This week all measures for the time taken to reach positive cases and close contacts have seen a decrease compared to the previous week.
Yr wythnos hon gwelwyd gostyngiad ym mhob un o’r mesurau ar gyfer yr amser a gymerwyd i gyrraedd achosion positif a chysylltiadau agos, o’i gymharu â’r wythnos flaenorol.
