Mae profion COVID-19 rheolaidd wedi cael eu cynnig i weithwyr iechyd a gofal cymdeithasol, staff addysg, myfyrwyr a gweithwyr yn y sectorau cyhoeddus a phreifat ers dechrau 2021. Mae'r grwpiau hyn wedi cael dyfeisiau prawf llif unffordd (LFD) i'w defnyddio'n rheolaidd, ddwywaith yr wythnos fel arfer, ar gyfer unigolion nad oes ganddynt unrhyw symptomau. Dod o hyd i achosion a lleihau achosion o drosglwyddo’r feirws yw’r nod. Mae unigolion nad ydynt yn gallu gweithio gartref, gofalwyr di-dâl a gwirfoddolwyr hefyd wedi gallu manteisio ar gael pecynnau hunan-brawf llif unffordd ers mis Ebrill.
Regular COVID-19 testing has been offered to health and social care workers, education staff, students and workers in the public and private sector since the beginning of 2021. These groups have been provided with Lateral Flow Devices (LFDs) for regular use, usually twice weekly, for individuals that do not have any symptoms. The purpose is to find cases and reduce transmission of the virus. People who cannot work from home, un-paid carers and volunteers have also been able to access lateral flow self-test kits since April.
