Anfonwyd y swabiau yr effeithir arnynt i Gymru yn uniongyrchol oddi wrth y gwneuthurwr COPAN rhwng 18 Tachwedd a 14 Rhagfyr 2020.  Mae NWSSP wedi ynysu’r holl gyflenwad perthnasol yn rhagofal wrth gynnal ymchwiliadau pellach.
The affected swabs were shipped into Wales direct from the manufacturer COPAN between 18 November and 14 December 2020. NHS Wales Shared Services Partnership has isolated all relevant supplies as a precaution while further investigations are undertaken.
