I wrote to Assembly Members, MPs, Council Leaders and Chairs of Health Boards on 26 March to provide an update on the outbreak.
Ar 26 Mawrth ysgrifennais at Aelodau’r Cynulliad, ASau, Arweinwyr Cynghorau a Chadeiryddion Byrddau Iechyd i roi gwybod iddynt am y sefyllfa ddiweddaraf o ran yr achosion hyn.
