To show you how asinine the CDC is and its director and staff, the WHO, a corrupt and inept agency itself, just pure incompetence, but the WHO says children < 5, NO masks, vs CDC says masks needed

I have written here before, take the CDC down to the very studs and fumigate it, fire director and top 20 highly paid highly underworked inept officials, and then relocate it to the Alcatraz rock

WHO and its position on masks for children:

Are there situations where children aged 5 years and under may wear or be required to wear a mask?

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. 

CDC and its current position on masks in children:

CDC Guidance for COVID-19 Prevention in K-12 Schools as of Jan 2022:

• CDC recommends universal indoor masking by all* students (ages 2 years and older), staff, teachers, and visitors to K-12 schools, regardless of vaccination status.
