If staff are a contact of someone with a respiratory infection but do not live with them or did not stay in their household overnight, they are at lower risk of becoming infected.
Os yw staff wedi dod i gysylltiad â rhywun sydd â haint anadlol ond nid ydynt yn byw gyda nhw, ac ni arhoson nhw yn eu cartref dros nos, mae llai o berygl iddynt gael eu heintio.
