau, gyda'r risgiau mwyaf sylweddol yn codi dan do, mewn lleoliadau gorlawn heb ddigon o awyr iach. Wrth i dymor yr ŵyl agosáu, dylai pawb fod yn ymwybodol o’r risgiau hyn a gwybod beth i’w wneud i’w hatal neu eu hosgoi. Croesewir ymgyrch genedlaethol ar y cyd, gan ganolbwyntio ar ein cyfrifoldeb ar y cyd i roi mesurau cadw pellter cymdeithasol ar waith, gwisgo gorchuddion wyneb pan fo angen, golchi ein dwylo yn rheolaidd ac aros y tu allan pan fo hynny’n bosibl.
There has been considerable progress in the understanding of COVID-19 transmission through droplets, small aerosol particles and on surfaces, with the most significant risks being indoors, in crowded and unventilated settings. As the festive season approaches, everyone should be aware of these risks and know what to do to prevent or avoid them. A concerted national campaign is welcomed, focusing on our collective responsibility to put into practice social distancing, wear face coverings where required, wash our hands regularly and stay outside whenever we can.
