Mae Llywodraeth Cymru hefyd wedi cytuno i leihau'r cyfnod hunanynysu o saith diwrnod i bum diwrnod llawn i bawb sy'n profi'n bositif am Covid-19. Dylent gymryd dau brawf llif ochrol 24 awr ar wahân ar ddiwrnod pump a chwech i weld a ydynt yn parhau i fod yn heintus ac yn gallu trosglwyddo Covid-19 i eraill. I gydnabod y cyfnod ynysu byrrach, bydd taliad y cynllun cymorth hunanynysu yn dychwelyd i'r gyfradd wreiddiol o £500 i bawb sy'n gymwys ac yn colli incwm o ganlyniad i hunan-ynysu.
The Welsh Government has also agreed a reduction of the self-isolation period from seven days to five full days for everyone who tests positive for Covid-19. Two negative lateral flow tests taken 24 hours apart should be taken on day five and six to help determine if they are still infectious and potentially pass COVID-19 to others. In recognition of the shorter isolation period, the self-isolation support scheme payment will revert to the original rate of £500 for all those who are eligible and lose income as a result of self-isolation.
