Pa drafodaethau y mae Llywodraeth Cymru wedi'u cael ynglŷn â gwella gwybodaeth am heintiau a drosglwyddir yn yr awyr drwy ddarparu gwybodaeth iechyd y cyhoedd am ddefnyddio masgiau anadlol a hidlyddion aer HEPA?
The Welsh Government works closely with Public Health Wales on public health information about all communicable diseases, including airborne infections. Our guidance for the general public on the management of acute respiratory infections includes when consideration of wearing a face mask may be appropriate.
With regards to HEPA air filter purification, work is ongoing with the NHS including representatives from the Scientific Advisory Group for Emergencies (SAGE), to validate effectiveness in healthcare settings. Trials on their use within NHS Wales are being undertaken in conjunction with several Health Boards to try to validate their effectiveness before recommending their widescale use within the healthcare environment.
