It requires the showing of some symptoms, otherwise it is not a disease. As an example, people with HIV don't necessarily have AIDS--the latter is the name of the auto-immune disease that typically shows up eventually in patients who test positive for HIV and don't get treatment. Likewise, COVID-19 is the disease which has symptoms including severe coughing, fever, and shortness of breath. But if you have absolutely no symptoms whatsoever, but your blood tests positive, you do not have COVID-19. The positive result, if it isn't a false positive, indicates that your blood contains the SARS-CoV-2 virus, and therefore you are presumably fighting an asymptomatic infection. But by the terminology used by pathologists, you wouldn't have COVID-19. So back to the original point, children generally don't get COVID-19. They may get infected by the virus, but without showing any symptoms. No symptoms, no disease, no COVID-19 classification.
