WHO advises that people always consult and abide by local authorities on recommended practices in their area. An international and multidisciplinary expert group brought together by WHO reviewed evidence on COVID-19 disease and transmission in children and the limited available evidence on the use of masks by children.
Based on this and other factors such as childrens’ psychosocial needs and developmental milestones, WHO and UNICEF advise the following:
Children aged 5 years and under should not be required to wear masks. This is based on the safety and overall interest of the child and the capacity to appropriately use a mask with minimal assistance.
WHO and UNICEF advise that the decision to use masks for children aged 6-11 should be based on the following factors:
Whether there is widespread transmission in the area where the child resides
The ability of the child to safely and appropriately use a mask
Access to masks, as well as laundering and replacement of masks in certain settings (such as schools and childcare services)
Adequate adult supervision and instructions to the child on how to put on, take off and safely wear masks
Potential impact of wearing a mask on learning and psychosocial development, in consultation with teachers, parents/caregivers and/or medical providers
Specific settings and interactions the child has with other people who are at high risk of developing serious illness, such as the elderly and those with other underlying health conditions
WHO and UNICEF advise that children aged 12 and over should wear a mask under the same conditions as adults, in particular when they cannot guarantee at least a 1-metre distance from others and there is widespread transmission in the area.
