O ran gorchuddion wyneb, mae ein hailasesiad diweddar o’r dystiolaeth gan Dechnoleg Iechyd Cymru yn dal i ddod i’r casgliad mai tystiolaeth wan sydd o’r effaith fanteisiol fychan bosibl ar drosglwyddiad a bod effeithiau negyddol posibl hefyd. Oherwydd hyn, rwy’n cytuno y dylem ddal i gynghori bod gorchuddion wyneb tair haen yn cael eu hargymell mewn lleoliadau prysur dan do lle nad yw’n bosibl cadw pellter cymdeithasol.
On face coverings our recent re-assessment of the evidence by Health Technology Wales continues to conclude that there is weak evidence of a potential small beneficial effect on transmission and that there are also potential negative effects. On this basis I agree that we should continue to advise that three layered face coverings are recommended in crowded indoor settings where it is not possible to maintain social distancing.
