Hospitals and medical centres could face a shortage of doctors and nurses tomorrow.
That's the warning of the Association of Salaried Medical Specialists which says there hasn't been enough time for medical professionals to arrange care for their children.
Schools are closed and children now need to be cared for at home.
Essential workers were given extra time to make arrangements, but only until tomorrow.
Sarah Dalton is executive director of the Association of Salaried Medical Specialists.
She speaks to Corin Dann.
