Masks do not protect against infections. It is stated on the box itself by a manufacturer. Cloth coverings do not filter nanoparticles. Adults and children do not know how to properly handle masks. The biggest Canadian Children's hospital does not recommend for children to wear masks upon their return to schools. Please, look up some real science. Even OSHA states that surgical masks "are fluid resistant, disposable, and loose-fitting protection that create a physical barrier between the mouth and nose of the wearer and potential contaminants in the immediate environment. They are commonly used in health care settings for the protection of the patient and they are also often used to prevent splashes from contacting the face of the wearer. However, surgical masks do not seal tightly to the wearer’s face, nor do they provide a reliable level of protection from inhaling smaller airborne particles". Also, personally, I have to wear glasses to see and drive, and they steam up every time I put a mask on making it impossible to function normally.
