0.0113 is the percentage of children currently in ICU to date from NSW's 25,617 locally aquired cases reported since the 16th of June.
0.000 is the percentage of children with no known health issues currently in ICU from the same cases as reported above.
Extrapolated out to 1,000,000 cases the result suggests a possible 113 children with known health issues could end up in ICU. (Not a prediction)
After more than 18 months of this pandemic most countries worst effected by covid have not even clocked up covid cases in 15% of their population.
Use NSW's entire population and its up to around 900 children with known health issues who could end up in ICU .... 15% of 900 is 135 (again not a prediction)
