16. Is Public Health Wales contacting all those affected?

No. We have concluded, after legal advice and consultation with the ICO, that writing to all those affected is not required in this case because the risk to them is considered low. If anyone is concerned that their data or that of a close family member may have been breached, they should email us at PHW.data@wales.nhs.uk or call 0300 003 0032 to discuss their concerns.
