The evidence remains clear that maintaining a 2 metre distance and good hand hygiene is the most effective way to protect yourself and others from contracting coronavirus, but the updated guidance from the WHO says 3 layer face coverings could help provide some control of the virus in specific circumstances.


This updated advice only applies to people who are not showing symptoms of coronavirus. People who are symptomatic must self\-isolate for 7 days and get a test, as set out in existing guidance. Unless the test shows a negative result, they must not go out during this time, even with a face covering or mask.


Health Minister Vaughan Gething said:



> Washing your hands, avoiding touching your face and maintaining a 2 metre distance from others remain the best way of stopping the spread of the virus.  
> 
>   
> 
> “On Friday, the WHO updated their guidance on face coverings, advising that they should be considered in settings where maintaining social distancing is difficult. However, to be crystal clear, wearing a face covering does not replace the need for social distancing or washing your hands regularly.  
> 
>   
> 
> “Further scientific evidence is needed on the benefits to the wider public of wearing face coverings, but observational findings so far suggest that homemade or purchased 3 layer face\-coverings might reduce transmission from one person to another if made, worn, handled and disposed of properly.  
> 
>   
> 
> “Therefore, on balance, we are recommending to the people of Wales that 3 layer face\-coverings should be used in situations where social distancing measures can be more difficult to achieve, for example, on public transport. We are not recommending their use outdoors.  
> 
>   
> 
> “The wearing of face coverings will not be mandatory, but we will encourage people to do this for the benefit of themselves and others.


The minister stressed that this advice only applies to people who are not showing symptoms of coronavirus, adding:



> “Anyone who has a high temperature, a new, continuous cough or a loss or change to their sense of smell or taste must self\-isolate for a minimum of 7 days and get a test as quickly as possible. Unless the test shows a negative result, people must not go out during this time, even with a face covering or mask.

Mae'r dystiolaeth yn glir mai cadw pellter o 2 fetr a sicrhau hylendid dwylo da yw’r ffordd fwyaf effeithiol o ddiogelu eich hun ac eraill rhag dal coronafeirws, ond mae’r canllawiau diweddaraf gan Sefydliad Iechyd y Byd yn dweud y gallai gorchuddion wyneb tair haen helpu i reoli’r feirws mewn rhai amgylchiadau.


Mae’r cyngor diweddaraf hwn yn berthnasol dim ond i bobl nad oes ganddynt symptomau coronafeirws. Mae’n rhaid i bobl â symptomau hunanynysu am saith diwrnod a chael prawf, fel y nodwyd yn y canllawiau presennol. Oni bai bod prawf yn dangos canlyniad negatif, ni ddylent fynd allan yn ystod y cyfnod hwn, dim hyd yn oed os ydynt yn gwisgo gorchudd wyneb neu fasg. 


Dywedodd y Gweinidog Iechyd Vaughan Gething:



> Golchi’ch dwylo, osgoi cyffwrdd eich wyneb a chadw pellter o 2 fetr oddi wrth eraill yw’r ffordd orau o atal lledaeniad y feirws. 
> 
> 
> “Ddydd Gwener, diweddarodd Sefydliad Iechyd y Byd eu canllawiau ar orchuddion wyneb, gan gynghori y dylid ystyried eu gwisgo mewn lleoliadau lle mae’n anodd cadw pellter cymdeithasol. Ond hoffwn bwysleisio nad yw gwisgo gorchudd wyneb yn dileu’r angen i gadw pellter cymdeithasol a golchi’ch dwylo yn rheolaidd.
> 
> 
> “Mae angen tystiolaeth wyddonol bellach ar fanteision gorchuddion wyneb i’r cyhoedd. Ond hyd yma mae canfyddiadau arsylwadol yn awgrymu y gall gorchuddion wyneb tair haen, sy’n cael eu prynu neu eu gwneud gartref, atal trosglwyddiad haint o un person i berson arall os yw’r gorchuddion hyn yn cael eu gwneud, eu gwisgo, eu trin a’u gwaredu yn briodol. 
> 
> 
> “Felly rydym yn argymell y dylai pobl Cymru wisgo gorchuddion wyneb tair haen mewn sefyllfaoedd lle gall fod yn anoddach cadw pellter cymdeithasol, fel ar gludiant cyhoeddus. Nid ydym yn argymell eu defnyddio yn yr awyr agored.
> 
> 
> “Ni fydd yn orfodol i bobl wisgo gorchuddion wyneb, ond rydym yn eu hannog i wneud hyn er eu lles eu hunain ac eraill.


Pwysleisiodd y Gweinidog mai dim ond i bobl nad oes ganddynt symptomau coronafeirws y mae’r cyngor hwn yn berthnasol, gan ychwanegu:



> Mae’n rhaid i unrhyw un sydd â thymheredd uchel, peswch newydd, cyson, neu sydd wedi colli eu gallu i arogli neu flasu, neu wedi gweld newid yn yr ymdeimlad hwnnw, hunanynysu am o leiaf saith diwrnod a chael prawf cyn gynted â phosibl. Oni bai bod prawf yn dangos canlyniad negatif, ni ddylent fynd allan yn ystod y cyfnod hwn, dim hyd yn oed os ydynt yn gwisgo gorchudd wyneb neu fasg.
