A German study involving over 25,000 children reveals that major negative impacts on the physical, psychological, and behavioral health of children may be far more widespread than reported in the media and by government officials -- affecting approximately 68% and contributing to 24 distinct health complaints, according to parent submitted observations. 

A concerning study conducted in Germany has been posted online as a preprint (not yet peer-reviewed) titled, "Corona children studies "Co-Ki": First results of a Germany-wide registry on mouth and nose covering (mask) in children," describing the results of 17,854 parent submitted reports on health complaints or impairments experienced as a result of wearing masks by their 25,930 children.

The study was designed to both explore the accumulating narratives reported by parents, educators, and doctors about increasing problems and health complaints in children and adolescents wearinng masks, as well as to provide the first known online registry where parents, doctors, teachers, and others can enter their first-hand observations. The registry and the questionnaire can be found online at www.co-ki-masken.de
