Mae effaith yr amrywiolyn Omicron ar iechyd yn dal i gael ei asesu. Ar hyn o bryd nid oes tystiolaeth sylweddol i awgrymu y bydd yr amrywiolyn Omicron yn arwain at fath mwy difrifol o salwch, ond mae sylw manwl a chyson yn cael ei roi i’r data.
The health impact of the Omicron variant is still being assessed. Currently there is no substantial evidence to suggest the Omicron variant will lead to a more severe form of illness but the data is being kept under constant review.
