Something that strikes me as off with this study if only 1.8% of kids tested positive for COVID during the 10 month study period (64,898/3.7 million). This seems way too low and would inappropriately inflate post-COVID myocarditis risk in kids.

For reference, seroprevalence was estimated to be 25.3% among kids at the beginning of February. covid.cdc.gov/covid-data-tra…
Re the myo study ⬆️, I would tend to look at 218 total (86 in kids with covid) cases of myocarditis out of 3.7 mill kids over 10 months of the pandemic as reassuring. But this points out why it is crucial to get the denominator right. Please correct me if I have misunderstood. 
And, just to clarify, 1.8% is not the disease prevalence in their pediatric population, but the percent of pediatric visits where there was a COVID+ diagnosis. It puts into perspective how rare of a reason COVID is for medical visits (this was clinic and hospital settings)
But the raw # of covid + patients with myocarditis/population was lower in the children than the other age groups. So it would be wrong for people to walk away from this study thinking kids are at higher risk of covid myocarditis than adults.
