Arweiniodd yrAthro Valerie O'Donnellyn Ysgol Feddygaeth Prifysgol Caerdydd adolygiad o dystiolaeth ryngwladol a oedd yn cynnig bod gan rinsio eich ceg botensial damcaniaethol i leihau trosglwyddiad y coronafeirws. Profodd y tîm effaith cegolch ar feirws SARS-CoV2 o dan amodau tiwb profi labordy a oedd yn dynwared gwddf unigolyn. Daethant i’r casgliad bod rhai mathau o gymysgeddau cegolch yn anactifadu heintusrwydd coronafeirws wrth iddynt ddod i gysylltiad am 30 eiliad. Cyflwynwyd canfyddiadau tebyg yn ddiweddar gan astudiaethau annibynnol mewn o leiaf dri labordy arall o amgylch y byd. Mae treial clinigol ar wahân sy’n cael ei arwain gan Brifysgol Caerdydd nawr yn profi a all cegolch anactifadu’r feirws yn y geg.
Professor Valerie O'Donnellat Cardiff University’s School of Medicine led an international evidence review which proposed that oral rinsing has a theoretical potential to reduce coronavirus transmission. The team tested the impact of mouthwash on the SARS-CoV2 virus under laboratory test tube conditions that mimicked a person’s throat. They found that certain types of mouthwash preparations inactivated coronavirus infectivity during a 30 second exposure. Similar findings have recently been presented by independent studies in at least three other laboratories around the world. A separate clinical trial being led by Cardiff University is now testing whether mouthwash can inactivate the virus in the mouth.
