Mae’r rheoliadau Diogelu Iechyd, sy’n gosod cyfyngiadau ar fywyd cyhoeddus yng Nghymru, wedi llwyddo i reoli lledaeniad syndrom anadlol acíwt difrifol coronafeirws 2 (SARS-CoV-2). Bu lleihad yn lledaeniad ac effeithiau’r feirws, ac mae’r rhaglen frechu’n mynd o nerth i nerth, ac felly byddai bwriad i lacio ar y cyfyngiadau’n raddol yn cael ei weld fel ymateb cymesur i’r risg cymharol i iechyd y cyhoedd. Fodd bynnag, mae’r penderfyniad i aros i gael dadansoddiad manylach o’r amrywiolyn B.1.617.2 o India, sy’n peri pryder, yn un doeth. Mae nifer yr achosion a’r clystyrau’n yn cael eu monitro’n agos, a bydd y data’n cael ei archwilio’n fanwl i asesu pa mor drosglwyddadwy yw’r amrywiolyn hwn; am ba hyd y mae’r unigolyn yn heintus; ac i ba raddau y mae’r feirws yn gallu osgoi amddiffyniad y system imiwnedd. Gellir defnyddio’r wybodaeth hon i benderfynu ar natur, amseriad, a threfn y camau llacio a gymerir.
Health Protection regulations imposing restrictions on public life in Wales have been successful in controlling the spread of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). There has been a decline in the spread and impact of the virus, the vaccination roll out continues at pace, and the intention to gradually ease  restrictions would be viewed as a proportionate response to the relative risk to public health. However, the decision to pause and wait for more detailed analysis of the B.1.617.2 variant of concern from India is prudent. Case numbers and clusters are being closely monitored and data will be interrogated to assess transmissibility, period of infection and evasion of immune defences; information which can be used to determine the nature, timing and sequencing of on-going relaxations.
