One crucial factor in ensuring hospitals can provide care is the level of staff absences. You've said, Minister, that there were around 10,000 staff absences in the Welsh NHS last week, and 98 per cent of British Medical Association Cymru members said they're concerned about staffing levels because of those absences. Last week, I asked the First Minister about providing higher grade masks for NHS staff, and he told me that the Welsh Government's policy was based on the advice of a UK-wide specialist group and, at the time, it wasn't advising making these masks available nationally. Following that exchange, Minister, concerns were relayed to me by doctors who feared that that advice was not scientifically sound in terms of ensuring their safety. I understand that the UK advice has now been updated and new guidance states that FFP3 masks must be worn by staff caring for patients with suspected or confirmed COVID infection. So, could you confirm whether the Welsh Government has received this new advice, and, if so, whether you intend to implement it, and, if you do, finally, could you give us an idea of timescale in terms of how long it'll take to fit-test all remaining front-line staff, to get these respirators to where they're needed, please?
