Ar ôl cynnydd mewn achosion o’r is-amrywiolion BA.4 a BA.5 yn ystod mis Mehefin fe wnaethom ymestyn mynediad at brofion llif unffordd am ddim i’r cyhoedd sydd â symptomau COVID-19 tan 31 Gorffennaf. Y disgwyliad oedd i’r don gyrraedd ei hanterth cyn diwedd mis Gorffennaf. Nododd cyngor gan y Gell Cyngor Technegol, dyddiedig 22 Gorffennaf, fod y pwysau ar y GIG wedi cyrraedd uchafbwynt yng nghanol mis Gorffennaf, ac mae’n ymddangos ei fod wedi gostwng ers hynny. Roedd tua 18 o dderbyniadau i’r ysbyty oherwydd COVID-19 y dydd ar 26 Gorffennaf, yn dilyn uchafbwynt o 28 o dderbyniadau’r dydd bythefnos ynghynt. Ar y cyfan, mae lefelau marwolaethau yn parhau i fod ar lefelau is o gymharu â thonnau blaenorol.
After an increase in cases of BA.4 and BA.5 sub-variants during June we extended access to free lateral flow tests for members of the public with symptoms of COVID-19 until the 31 of July. The expectation was for the wave to reach its peak before the end of July. Advice from TAC, dated 22 July reported NHS pressures peaked in mid-July, and appear to have decreased since. There were around 18 hospital admissions for COVID-19 a day as of 26 July, following a peak of 28 admissions per day two weeks before. Overall deaths remain at lower levels compared to previous waves.
