Question is why are there so many hospitalizations now. And I think that article mentions because it skipped a year. A few different theories.
Theres a theory in the pediatric world right now that many children didnt get exposure to the usual winter bugs (rsv, parainfluenza, influenza, old corona) this past winter becuase of all the covid restrictions and consequently didnt gain natural immunity to it - and therefore there may be a summer wave of usual winter bugs as kids start to interact with each other more. Its something that played out in Australia in their summer (December this year), and were starting to see in the inpatient pediatric floors.
