Caiff y newidiadau i brofi mewn ysbytai eu gwneud nawr oherwydd, yn ystod cyfnodau pan ceir nifer uchel o achosion o COVID-19 yn y gymuned, effaith gymharol fach y mae hyn wedi’i chael ar nifer y derbyniadau i’r ysbyty a marwolaethau, ac mae nifer y marwolaethau sy’n gysylltiedig â throsglwyddiad nosocomiaidd hefyd wedi gostwng yn sylweddol.
The changes to testing in hospital settings are being made now as during high community incidence of COVID-19 there has been a relatively modest impact on hospital admissions and mortality, whilst the extent of nosocomial associated mortality has also significantly reduced.
