If you are a contact of someone with a respiratory infection but do not live with them or did not stay with them overnight, you are at lower risk of infection.
Os ydych wedi dod i gysylltiad â rhywun sydd â haint anadlol ond nid ydych yn byw gyda nhw, ac ni arhosoch yn eu cartref dros nos, mae llai o berygl ichi gael eich heintio.
