Both childhood CKD and adult CKD have a high incidence rate, while the awareness and prevention rates are low. World Kidney Day was established to draw attention to CDK and raise the level of awareness of CKD. Acute kidney injury (AKI) in children due to various factors is also common, but often overlooked. For example, many children with severe infectious diarrhea do not actually end up dying from the infection, but from AKI caused by diarrhea. Many adults with CKD have a history of recurrent respiratory infections in childhood. Therefore, recurrent respiratory infections, especially adenitis of the tonsils, must be taken seriously and treated more intensively. CKD in children is not only a painful disease for children, but also leads to a higher mortality rate in children and affects their growth and development as well as their life as adults, so it should be taken seriously by the public. Early detection and early treatment can prevent greater tragedies, which is the real meaning of this year’s World Kidney Day with children as the theme.
