Diolch yn fawr. Well, I absolutely understand the concern of parents in these very difficult times. When your child is ill and you know that there's a potential that they could get invasive strep A, then you understand why we've seen a huge increase in contact numbers. I think we had 18,000 calls on the weekend, and 54 per cent of the call activity on Sunday related to children who were under 14. So, we have got a multi-agency incident management team in place. There has, as you said, been a surge in demand for antibiotics, which did lead to a temporary disruption in supply. We are working with the UK Government to speed up the movement of additional stock into supply chains, and we've issued guidance on alternative antibiotic choices and on the administration of tablets and capsules to children where penicillin and liquid antibiotics are unavailable. Also, we've given advice on how solid dosage can be given to people who have swallowing difficulties where there is a shortage of liquid medicine. So, we are giving that advice, that advice has gone out, and, obviously, if there are alternatives, as there are, then we need to keep an eye on that in terms of the price of the antibiotics.
