In general, children aged 5 years and under should not be required to wear masks. This advice is based on the safety and overall interest of the child and the capacity to appropriately use a mask with minimal assistance. There may be local requirements for children aged 5 years and under to wear masks, or specific needs in some settings, such as being physically close to someone who is ill. In these circumstances, if the child wears a mask, a parent or other guardian should be within direct line of sight to supervise the safe use of the mask.
