Nid oes unrhyw amrywiolion sy'n peri pryder arwyddocaol ar y gorwel agos hyd y gwyddom. Ond bydd SARS-CoV2 yn newid yn barhaus ac mae perygl o hyd y gallai amrywiolion y dyfodol naill ai fynd heibio i imiwnedd y boblogaeth neu achosi salwch mwy difrifol mewn unigolion a fydd wedi’u heintio. Dylem barhau i weithio ar draws pedair gwlad y DU i ddatblygu dulliau domestig a rhyngwladol effeithiol o gadw golwg ar COVID-19 a phathogenau anadlol eraill.
We are unaware of any significant variants of concern on the immediate horizon but SARS-CoV2 will continue to mutate and there remains a risk of future variants either bypassing population immunity or causing more serious illness in infected individuals. We should continue to work across the 4 UK Nations to develop effective domestic and international surveillance for COVID-19 and other respiratory pathogens.
