An inquiry into the recent measles outbreak centred on the Swansea area gets underway at the Senedd today.
The Welsh Government's Health and Social Care Committee will consider the factors leading to the outbreak, the actions taken by public health professionals in working with other agencies and in response to the outbreak.
Among those giving evidence will be Health Minister Mark Drakeford, representatives from the Abertawe Bro Morgannwg, Betsi Cadwaladr and Aneurin Bevan health boards and Public Health Wales.
The committee will also look at what lessons can be learned from the outbreak.
